# How to debug Python (Django) using `breakpoint()` function?

# Introduction:

**Debugging** is the skill which I feel very few do it perfectly. But it is a must-have skill for every **programmer**.

In **Python**, you can easily **debug** your **code** with the help of python’s `breakpoint()` ***function***.

***Note:*** There are other ways to **debug** your **Python** code, the most common way is to use your **IDE’s** **debugger** such as **PyCharm**. **VSCode** also comes with a great built-in **debugger**.

# Let’s do it:

**Debugging** starts by creating a breakpoint.

- Create a **breakpoint** by inserting the `breakpoint()`  ***function*** just before the suspected line.

```python
a = 1
b = 0
breakpoint()
c = a/b  # ZeroDivisionError
```

- Whenever the ***Python interpreter*** hits this `breakpoint()` method, it will pause the ***execution*** and wait for your response in the **terminal**.
- In the **terminal**, you have a **Python** shell like interface called '***pdb shell'***, where you can access all the ***variables***, ***function***, etc. of the current **execution context**.
- There are some shortcut keys for navigating in the ‘***pdb shell***’. For listing all the shortcuts, you can use help command by entering **`h`.**

***Note:*** *`breakpoint()` only works above **Python 3.7**, to debug on older versions of Python, you should use '**pdb** 'module as given in below example.*

```python
import pdb

a = 1
b = 0
pdb.set_trace()
c = a/b  # ZeroDivisionError
```
