NumPy вопросы и ответы для интервью
Вопрос 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.
Вопрос 12. Create a diagonal matrix using NumPy.
import numpy as npnarr = np.diag([1, 2, 3])
Вопрос 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.
Вопрос 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'.
Вопрос 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.
