What Are Variables and How Are They Used in Python?

In Python, variables are used to store and manage data. They are dynamically typed, meaning you don’t need to declare the data type explicitly. Here’s a brief overview:

# Example of declaring and using variables
name = "John"
age = 25
height = 1.75

Variable Types:

  • String: Holds textual data.
  • Integer: Stores whole numbers.
  • Float: Represents numbers with decimal points.

Understanding Python Data Structures: Lists and Dictionaries

Data structures are crucial for organizing and manipulating data efficiently. Two fundamental structures in Python are lists and dictionaries.

Lists:

  • Ordered collection of items.
  • Access elements using indices.
  • Example: fruits = ['apple', 'banana', 'orange']

Dictionaries:

  • Key-value pairs for efficient data retrieval.
  • Example: person = {'name': 'John', 'age': 25, 'city': 'New York'}

Control Flow: How to Use If Statements and Loops

Controlling the flow of a program is vital. Python offers if statements and loops for decision-making and iteration.

If Statements:

# Example of an if statement
age = 18
if age >= 18:
    print("You are an adult.")
else:
    print("You are a minor.")

Loops:

# Example of a for loop
for i in range(5):
    print(i)

Functions: Building Blocks of Python Programs

Functions are reusable blocks of code that perform a specific task. They enhance code modularity and readability.

# Example of a function
def greet(name):
    print(f"Hello, {name}!")

# Calling the function
greet("Alice")

Function Components:

  • Name: Identifies the function.
  • Parameters: Input values specified when defining the function.
  • Return Value: The output of the function.

Handling Errors: Try and Except Blocks

Dealing with errors is an essential skill for any programmer. Python provides the try and except blocks to handle exceptions gracefully.

# Example of try and except blocks
try:
    result = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero.")
