NumPy: Check two random arrays are equal or not

NumPy: Random Exercise-10 with Solution

Write a NumPy program to check two random arrays are equal or not.

Sample Solution:

Python Code :

import numpy as np
x = np.random.randint(0,2,6)
print("First array:")
print(x)
y = np.random.randint(0,2,6)
print("Second array:")
print(y)
print("Test above two arrays are equal or not!")
array_equal = np.allclose(x, y)
print(array_equal)

Sample Output:

First array:                                                           
[1 0 0 0 1 0]                                                          
Second array:                                                          
[0 0 1 1 0 1]                                                          
Test above two arrays are equal or not!                                
False

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
