NumPy Questions et reponses d'entretien
Question 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'.
Question 22. What is the purpose of 'np.where()' in NumPy?
'np.where()' returns the indices of elements that satisfy a given condition.
Question 23. Explain the use of 'np.linalg.inv()' in NumPy.
'np.linalg.inv()' computes the (multiplicative) inverse of a matrix.
Question 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'.
Question 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.
