+# 🗓️ Day 13 — Iterative Statements (For Loop)
+
+## 🎯 Topics Covered
+- What is a `for` Loop?
+- Syntax of `for` Loop
+- Using `range()` Function
+- Iterating over Strings, Lists, and Tuples
+
+---
+
+## 🔁 What is a `for` Loop?
+
+- The **`for` loop** is used when you want to **iterate (repeat)** over a sequence like a list, tuple, string, or range of numbers.
+- Unlike the `while` loop (which depends on a condition), the `for` loop runs **for a specific number of iterations** or elements in a sequence.
+
+---
+
+## 🧠 Syntax:
+```python
+for variable in sequence:
+    # block of code
+```
+
+### ✅ Here:
+
+- variable → takes the value of each element from the sequence
+- sequence → can be a list, tuple, string, or range()
+
+---
+
+## 💻 Examples — Using range()
+
+The range() function generates a sequence of numbers.
+
+```python
+for i in range(1, 6):
+    print(i)
+```
+
+## 🧠 Output:
+```python
+1
+2
+3
+4
+5
+```
+
+## ✅ Explanation:
+
+- range(1, 6) → starts from 1 and stops before 6.
+- The loop executes 5 times (for 1 to 5).
+
+---
+
+## 💻 Example 2 — Iterating Over a String
+```python
+for ch in "PYTHON":
+    print(ch)
+```
+
+🧠 Output:
+```python
+P
+Y
+T
+H
+O
+N
+```
+
+> ✅ The loop goes through each character of the string "PYTHON" one by one.
+
+---
+
+## 💻 Example 3 — Iterating Over a List
+```python
+fruits = ["apple", "banana", "cherry"]
+
+for fruit in fruits:
+    print(fruit)
+```
+
+## 🧠 Output:
+```python
+apple
+banana
+cherry
+```
+
+> ✅ Each element in the list fruits is printed in order.
+
+---
+
+## 💻 Example 4 — Using range() with Step Value
+
+You can specify a step to skip numbers in between.
+```python
+for i in range(2, 11, 2):
+    print(i)
+```
+
+## 🧠 Output:
+```python
+2
+4
+6
+8
+10
+```
+
+> ✅ The loop runs from 2 to 10 with a step of 2 (even numbers only).
+

+## 🧠 Summary
+
+| Concept                    | Description                 | Example                   |
+| -------------------------- | --------------------------- | ------------------------- |
+| `for` Loop                 | Iterates through a sequence | `for x in range(5):`      |
+| `range(start, stop, step)` | Generates numbers           | `range(1, 10, 2)`         |
+| Nested Loop                | Loop inside another loop    | `for i in... for j in...` |
+| `break`                    | Stops loop immediately      | `if i==5: break`          |
+| `continue`                 | Skips current iteration     | `if i==3: continue`       |
+| `pass`                     | Does nothing (placeholder)  | `for i in range(5): pass` |
