Python Basics

Python Basics is the foundation of Python programming. In this module, you will learn how Python stores data, performs operations, works with text, and communicates with the user.

CIIT Training Institute : This module is designed to build a strong Python programming foundation before moving toward control flow, functions, OOPs, databases, and real-world projects.

Input & Output

1. Variables

A variable is a name used to store a value in a Python program. Python automatically determines the type of value stored in the variable.

name = "Samadhan"
age = 25

print(name)
print(age)

Output:

Output

Samadhan
25

2. Data Types

Data types define the kind of value stored in a variable. Python provides several built-in data types.

Data Type	Example
int	25
float	25.50
str	"Python"
bool	True

3. Type Conversion

Type conversion means changing a value from one data type to another data type.

age = "25"

age = int(age)

print(age)
print(type(age))

Output:

Output

25
<class 'int'>

4. Operators

Operators are symbols used to perform operations on values and variables.

a = 10
b = 5

print(a + b)
print(a - b)
print(a * b)
print(a / b)

Output:

Output

5. Strings

A string is a sequence of characters. Strings are commonly used to store names, messages, addresses, and other text data.

name = "Samadhan"

print(name)
print(name.upper())

Output:

Output

Samadhan
SAMADHAN

6. Input & Output

Python provides the input() function to receive data from the user.

name = input("Enter your name: ")

print("Welcome", name)

Example Output

Enter your name: Samadhan
Welcome Samadhan

Example 🌍🫥

Suppose we want to store information about a student at CIIT Training Institute.

student_name = "Samadhan"
course = "Python Programming"
experience = 0

print("Student:", student_name)
print("Course:", course)
print("Experience:", experience)

Output:

Output

Student: Samadhan
Course: Python Programming
Experience: 0

CIIT Learning Point

Before learning advanced Python concepts, make sure you are comfortable with variables, data types, type conversion, operators, strings, and user input. These concepts will be used throughout your Python development journey.

CIIT Practice Task

Create a Python program that accepts a student's name and course and displays the information.

name = input("Enter student name: ")
course = input("Enter course name: ")

print("Student:", name)
print("Course:", course)

Output:

Output

Enter student name: Samadhan
Enter course name: Python Programming
Student: Samadhan
Course: Python Programming

Summary :

Python Basics introduces the core concepts required for programming with Python. You learned about variables, data types, type conversion, operators, strings, and input and output. These concepts form the foundation for writing practical Python programs.
