The easiest way to check if a number is a whole number in Python is using the **is_integer()** function.

```
print((2.0).is_integer())
print((2.01).is_integer())
#Output:
True
False
```

You can also check if the number minus the integer conversion of the number is equal to 0.

```
print(2.0 - int(2.0) == 0)
print(2.01 - int(2.01) == 0)
#Output:
True
False
```

In Python, when working with numbers, it can be useful to be able to find out if a number is a whole number.

We can easily check if a number is a whole number with the help of the float is_integer() function.

The **is_integer()** function returns a boolean indicating if the float is an integer or not.

Below are some examples of how to use the Python **is_integer()** function to check if a number is a whole number.

```
print((2.0).is_integer())
print((2.01).is_integer())
#Output:
True
False
```

## Checking if a Number is a Whole Number Using Integer Conversion in Python

You can also check if a number is a whole number using integer conversion in Python. If we convert a floating point number to an integer, then the difference between the number and the newly created integer should be 0 if the number is a whole number.

Below are some examples of how you can use integer conversion to check if number is whole.

```
print(2.0 - int(2.0) == 0)
print(2.01 - int(2.01) == 0)
#Output:
True
False
```
