Rand Function In Numpy






Purpose





Syntax


random.rand([number1, number 2….])




  1. Input parameter is optional.
  2. If no input parameter is passed, then function will return a single number between 0 and 1.
  3. If 1 parameter is passed, then function will return a single dimensional array (all the values are between 0 and 1). Number of items in an array is equal to the value passed as parameter.
  4. If 2 parameters are passed, then function will return a two-dimensional array (all the values are between 0 and 1) and so on.
  5. The output will be a floating point number.

Example


import numpy as np

print("No value is passed - ",np.random.rand())
print("One value is passed - ",np.random.rand(2))
print("Two values are passed - ",np.random.rand(2,2))
