Check if a Python float is an integer

2.4 is a float and not an integer. 3.0 is a float and can be regarded as an integer because 3.0 is the same as 3. A Python float has the method to check if it can be an integer or not.

a = 1.5.is_integer()
b = 2.0.is_integer()

print(a)  # False
print(b)  # True

A float object has the is_integer() method that returns a boolean value, true or false. If the value can be an integer, the method returns true. An integer doesn't have this method.

a = 1.is_integer()
# SyntaxError: invalid syntax

In Python, 1 is int and 1.0 is float.
