Python random number and random string

Random integer: & gt; importrandom & gt; randomrandint (100) 21: an even number ranging from 0 to: & gt; & gt; importrandom & gt; randomrandrange (0,101, 2) 42 random floating point 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 randomrandom.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)).replace(" ","")'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]

There are still many random functions, which are not listed here,
