# **CustomFor - A Simple Custom Iterator**  

## **Overview**  

`CustomFor` is a lightweight Python utility that demonstrates **manual iteration** using an explicit iterator. Instead of using a traditional `for` loop, it manually retrieves elements using `next()` and applies a function to each item.  

🔹 Learn more about **Python Iterators** here: [Python Iterators](https://docs.python.org/3/tutorial/classes.html#iterators)  

## **Features**  

✅ Custom iteration over any iterable  

✅ Applies a given function to each item  

✅ Includes a built-in `capitalize` function  

## **Installation**  

No external dependencies are required. Just clone the repository and run the script.  

```bash

git clone https://github.com/YOUR-USERNAME/custom-for-loop.git

cd custom-for-loop

python custom_for.py

```

## **Usage**  

Here’s how the `CustomFor` class works:  

```python

class CustomFor:

    @staticmethod

    def iterate(iterable, func):

        iterator = iter(iterable)

        while True:

            try:

                item = next(iterator)

            except StopIteration:

                return

            else:

                func(item)

    @staticmethod

    def capitalize(item):

        print(str.capitalize(item))

def main():

    CustomFor.iterate(input("Enter your iterable: "), CustomFor.capitalize)

if __name__ == "__main__":

    main()

```

### **Example**  

#### **Input:**  

```

Enter your iterable: hello

```

#### **Output:**  

```
