Some Common Terms In Python Programming And Their Explanations_Part One

 

1. Variable

• Explanation: A variable is a name that refers to a value stored in memory. In Python, variables are dynamically typed, meaning you don't need to declare the type of a variable before assigning a value to it.

Example:

x = 10  # Here, x is a variable storing the value 10.

2. Data Types

• Explanation: Data types define the type of value a variable can hold. Common data types in Python include integers ('int'), floating-point numbers ('float'), strings ('str'), and booleans (bool).

Example:

age = 25             # int
height = 5.9         # float
name = "Alice"       # str
is_student = True    # bool

3. List

• Explanation: A list is a collection of items that are ordered and changeable. Lists are one of the most versatile data structures in Python.

Example:

fruits = ["apple", "banana", "cherry"]  # A list of fruits.

4. Tuple

• Explanation: A tuple is similar to a list, but it is immutable, meaning that once it is created, its elements cannot be changed.

Example:

coordinates = (10, 20)  # A tuple representing coordinates.

5. Dictionary

• Explanation: A dictionary is a collection of key-value pairs. Each key is unique, and it is used to access the corresponding value.

Example:
