We’ve listed below two different ways to check whether variable contains integer value or not.
- Using
type()function- It accepts operand(variable or value) as an argument and return it’s data-type.
- Return value can be used to with
intclass.
- Using
isinstance()function- We pass first argument as operand(variable or value) and second argument as
intclass.
- We pass first argument as operand(variable or value) and second argument as
In this article we’ll see how to check if a variable is an integer. Let us understand also with an example.
Check Python variable is of an integer type or not
Method 1 using type() function
Passing the variable as an argument, and then comparing the result to the int class.
age = 12
type(age) == int
# True
age = 12.24
type(age) == int
# False
age = '12.24'
type(age) == int
# FalseMethod 2 using isinstance() function
Passing variable as first argument, and int class as second argument.
age = 12
isinstance(age, int)
# True
age = 12.24
isinstance(age, int)
# False
age = '12.24'
isinstance(age, int)
# FalseEven comparing float type of value with int class, either by using type() or isinstance() function, will give False as resultant value. Same for value '12.24' enclosed in single quotes.
