# Logical and Bitwise NOT Operators on Boolean in Python

Python | Logical and Bitwise Not Operators: Here, we are going to learn how logical NOT (not) and Bitwise NOT (~) operators work with Boolean values in Python?

In python, not is used for Logical NOT operator, and ~ is used for Bitwise NOT. Here, we will see their usages and implementation in Python.

Logical NOT (not) operator is used to reverse the result, it returns "False" if the result is "True"; "True", otherwise.

Bitwise NOT (~) operator is used to invert all the bits i.e. it returns the one's complement of the number.

Python program of Logical NOT (not) operator

```# Logical NOT (not) operator

x = True
y = False

# printing the values
print("x: ", x)
print("y: ", y)

# 'not' operations
print("not x: ", not x)
print("not y: ", not y)
```

Output:

```x:  True
y:  False
not x:  False
not y:  True
```

Python program of Bitwise NOT (~) operator

```# Bitwise NOT (~) operator

x = True
y = False

# printing the values
print("x: ", x)
print("y: ", y)

# '~' operations
print("~ x: ", ~ x)
print("~ y: ", ~ y)

# assigning numbers
x = 123
y = 128

# printing the values
print("x: ", x)
print("y: ", y)

# '~' operations
print("~ x: ", ~ x)
print("~ y: ", ~ y)
```

Output:

```x:  True
y:  False
~ x:  -2
~ y:  -1
x:  123
y:  128
~ x:  -124
~ y:  -129
```
