Python Quiz #45 Fix the Bug in Python: A Coding Challenge | Python for Beginners | while loop

In this video, we dive into a common mistake made when using the `continue` statement inside a `while` loop in Python. We'll walk you through a scenario where the loop is supposed to print numbers from `0` to `4`, skipping the number `2`, but instead ends up in an infinite loop. We'll explain why this happens and how to fix the code so it runs smoothly. By the end of the video, you'll learn how to avoid this common pitfall in Python loops. Perfect for Python beginners or anyone looking to solidify their understanding of loops in Python.

**Key Points Covered:**
- Understanding `continue` in `while` loops
- Identifying and fixing infinite loops
- Debugging common Python loop issues

Corrected code provided with clear explanations to help you code more efficiently and avoid infinite loops!

**Scenario:**
You are tasked with debugging a piece of Python code that uses a `while` loop. The goal of the loop is to print numbers from `0` to `4`, skipping the number `2`. However, the code as written enters an infinite loop when the value of `i` becomes `2`.

**Given Code:**
```python
i = 0

while i < 5:
if i == 2:
continue
print(i)
i += 1
```

**Problem:**
The `continue` statement is misused in this code. When `i == 2`, the `continue` statement is executed, causing the loop to skip the `i += 1` statement. As a result, `i` remains `2` indefinitely, leading to an infinite loop.

**Task:**
1. Identify the mistake in the code that causes the infinite loop.
2. Correct the code so that it successfully prints all numbers from `0` to `4`, except for `2`.

**Expected Output:**
```
0
1
3
4
```

The problem is, that continue skips the rest of the code, including i += 1. A solution would be to increase i by one in the if statement

i = 0

while i < 5:
if i == 2:
i += 1
continue
print(i)
i += 1
