Python Programming Guide.
Introduction:
Python is a general-purpose, interpreted, high-level programming language that has become
popular among developers for its simplicity, ease of use, and versatility. In this guide, we'll cover
the basics of Python programming, from installation and setting up the environment to working
with variables, data types, and control structures.
Part 1: Setting Up Environment and Installation:
Before diving into Python programming, we need to set up our environment. Here are the steps
to do so:
Download the latest version of Python from the official website.
(https://www.python.org/downloads/)
Follow the installation wizard and choose the appropriate options.
Add Python to the PATH environment variable.
Install a code editor, such as Visual Studio Code, PyCharm, or Sublime Text.
Part 2: Python Basics:
Now that we have our environment set up, let's start with the basics of Python programming.
Hello World:
To get started, let's create a simple "Hello World" program:
python
Copy code
print("Hello, World!")
Variables and Data Types:
Python has several built-in data types, including integers, floating-point numbers, strings,
booleans, and lists. Here's an example of how to use variables and data types in Python:
makefile
Copy code
# integers
a=5
b = 10
c=a+b
# floating-point numbers
d = 1.23
e = 4.56
f=d+e
# strings
g = "Hello"
h = "World"
i=g+""+h
# booleans
j = True
k = False
# lists
l = [1, 2, 3, 4, 5]
m = ["apple", "banana", "cherry"]
Control Structures:
Python supports various control structures, including if/else statements, for loops, and while
loops. Here's an example of each:
python
Copy code
# if/else statement
x = 10
if x > 5:
print("x is greater than 5")
else:
print("x is less than or equal to 5")
# for loop
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
