In this source code example, we will demonstrate how to use the Python string isnumeric() method to check if all characters in a string are numeric characters.

Use the Python string isnumeric() to determine if all characters in a string are numeric characters.

Python string isnumeric() method example

The following example uses the isnumeric() method to determine if all characters are numeric characters:

amount = '123'
result = amount.isnumeric()

print(result)

Output:

True

The following example returns False as input characters are not a numeric:

price = '99.99'
print(price.isnumeric())

discount = '-10'
print(discount.isnumeric())

Output:

False
False
