Random INTEGER:
Copy codeThe Code is as follows:
>>> Import random
>>> Random. randint (0, 99)
21

Randomly select an even number between 0 and 100:
Copy codeThe Code is as follows:
>>> Import random
>>> Random. randrange (0,101, 2)
42

Random Floating Point Number:
Copy codeThe Code is as follows:
>>> Import random
>>> Random. random ()
0.85415370477785668
>>> Random. uniform (1, 10)

Random characters:
Copy codeThe Code is as follows:
>>> Import random
>>> Random. choice ('abcdefg & # % ^ * F ')

Eplace ("","")
'Fih'

'Limon'

Shuffling:
Copy codeThe Code is as follows:
>>> Import random
>>> Items = [1, 2, 3, 4, 5, 6]
