Python is a powerful, easy-to-learn programming language that is widely used in web development, data analysis, artificial intelligence, and more. In this beginner’s guide, we’ll cover the basics of the Python language, including data types, variables, loops, and functions.

Let us begin.

Data Types

Python has a number of built-in data types, including integers (whole numbers), floats (decimal numbers), strings (text), and booleans (True or False values). Here is an example of data types in Python:

# integers
x = 5
print(x) # Output: 5

# floats
y = 3.14
print(y) # Output: 3.14

# strings
z = "hello"
print(z) # Output: hello

# booleans
a = True
print(a) # Output: True

Variables

In Python, you can assign values to variables using the assignment operator (=). Once a value is assigned to a variable, you can use that variable to access the value. Here’s an example:

x = 5
print(x) # Output: 5
x = 10
print(x) # Output: 10
