Python - check if string contains only digits

In this article, we would like to show you how to check if string contains only digits in Python.

Quick solution:

text = "123"
print(text.isdigit())  # True

text = "123a"
print(text.isdigit())  # False

Practical example

In this example, we use string.isdigit() method to check if the strings contain only digits.

numbers = "123"
print(numbers.isdigit())  # True

text = "ABC"
print(text.isdigit())  # False

float_number = "1.23"
print(float_number.isdigit())  # False

Output:

True
False
False

Note:

You can also use isdecimal() method instead of isdigit().
