NumPy Interviewfragen und Antworten
Frage 11. Explain the differences between np.dot() and np.matmul() in NumPy.
np.dot() performs matrix multiplication for 2-D arrays, while np.matmul() is equivalent to the '@' operator and is more general.
Frage 12. Create a diagonal matrix using NumPy.
import numpy as npnarr = np.diag([1, 2, 3])
Frage 13. Explain the purpose of np.meshgrid() in NumPy.
np.meshgrid() is used to create coordinate matrices from coordinate vectors, commonly used for 3D plotting.
Frage 14. How to find the dimension of a NumPy array?
You can use the attribute 'ndim'. For example, if 'arr' is your array, use 'arr.ndim'.
Frage 15. What is the difference between 'np.zeros()' and 'np.ones()' in NumPy?
'np.zeros()' creates an array filled with zeros, while 'np.ones()' creates an array filled with ones.
