Day 5: Forgetting Indentation

 

🐍 Python Mistakes Everyone Makes ❌

Day 5: Forgetting Indentation

Python treats indentation as part of the language syntax.
Forgetting it can cause your code to fail immediately.

---

❌ The Mistake

if True:
print("Hello")

---

❌ Why this fails?

Because Python uses indentation to define code blocks.

Without proper indentation, Python cannot understand which lines belong inside the if statement, resulting in an IndentationError.

---

✅ The Correct Way

if True:
    print("Hello")

✔ Indentation clearly shows the block structure
✔ Python code now runs correctly

---

🧠 Simple Rule to Remember

• Indentation is syntax, not style

• Use 4 spaces per indentation level

• Be consistent don’t mix tabs and spaces
