10 Beginner Python Projects to Boost Your Coding Confidence

Today I share ten beginner-level Python examples. These cases are not difficult, but they cover a wide range of concepts, making them ideal for beginners to build confidence and improve proficiency.

Case 1: Permutations and Combinations

Requirement: List all distinct permutations of four digits without repetition.

Analysis: Simple enumeration of permutations.

Code:

Case 2: Tiered Commission Calculation

Requirement: Given a sales amount, compute the commission based on a tiered scheme (≤100k:10%, ≤200k:7.5% on excess, ≤400k:5% on excess, ≤600k:3% on excess, ≤1M:1.5% on excess, >1M:1% on excess).

Analysis: Use a number line to determine the applicable tier; note that higher sales receive lower marginal rates.

Code:

Case 3: Find Integer Value

Requirement: Find an integer i such that i+100 is a perfect square and i+268 is also a perfect square.

Analysis: Test numbers up to 100,000, checking the square root conditions.

Code:

Case 4: Day of Year Calculator

Requirement: Input year, month, day and determine which day of the year it is.

Analysis: Sum days of preceding months and add current day, accounting for leap years.

Code:

Case 5: Integer Sorting

Requirement: Input three integers xyz and output them in ascending order.

Analysis: Simple comparisons or use Python list sort.

Code:

Case 6: Print Character Art (Letter P)

Requirement: Use “*” to output a simple ASCII letter P.

Analysis: Straightforward pattern printing.

Code:

Case 7: chr Function Demo

Requirement: No specific requirement; demonstrates chr usage.

Analysis: Author showcases capabilities.

Code:

Case 8: Multiplication Table

Requirement: Print the 9×9 multiplication table.

Analysis: Basic introductory example.

Code:

Case 9: Chessboard Output

Requirement: Print an 8×8 chessboard pattern of black and white squares.

Analysis: Use i for rows and j for columns; color determined by (i+j) parity.

Code:

Case 10: Print Staircase

Requirement: Print a staircase shape.

Analysis: Use i for rows and j for columns; j depends on i to output the appropriate number of blocks.

Code:
