NumPy вопросы и ответы для интервью
Вопрос 21. How to find the index of the maximum value in a NumPy array?
You can use 'np.argmax()'. For example, 'np.argmax(arr)' returns the index of the maximum value in 'arr'.
Вопрос 22. What is the purpose of 'np.where()' in NumPy?
'np.where()' returns the indices of elements that satisfy a given condition.
Вопрос 23. Explain the use of 'np.linalg.inv()' in NumPy.
'np.linalg.inv()' computes the (multiplicative) inverse of a matrix.
Вопрос 24. How to find the shape of a NumPy array?
You can use the attribute 'shape'. For example, 'arr.shape' returns the shape of 'arr'.
Вопрос 25. What is the purpose of 'np.eye()' in NumPy?
'np.eye()' creates an identity matrix with ones on the main diagonal and zeros elsewhere.
