Now we’re gonna teach you to use the isnumeric() method in Python.
Example
Example 1:

True
Example 2:
str = "-2" x = str.isnumeric() print(x)

More examples
Example 1:
str1 = "-1" print(str1.isnumeric()) str2 = "7347" print(str2.isnumeric()) str3 = "83jj38" print(str3.isnumeric())
Output:
False
True
False
Example 2: Combining input() function
print("Enter the string:")
x = input().isnumeric()
print(x)
Output:
Enter the string: 32324
True
