# HOFU

A simple, fast and lightweight HOF (higher order functions) library for python.

This library allows you to use HOFs in a simple way, comparable to JavaScript its HOF and the Rust iterator.

## Installation

```bash
pip install hofu
```

### Example

```py
from hofu import Iterator

Iterator(range(10)) \
    .map(lambda x: x ** 2) \
    .filter(lambda x: x % 2 == 0 and x != 0) \
    .map(lambda x: "Next even power is " + str(x)) \
    .for_each(print)

# +- equivalent to sum(range(10))
total = Iterator(range(10)).reduce(lambda x, y: x + y)
print("Sum of 1-10:", total)

Iterator(range(10)) \
    .rev() \
    .skip(5) \
    .take(2) \
    .map(lambda x: "Next number: " + str(x)) \
    .for_each(print)

people = [
    {"name": "John", "age": 30},
    {"name": "Jane", "age": 25},
    {"name": "Bob", "age": 40},
    {"name": "Alice", "age": 35},
]
average_age = Iterator(people).reduce(lambda x, y: x + y["age"], 0) / len(people)
print("Average age:", average_age)

data = Iterator(range(10)).filter(lambda x: x % 2 == 0).collect()
print("Even numbers:", list(data))

even_formatted = Iterator(range(10)).map(lambda x: f"{x}={'even' if x % 2 == 0 else 'odd'}").collect()
print("Even/odd:", list(even_formatted))
```
