Python String isdecimal() Method

The isdecimal() method is a string method that returns True if all the characters in the string are decimal characters (0-9).

For example:


num = "123"
print(num.isdecimal())

# prints True

The method returns False if the string contains any non-decimal characters, such as letters, spaces, punctuation marks, symbols, etc.

For example:

num = "12.3"
print(num.isdecimal())

# prints False
