Correct Answer : Option (A) :   Numerical Python

Explanation : NumPy, which stands for Numerical Python, is a library consisting of multidimensional array objects

Correct Answer : Option (C) :   Travis Oliphant

Correct Answer : Option (D) :   All of the above

Correct Answer : Option (D) :   Both B and C

Explanation : NumPy is often used along with packages like SciPy (Scientific Python) and Matplotlib (plotting library)

Correct Answer : Option (D) :   All of the mentioned

Explanation : NumPy is the fundamental package for scientific computing with Python.

Correct Answer : Option (B) :   ix_

Explanation : Length of the 1D boolean array must coincide with the length of the dimension (or axis) you want to slice.

Correct Answer : Option (C) :   setbufsize(size)

Explanation : Adjusting the size of the buffer may therefore alter the speed at which ufunc calculations of various sorts are completed.

Correct Answer : Option (A) :   .types

Explanation : Universal functions in NumPy are flexible enough to have mixed type signatures.

Correct Answer : Option (A) :   column_stack

Explanation : column_stack is equivalent to vstack only for 1D arrays.

Correct Answer : Option (B) :   reshape, resize

Explanation : If a dimension is given as -1 in a reshaping operation, the other dimensions are automatically calculated.
