Ques 29. Why can't I use an assignment in an expression?

Many people used to C or Perl complain that they want to use this C idiom:

while (line = readline(f)) {
  ...do something with line...
}

 
where in Python you're forced to write this:

while True:
  line = f.readline() if not line:
  break
...do something with line...

The reason for not allowing assignment in Python expressions is a common, hard-to-find bug in those other languages, caused by this construct:

 
if (x = 0) {
...error handling...
}
else {
...code that only works for nonzero x...
}

 
The error is a simple typo: x = 0, which assigns 0 to the variable x, was written while the comparison x == 0 is certainly what was intended.

 
Many alternatives have been proposed. Most are hacks that save some typing but use arbitrary or cryptic syntax or keywords, and fail the simple criterion for language change proposals: it should intuitively suggest the proper meaning to a human reader who has not yet been introduced to the construct.

Ques 30. How do you set a global variable in a function in Python?

x = 1 # make a global
def f():
  print x # try to print the global
  for j in range(100):
    if q>3:
      x=4

 
Any variable assigned in a function is local to that function. unless it is specifically declared global. Since a value is bound to x as the last statement of the function body, the compiler assumes that x is local. Consequently, the print x attempts to print an uninitialized local variable and will trigger a NameError.


The solution is to insert an explicit global declaration at the start of the function:

 
def f():
  global x
  print x # try to print the global
  for j in range(100):
    if q>3:
      x=4

 
In this case, all references to x are interpreted as references to the x from the module namespace.

Ques 31. What are the rules for local and global variables in Python?

In Python, variables that are only referenced inside a function are implicitly global. If a variable is assigned a new value anywhere within the function's body, it's assumed to be local.

If a variable is ever assigned a new value inside the function, the variable is implicitly local, and you need to explicitly declare it as 'global'. 


Though a bit surprising at first, a moment's consideration explains this. On one hand, requiring global for assigned variables provides a bar against unintended side-effects. On the other hand, if global was required for all global references, you'd be using global all the time.

You'd have to declare as global every reference to a built-in function or to a component of an imported module. This clutter would defeat the usefulness of the global declaration for identifying side-effects.

Ques 32. How do I share global variables across modules?

The canonical way to share information across modules within a single program is to create a special module (often called config or cfg).

Just import the config module in all modules of your application; the module then becomes available as a global name. Because there is only one instance of each module, any changes made to the module object get reflected everywhere.


For example:

config.py: 
x = 0 # Default value of the 'x' configuration setting

mod.py: 
import config
config.x = 1

main.py:
import config
import mod
print config.x

 
Note that using a module is also the basis for implementing the Singleton design pattern, for the same reason.

Ques 33. How can I pass optional or keyword parameters from one function to another?

Collect the arguments using the * and ** specifier in the function's parameter list; this gives you the positional arguments as a tuple and the keyword arguments as a dictionary. You can then pass these arguments when calling another function by using * and **:

def f(x, *tup, **kwargs):
  kwargs['width']='14.3c'
  g(x, *tup, **kwargs)

In the unlikely case that you care about Python versions older than 2.0, use 'apply':

def f(x, *tup, **kwargs): 
  kwargs['width']='14.3c'
  apply(g, (x,)+tup, kwargs)

Ques 34. How do you make a higher order function in Python?

You have two choices: you can use nested scopes or you can use callable objects.

For example, 
suppose you wanted to define linear(a,b) which returns a function f(x) that computes the value a*x+b. Using nested scopes:

def linear(a,b): 
  def result(x):
    return a*x + b
      return result

Or using a callable object: 

class linear: 
  def __init__(self, a, b):
    self.a, self.b = a,b
    def __call__(self, x):
      return self.a * x + self.b

In both cases: 
taxes = linear(0.3,2)
gives a callable object where taxes(10e6) == 0.3 * 10e6 + 2.

 
The callable object approach has the disadvantage that it is a bit slower and results in slightly longer code. However, note that a collection of callables can share their signature via inheritance:

class exponential(linear): 
  # __init__ inherited
  def __call__(self, x):
    return self.a * (x ** self.b)

Object can encapsulate state for several methods: 
class counter:
  value = 0
    def set(self, x): self.value = x
    def up(self): self.value=self.value+1
    def down(self): self.value=self.value-1
    count = counter()
    inc, dec, reset = count.up, count.down, count.set

Here inc(), dec() and reset() act like functions which share the same counting variable.

Ques 35. How do I copy an object in Python?

In general, try copy.copy() or copy.deepcopy() for the general case. Not all objects can be copied, but most can.

Some objects can be copied more easily. Dictionaries have a copy() method: newdict = olddict.copy()

Sequences can be copied by slicing: new_l = l[:]

Ques 37. How do I convert a string to a number?

For integers, use the built-in int() type constructor, e.g. int('144') == 144. Similarly, float() converts to floating-point, e.g. float('144') == 144.0.

By default, these interpret the number as decimal, so that int('0144') == 144 and int('0x144') raises ValueError.

int(string, base) takes the base to convert from as a second optional argument, so int('0x144', 16) == 324. If the base is specified as 0, the number is interpreted using Python's rules: a leading '0' indicates octal, and '0x' indicates a hex number. 

Do not use the built-in function eval() if all you need is to convert strings to numbers. eval() will be significantly slower and it presents a security risk: someone could pass you a Python expression that might have unwanted side effects. For example, someone could pass __import__('os').system("rm -rf $HOME") which would erase your home directory. 

eval() also has the effect of interpreting numbers as Python expressions, so that e.g. eval('09') gives a syntax error because Python regards numbers starting with '0' as octal (base 8).

Ques 38. How can my code discover the name of an object?

Generally speaking, it can't, because objects don't really have names. Essentially, assignment always binds a name to a value; The same is true of def and class statements, but in that case the value is a callable. Consider the following code:

class A:
  pass
  B = A
  a = B()
  b = a
  print b
  <__main__.A instance at 016D07CC>
  print a
  <__main__.A instance at 016D07CC>

Arguably the class has a name: even though it is bound to two names and invoked through the name B the created instance is still reported as an instance of class A. However, it is impossible to say whether the instance's name is a or b, since both names are bound to the same value.

Generally speaking it should not be necessary for your code to "know the names" of particular values. Unless you are deliberately writing introspective programs, this is usually an indication that a change of approach might be beneficial.

In comp.lang.python, Fredrik Lundh once gave an excellent analogy in answer to this question:
The same way as you get the name of that cat you found on your porch: the cat (object) itself cannot tell you its name, and it doesn't really care -- so the only way to find out what it's called is to ask all your neighbours (namespaces) if it's their cat (object)
....and don't be surprised if you'll find that it's known by many names, or no name at all!

Ques 40. How do I convert a number to a string in Python?

  • To convert, e.g., the number 144 to the string '144', use the built-in function str().
  • If you want a hexadecimal or octal representation, use the built-in functions hex() or oct().
  • For fancy formatting, use the % operator on strings, e.g. "%04d" % 144 yields '0144' and "%.3f" % (1/3.0) yields '0.333'.

Ques 41. How do I modify a string in place?

You can't, because strings are immutable. If you need an object with this ability, try converting the string to a list or use the array module:

>>> s = "Hello, world" >>> a = list(s) 
>>>print a
['H', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']

>>> a[7:] = list("there!") 
>>>''.join(a)
'Hello, there!' 

>>> import array 
>>> a = array.array('c', s) >>> print a
array('c', 'Hello, world')

>>> a[0] = 'y' ; print a
array('c', 'yello world')
>>> a.tostring()
'yello, world'

Ques 42. How do I use strings to call functions/methods in Python?

There are various techniques.

* The best is to use a dictionary that maps strings to functions. The primary advantage of this technique is that the strings do not need to match the names of the functions. This is also the primary technique used to emulate a case construct: 

def a():
  pass
  def b():
    pass
    dispatch = {'go': a, 'stop': b} # Note lack of parens for funcs
    dispatch[get_input()]() # Note trailing parens to call function

Use the built-in function getattr(): 
import foo
getattr(foo, 'bar')()

Note that getattr() works on any object, including classes, class instances, modules, and so on. This is used in several places in the standard library, like this: 

class Foo: 
  def do_foo(self):
    def do_bar(self):
      f = getattr(foo_instance, 'do_' + opname)
        f()

  • Use locals() or eval() to resolve the function name: 
    def myFunc(): print "hello" fname = "myFunc" f = locals()[fname] f() f = eval(fname) f()

Note: Using eval() is slow and dangerous. If you don't have absolute control over the contents of the string, someone could pass a string that resulted in an arbitrary function being executed. 

Is there an equivalent to Perl's chomp() for removing trailing newlines from strings? 
Starting with Python 2.2, you can use S.rstrip("\r\n") to remove all occurences of any line terminator.
from the end of the string S without removing other trailing whitespace. If the string S represents more
than one line, with several empty lines at the end, the line terminators for all the blank lines will be
removed:
>>> lines = ("line 1 "
... 
... ) 
>>> lines.rstrip(" ") 
"line 1" 
Since this is typically only desired when reading text one line at a time, using S.rstrip() this way works
well.
For older versions of Python, There are two partial substitutes:
* If you want to remove all trailing whitespace, use the rstrip() method of string objects. This removes all trailing whitespace, not just a single newline.
* Otherwise, if there is only one line in the string S, use S.splitlines()[0].
Is there a scanf() or sscanf() equivalent?
Not as such.

For simple input parsing, the easiest approach is usually to split the line into whitespace-delimited words using the split() method of string objects and then convert decimal strings to numeric values using int() or float(). split() supports an optional "sep" parameter which is useful if the line uses something other than whitespace as a separator.

For more complicated input parsing, regular expressions more powerful than C's sscanf() and better suited for the task.
