This:

import random

def main():

        userNumber1 = input("Choose a number from 1-20")
        userNumber2 = input("Choose another number from 1-20")
    if (userNumber1 == userNumber2):
        print("Invalid input")
    else:
        num1 = random.Random(userNumber1,userNumber2)
        num2 = random.Random(userNumber1,userNumber2)
        num3 = random.Random(userNumber1,userNumber2)
    while (num1==num2 or num1==num3 or num3==num2):
        if (num3==num2):
            del num2
            num2 = random.Random(userNumber1,userNumber2)
        elif (num1==num3):
            del num3
            num3 = random.Random(userNumber1,userNumber2)
        elif (num1==num2):
            del num2
            num2 = random.Random(userNumber1,userNumber2)
        else:
            pass
    print(str(num1) str(num2) str(num3))
main()

is giving back the error:

TypeError: __init__() takes from 1 to 2 positional arguments but 3 were given

Does anyone know why and help me troubleshoot?

CodePudding user response：

random.Random is a class. You construct an instance of it if you want your own random number generator based on a given seed or a given algorithm.

It looks like you're simply trying to construct some random integers in a range, so you're looking for randint.

random.randint(a, b)

Return a random integer N such that a <= N <= b. Alias for randrange(a, b 1).

Note that the bounds are inclusive, so a and b are valid returns from this function. Adjust your bounds as needed if that's not intentional.

CodePudding user response：

If you're trying to generate random numbers between the user input bounds, the function you're looking for is random.randint:

r = random.randint(3, 12)    # -> returns a random integer 3 <= r < 12

CodePudding user response：

Use random.randint() instead of random.Random()

CodePudding user response：

First of all indent user Inputs 1 tab backwards,from the look of it you are trying to get a random no between user inputs for this purpose use Random.randint here is the error free code .

import random

def main():

    userNumber1 = int(input("Choose a number from 1-20"))
    userNumber2 = int(input("Choose another number from 1-20"))
    if userNumber1 == userNumber2:
        print("Invalid input")
    else:
        num1 = random.randint(userNumber1,userNumber2)
        num2 = random.randint(userNumber1,userNumber2)
        num3 = random.randint(userNumber1,userNumber2)
    while (num1==num2 or num1==num3 or num3==num2):
        if (num3==num2):
            del num2
            num2 = random.randint(userNumber1,userNumber2)
        elif (num1==num3):
            del num3
            num3 = random.randint(userNumber1,userNumber2)
        elif (num1==num2):
            del num2
            num2 = random.randint(userNumber1,userNumber2)
        else:
            pass
    print(str(num1) str(num2) str(num3))
main()
