Python Syntax

Python Variables

Variables are used to store data values. In Python, you do not need to declare the type of variable; the interpreter automatically identifies the type based on the value assigned.

Syntax:

variable_name = value

variable_name = value

Examples:

name = "Tala"         #String
age = 22              #Integer
height = 5.5          #Float
is_student = True     #Boolean

name = "Tala"         #String

age = 22              #Integer

height = 5.5          #Float

is_student = True     #Boolean

Python Data Types

Python has several built-in data types. Here are some of the most commonly used ones:

1. Numeric Types:
   • int: Integer numbers:
     age = 22
   • float: Floating-point numbers:
     height = 5.5
2. String:
   • A sequence of characters enclosed in single, double, or triple quotes:
     name = “Tala”
3. Boolean:
   • Represents True or False values:
     is_student = True

Python `input`

The input function allows the user to provide input from the keyboard. The input is always treated as a string.

Syntax:

variable_name = input("Prompt message")

variable_name = input("Prompt message")

Example:

name = input("Enter your name: ")
print("Hello, " + name + "!")

name = input("Enter your name: ")

print("Hello, " + name + "!")

Or

name = input("Enter your name: ")
print(f"Hello, {name}!")

name = input("Enter your name: ")

print(f"Hello, {name}!")
