Random

　　Random characters are needed in many parts of our program, and we can generate random strings from the randomness module.

Common methods are as follows:

ImportRandomImportstring#returns a random number between 1-10, excludingPrint(Random.randrange (1, 10))#returns a random number between 1-10, including tenPrint(Random.randint (1, 10))#returns a random floating-point numberPrint(Random.random ())#returns a random character for a specified data collectionPrint(Random.choice ("Hello,world"))#returns the specified number of returns for a given stringPrint(Random.sample ("Hello,world", 3))#Generate random strings ="". Join (Random.sample (String.ascii_lowercase + string.ascii_uppercase, 5))Print(s)
