Introduction to Python

[Jessica Brown]

Python is a versatile, high-level programming language known for its readability and broad applicability. With an extensive library ecosystem, Python is used for everything from web development to machine learning and scientific computing. Its beginner-friendly syntax and powerful features make it one of the most popular programming languages today.

What is Python Best Used For?

• Web development using frameworks like Django or Flask.
• Data analysis, visualization, and machine learning.
• Writing scripts for automation and system administration.
• Building APIs, games, and desktop applications.
• Scientific computing and academic research.

Example Python Script

This example demonstrates variables, a loop, and output.

# Declare variables
greeting = "Hello, Python Programmer!"
count = 5

# Display greeting
print(greeting)

# Loop through numbers 1 to count
for i in range(1, count + 1):
    print(f"Iteration: {i}")

# Print completion message
print(f"Loop completed! Total iterations: {count}")

Explanation:

1. Variables: greeting is a string holding the welcome message, and count is an integer specifying the loop range.
2. Loop: The for loop iterates through the range 1 to count. String interpolation with f-strings formats dynamic output.
3. Output: The script outputs the greeting, each iteration, and a completion message.

Sample Output:

Hello, Python Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
