Random

Generate Random variables

Generates a random number of [0, 1) . Random

Import Randomrandom_number = Random.random () print (random_number) print (Random_number + 1)

Generates a [start, end] random number . Uniform

Import randomrandom_number = Random.uniform (0, ten) print (Random_number)

Generates a [start, end] interval random integer . Randint

Import Randomrandom_number = Random.randint (1, ten) print (Random_number)

Generate (start, end) interval random integer randrange

Import Randomrandom_number = Random.randrange (1, ten) print (Random_number)

Randomly take a value from a sequence choice

Import randomrandom_sequence = Random.choice (["1", "2", "3"]) print (random_sequence)

Sampling sample randomly from a sequence

Import randomtarget_str = "0123456789abcdefghijklmnopqrstuvwxyz" random_sequence = Random.sample (target_str, 6) print ( Random_sequence) # 6-digit random verification code print (". Join (Random_sequence))

Arithmetic Operation Verification Code implementation

Import randomnumber_str = "123456789" letter_str = ' abcdefghijklmnopqrstuvwxyz ' operator = "+-x" RANDOM_STR = Random.choice (NUMBER_STR) + random.choice (operator) +              Random.choice (number_str) + random.choice (operator) +              Random.choice (number_str) print (Random_str.replace (' x ', ' * ')) print (eval (random_str.replace (' x ', ' * ')))
