Python random number/Python random string-related code parsing

The following article introduces the application of Python random number and Python random string in the form of code in practical application. The following is a detailed introduction of the article, let's share it with you!

Python random number and random string

 
 

  
  
>>> 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 Python random character strings among multiple characters:

 
 

  
  
>>> 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] 
 
 

The above article introduces the actual application code of Python random number and Python random string.
