Description

The isdigit() method checks whether a string consists of only digits.

Syntax

The syntax of the isdigit() method is as follows:

var.isdigit()

Return Value

This method returns True if all characters in the string are digits. It returns False if at least one character is not a digit (0-9).

Example

The following example demonstrates the use of the isdigit() method.

var = "500081"
var1 = var.isdigit()
print("Original string:", var)
print("Does it contain only digits?:", var1)

var = "TutorialsPoint"
var2 = var.isdigit()
print("Original string:", var)
print("Does it contain only digits?:", var2)

var = "123.34"
var3 = var.isdigit()
print("Original string:", var)
print("Does it contain only digits?:", var3)

When you run this program, it will produce the following output −
