In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

# Bit operators overview

The following **bit operators** may be applied to integers.

| **Bit Operator**  | **Description**  |
|---|---|
| `~`  | Bitwise complement  |
| `&`  | Bitwise and |
| `|`  |  Bitwise or |
| `^`  |  Bitwise exclusive or |
| `<<`  |  Left shift |
| `>>`  |  Right shift |

In case you are unfamiliar with these operators, each number is used in its binary notation, with `0` consisting of all zero bits, and `-1` consisting of all one bits.

# Bitwise complement (`~`)

**Bitwise complement** changes every 1 to a 0 and every 0 to a 1. Numerically, the result is the same as changing the sign of the number and then subtracting 1.

For example, in the following example, when the `~` operator is applied on the integer **50**, we get **-51**.This is because the bitwise complement first changes the sign of **50**,  making it negative, and then subtracts **1** from it, adding the two negative integers together to give **-51**. 

You'll learn about the different bit operators present in Python in this lesson.

Bit Operator	Description
`~`	Bitwise complement
`&`	Bitwise and
`\|`	Bitwise or
`^`	Bitwise exclusive or
