Sample Code for the python Random Number Module

Python Random Number Module

If you know python, do you know the random number module in python? If you do not know much about the python Random Number Module, you can read the following articles to learn about it.

Random INTEGER:

 
 

  
  
>>> import random  
  
  
>>> random.randint(0,99)  
  
  
21 
 
 

Randomly select an even number between 0 and 100:

 
 

  
  
>>> import random  
  
  
>>> random.randrange(0, 101, 2)  
  
  
42 
 
 

Random Floating Point Number:

 
 

  
  
>>> import random  
  
  
>>> random.random()   
  
  
0.85415370477785668  
  
  
>>> random.uniform(1, 10)  
  
  
5.4221167969800881 
 
 

Random characters:

 
 

  
  
>>> import random  
  
  
>>> random.choice('abcdefg&#%^*f')  
  
  
'd' 
 
 

Select a specific number of characters from multiple characters:

 
 

  
  
>>> import random  
  
  
random.sample('abcdefghij',3)   
  
  
['a', 'd', 'b'] 
 
 

Select a specific number of characters to form a new string:

 
 

  
  
>>> import random  
  
  
>>> import string  
  
  
>>> string.join(random.sample(['a','b','c','d','e','f','g','h','i','j'], 3)).r  
  
  
eplace(" ","")  
  
  
'fih' 
 
 

Randomly selected string:

 
 

  
  
>>> import random  
  
  
>>> random.choice ( ['apple', 'pear', 'peach', 'orange', 'lemon'] )  
  
  
'lemon' 
 
 

Shuffling:

 
 

  
  
>>> import random  
  
  
>>> items = [1, 2, 3, 4, 5, 6]  
  
  
>>> random.shuffle(items)  
  
  
>>> items  
  
  
[3, 2, 5, 6, 4, 1]
