Keep this in mind About Python Programming.
.

Computers can't store floats perfectly, in the same way that we can't
write down the complete decimal expansion of 11/3 (3.6666666666666).
Keep this in mind, because it often leads to infuriating bugs!

☑️What is Interpreter?

☑️What is Programming?

☑️Who Created Python Programming Language?

Introduction Python Programming Language.
.
Let's start, When I was learning Python the first question came in mind was, What is the Python Programming Language?

.
Python is an interpreted, high-level, general-purpose programming language.
.
let understand interpreter first, Interpreter means : it will execute your program or code one-by-one and line-by-line. and then the second question came in mind was,
.
What is the meaning of High-Level Programming Language?
.
High-Level Language means a language that is closer to human languages like English. Python one of the feature is expressive,
.
means you can express your code to the other programmer. then 3rd question came in mind was,
.
What is a Programming Language? A language that is used to give instruction to the computer to perform a task.
.
the last question came in my mind was, Who created python? It was created by Guido van Rossum.

Why does for i in range(1,3): only loop two times instead of three times in Python?

Why does for i in range(1,3): only loop two times instead of three times in Python Programming Language By DDSRY?

The range() function only does numbers from the first to the last (not including the last).
So it stop at two, not three, in the above.
This turn out to be the most common way to do this kind of loop.
