Random number of modules random_python

A random number random module

　1, several commonly used methods:

Random Import 
Print ( random.random () ) # random number between [0,1], as 0.6772275352932792 
Print ( the random.randint (2,89) ) # random number between two parameters 
Print ( The random.choice ( 'Hello') ) # parameters from inside random h 
Print ( random.sample ([1,2,3,4],. 3) ) # randomly specified number in the list, such as [2,. 1,. 3] 
list = [1,2,3,4] 
Print ( random.shuffle (list) ) # randomly shuffled list, direct change list, returns empty 
Print (list) # [. 3,. 4, 2,. 1] 
Print ( random.randrange (1,5) ) # a random integer in the range, not including five 

2, example: random 5-bit codes generated
 randomly generated numbers 5:

v_code DEF (): 
    code = '' 
    for I in Range (0,5): 
        add_num = random.randrange (10) 
        code = + STR (add_num) 
    Print (code) 
v_code () 

randomly generate five letters or numbers:

v_code DEF (): 
    code = '' 
    for I in Range (. 5): 
        the Add = The random.choice ([random.randrange (10), CHR (random.randrange (65,91))]) # 0-9 comprises, capital letters AZ, 5 personal digital random 
        code = + STR (the Add) 
    Print (code)
