D335 Python Practice Bank

A small collection of self-contained Python practice problems inspired by the kinds of tasks you’ll see in an intro programming / CS fundamentals course.

Code of Conduct

By using or contributing to this repository, you agree to the Code of Conduct.
In short: this repo is for practice-only content, not for sharing exam answers or graded assignment solutions.

Each file is designed so that students can:

• Read a clear problem statement at the top.
• Work in a “student solution” area.
• Compare against a reference solution (usually wrapped in a function) when they’re ready.

The focus is on:

• Basic I/O
• File handling
• Lists and indexing
• Type inspection and conditionals
• Simple numeric processing and formatting

Suggested repo name (what this README assumes):

d335-python-practice-bank

You can, of course, rename it to whatever fits your environment.

Contents

Current files expected in this repo:

• d335_month_selector_practice.py
  Practice using lists, input, loops, and basic error handling. Students choose a month index and the program prints the corresponding month name, optionally with validation.

• d335_student_info_practice.py
  Reads simple student information from a text file (first name, last name, major) and appends a formatted summary line such as:
  Student: John Smith - Major: Computer Science

• d335_totals_sum_practice.py
  Reads numeric values (e.g., expenses) from a text file, converts lines to float, computes the total, and appends a line like:
  Total: 39.00
  Good for practicing file reading, list comprehensions, numeric conversion, and :.2f formatting.

• d335_animals_summary_practice.py
  Works with a small text file containing animal names and appends a sentence summarizing them on a single line. Reinforces readlines(), .strip(), and " ".join(...).

• d335_courses_offered_practice.py
  Similar to the animals exercise, but with course names. Builds a line such as:
  Courses offered: Math, Science, History

• d335_file_stats_practice.py
  Reads several numeric scores from a file, computes min, max, and average, and appends a stats line like:
  Stats: min=76, max=95, avg=87.20
  Reinforces numeric processing, min(), max(), sum()/len(), and formatted output.

• d335_type_classifier_practice.py
  Uses a mixed list of values and an index from the user to:

  • Retrieve an element
  • Inspect its type using type(...).__name__
  • Classify the element as iterable, numeric, or “other” Great for practicing isinstance, type inspection, and conditional logic.

• data_mixture.py
  A small helper/module that may contain the shared data_mixture list for type-classification exercises (or similar shared data for other problems).
