First-time poster and very new to Python and programming in general. I have been working on a character creator project and I'm trying to figure out how to deal with a non-integer being typed in for one of the attributes prompts, like "int(input('Strength: ')),"

I want to prevent a crash from the user typing in something other than an integer, and then to prompt the user to input the specific attribute again.

Here's a chunk of the code that I'm talking about.

class Char_presets:
    def __init__(self, name, type, strength, dexterity, wisdom, intelligence, faith):
        self.name = name
        self.type = type
        self.strength = strength
        self.dexterity = dexterity
        self.wisdom = wisdom
        self.intelligence = intelligence
        self.faith = faith

def create_clss():
    c1 = input('Save name?: ')

    c1 = Char_presets(
        input("What is your name?: "),
        input('Class type?: '),
        int(input('Strength: ')),
        int(input('Dexterity: ')),
        int(input('Wisdom: ')),
        int(input('Intelligence: ')),
        int(input('Faith: '))
    )

Thanks for any help.

Determine if the input string is an integer or not, and continue asking if not.

strength = input("Strength: ")

while not strength.isnumeric():
    strength = input("That's not an integer! Strength: ")

# at this point, strength will contain an integer

You can utilize the walrus operator introduced in python 3.9:

def create_clss():
    c1 = input('Save name?: ')
    while (strength := input('Strength: ')): # strength is defined here!
        if strength.isdigit(): # check if the input is all digits
            break
    c1 = Char_presets(
        input("What is your name?: "),
        input('Class type?: '),
        int(strength),
        int(input('Dexterity: ')),
        int(input('Wisdom: ')),
        int(input('Intelligence: ')),
        int(input('Faith: '))
    )
