Are there any functions that check wether a variable is an integer or not?

Question

a = ”hello”
b = a.isalpha()
print(b)
The output will be True
I need a function similar to isalpha() to check wether the variable is an integer or not.

Answer 1

Jay Matthews I mean for a variable with an actual integer not numbers within a string.
a = 200
b = a.something()
print(b)
Output: True
