How to limit the type of characters input python
How can I limit the number of characters and type of characters that can be inputted.
s = input('What is your number)
a number can only be 9 digits so it should be limited to 9 digits and only numbers
x = input('what is your email address)
an email address can contain a minimum of 8 characters and a maximum of 60 characters and also must contain an @ symbol.
How would I go about doing this?
python limit

You can not limit the input while the user is typing. You will have to take the input, check it and reprompt if it fails the check.

In fact, my dear friend, you cannot limit input function, but you can achieve what you want by this way:
def isnumber(s):
if s.isdigit() and len(s) <= 9:
return True
else:
print('you should input number and length less than 9')
return False
def main():
s = input('What is your number')
while not isnumber(s):
s = input('What is your number')
print("your number is", s)
if __name__ == "__main__":
main()
Thank you!!!!!!
