NumPy: Get the numpy version and show numpy build configuration

NumPy: Basic Exercise-1 with Solution

Write a NumPy program to get the numpy version and show numpy build configuration.

Sample Solution :

Python Code :

import numpy as np
print(np.__version__)
print(np.show_config())

Sample Output:

lapack_opt_info:
    library_dirs = ['C:\\projects\\numpy-wheels\\numpy\\build\\openblas']
    define_macros = [('HAVE_CBLAS', None)]
    libraries = ['openblas']
    language = f77
blis_info:
  NOT AVAILABLE
blas_opt_info:
    library_dirs = ['C:\\projects\\numpy-wheels\\numpy\\build\\openblas']
    define_macros = [('HAVE_CBLAS', None)]
    libraries = ['openblas']
    language = f77
openblas_lapack_info:
    library_dirs = ['C:\\projects\\numpy-wheels\\numpy\\build\\openblas']
    define_macros = [('HAVE_CBLAS', None)]
    libraries = ['openblas']
    language = f77
openblas_info:
    library_dirs = ['C:\\projects\\numpy-wheels\\numpy\\build\\openblas']
    define_macros = [('HAVE_CBLAS', None)]
    libraries = ['openblas']
    language = f77
blas_mkl_info:
  NOT AVAILABLE
lapack_mkl_info:
  NOT AVAILABLE
None

Python: Tips of the Day

Merges two or more lists into a list of lists, combining elements from each of the input lists based on their positions

Example:

def tips_merge(*args, fill_value=None):
  max_length = max([len(lst) for lst in args])
  result = []
  for i in range(max_length):
    result.append([
      args[k][i] if i < len(args[k])
	  else fill_value for k in range(len(args))
    ])
  return result
print(tips_merge(['x', 'y'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False], fill_value = '_')) 

Output:

[['x', 1, True], ['y', 2, False]]
[['x', 1, True], [None, 2, False]]
[['x', 1, True], ['_', 2, False]]
