Random.random () / / generate a random number between 0 and 1

Random.randint (1BME 5) / / generates integers between 1 and 5, including 1 and 5, in the range: [1-5]

Random.randrange (1d10) / / generates integers between 1 and 10, including 1, but excluding 10

Example: generate a 6-digit random CAPTCHA, including numbers and letters

Code = []

For i in range (6):

If I = = random.randint (1BI 5):

Code.append (str (random.randint (1pm 5)

Temp = random.randint (655.90)
