Python - check if string only contains numbers
0 points
In this article, we would like to show you how to check if string only contains numbers in Python.
Quick solution:
xxxxxxxxxx1
text = "123"2
print(text.isdigit()) # Truexxxxxxxxxx1
text = "123a"2
print(text.isdigit()) # False
In this example, we use string.isdigit() method to check if the strings contain only numbers.
xxxxxxxxxx1
numbers = "123"2
print(numbers.isdigit()) # True3
4
text = "abc"5
print(text.isdigit()) # False6
7
float_number = "1.23"8
print(float_number.isdigit()) # FalseOutput:
xxxxxxxxxx1
True2
False3
FalseNote:
You can also use
isdecimal()instead ofisdigit().
