# Python-Slicing 🔪🐍

Ever wondered how Python slicing works?  
What does it actually do in the background?  

This project provides a simple source code implementation that explains how slicing is done.  
The output is exactly similar to Python’s built-in slicing — but written manually to help understand the logic behind it.

---

## 🚀 How to Use

import slicer

# parameters: start, stop, step (optional)

print(slicer.slice_string(1, 3))      # string[1:3]
print(slicer.slice_string(1, 3, -1))  # string[1:3:-1]
print(slicer.slice_string(1, 3, 1))   # string[1:3:1]

If you don’t want to define the start or stop index, just pass an empty string '':

slicer.slice_string(1, '')     # string[1:]
slicer.slice_string('', '')    # string[:]
slicer.slice_string('', 3)     # string[:3]

📖 Examples

Call	Equivalent Python Slice	Output (with default string "abcdefghijklmnopqrstuvwxyz")
slice_string(1, 3)	string[1:3]	"bc"
slice_string('', '')	string[:]	"abcdefghijklmnopqrstuvwxyz"
slice_string(-1, '')	string[-1:]	"z"

⚠️ Note

• This is not a replacement for Python slicing.
• The goal is to help you analyze different slicing scenarios and answer the question: "What exactly happens when I slice a string in Python?"
• Perfect for learning, experimenting, and debugging slicing logic.
