# 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 let us do this efficiently without writing the same code multiple times.

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 set of items you want to process.
* Use a `while` loop when the number of repetitions depends on a condition that may change.

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.
