This is the first part of a complete Python tutorial series by SRJahir Tech. In this part, we will build the foundation — not syntax dumping. Before writing real code, you must understand what Python is, why it exists, and where it is actually used.
Python is a high-level programming language designed to be readable, simple, and powerful. It allows humans to express logic in a way that looks close to plain English.
Python is not slow or weak — it is intentionally designed to prioritize clarity and productivity. Behind the scenes, Python is backed by highly optimized systems written in C.
Let us start with the most basic program. This is not magic — this is simply telling the computer to display text.
print("Hello, Python!")
Explanation:
print() is a built-in function.
It sends output to the screen.
Python reads your code line by line from top to bottom. It does not guess. It does exactly what you instruct — nothing more, nothing less.
Open terminal or command prompt and type:
python --version
If Python is installed correctly, you will see the version number.
Do not rush. Python rewards people who understand logic, not people who copy code blindly.
In the next part, we will understand variables, data types, and how Python stores information in memory.
