# Example 1: Using a for loop to iterate through a list
colors = ["red", "green", "blue"]
for color in colors:
    print("Color:", color)

# Example 2: Using a for loop with range()
for i in range(1, 4):
    print("Number:", i)

# Example 3: Using a while loop
counter = 1
while counter <= 3:
    print("Counter:", counter)
    counter += 1

# Loops: `for` and `while`

In programming, we often need to repeat actions — such as printing items, summing values, or checking conditions. Loops allow us to do this efficiently without rewriting the same code.

Python provides two main types of loops: `for` and `while`.

<br/>

## `for` Loops

A `for` loop is used when you want to go through each item in a sequence, such as a list, string, or range of numbers.

```python title="For Loop"
fruits = ["apple", "banana", "cherry"]

for fruit in fruits:
    print("I like", fruit)
```

### Explanation

* `fruits` is a list.
* The variable `fruit` takes one value from the list in each loop.
* The loop prints a sentence using that value.
* This repeats three times, once for each fruit.

<br/>

## `while` Loops

A `while` loop runs **as long as a condition is true**.

```python title="While Loop"
count = 1

while count <= 3:
    print("Count is:", count)
    count += 1
```

### Explanation

* The loop starts with `count = 1`.
* It checks the condition `count <= 3`. If it is true, the block runs.
* After each loop, `count` increases by 1.
* When `count` becomes 4, the condition is false and the loop stops.

<br/>

## When to Use Each

* Use a `for` loop when you already know the collection of items you want to process.
* Use a `while` loop when the number of repetitions depends on a condition that can change over time.

A `while` loop is not typically used for iterating over a known sequence of items; that's where a `for` loop excels. The `while` loop is designed to run as long as a specific condition remains true, making it ideal for situations where the number of iterations isn't predetermined.

### In Python, a `while` loop is useful when you need to iterate over a known sequence of items.
