How to input numbers

Since you guys are better than me do you mind telling me how to put a code for when I put in a command for it only to accept numbers

You can surround a casted input statement with a try - except block and a loop that just does another input if the cast fails.

Thank you I will try that

Hey I had to run an errand do you mind showing me what it should look like hope u r still on

Nvm I found out 🙏🏾 for ur help tho

You can als do this:


number = input("Enter a number")
if number.isdigit():#If the input is a number:
    print("yay")
else:
    print(":( i wanted a number")

Of course you can loop it and stuff but that is the foundation


while True:
s1 = input('number goes here')
try: int(s1)
except: 
print('pls enter a NUMBER')
else:
[*insert rest of code here*]

Because it doesn’t say error when I don’t put numbers
