Week 1 — Python Module Assignment (Professor: Anudit Pokhrel)

This repository contains six small, focused Python programs completed for the Week 1 assignment. Each script introduces a fundamental concept: type conversion and formatting, string parsing, indexing and slicing, conditional logic, frequency counting, and character classification.

Project Overview

• Purpose: Practice core Python concepts via small, interactive scripts.
• Scope: Six standalone programs, each prompting for input and printing results.
• Platform: macOS or any system with a modern Python interpreter.

Folder Structure

• assignment_week_1_q1.py — Convert a decimal number to int and string; format output.
• assignment_week_1_q2.py — Extract uppercase initials from a provided full name.
• assignment_week_1_q3.py — Slice a given word from a specified starting index.
• assignment_week_1_q4.py — Assess password strength using simple rules.
• assignment_week_1_q5.py — Count frequency of alphabetic characters in a string.
• assignment_week_1_q6.py — Count vowels and consonants in a string.

Prerequisites

• Python 3.8+ recommended (any modern 3.x works)
• Terminal access to run scripts (python3 on macOS)

How to Run

1. Open Terminal and navigate to the project folder:

   cd "/Users/prashantkoirala/Desktop/Python Module Assignemnt"

2. Run a script with:

   python3 assignment_week_1_qX.py

   Replace X with 1–6 depending on the question.

Script Details and Examples

Q1 — Number Conversion and Formatting (assignment_week_1_q1.py)

• Prompts for a decimal number, converts it to int and str, and prints the original float with two decimal places.
• Concepts: type casting (int, str), string formatting (format/{:.2f}).
• Example:

  Please, enter a decimal number: 12.345
  Original float: 12.35
  Converted to integer: 12
  Converted to string: "12.345"
  

Q2 — Initials from Full Name (assignment_week_1_q2.py)

• Trims whitespace, splits the full name by spaces, and prints uppercase initials from the first and last parts.
• Concepts: strip, split, indexing, string methods.
• Notes: For a single-name input, both initials derive from the same word (A.A).
• Example:

  Please, enter your full name: Ada Lovelace
  Your initials are: A.L
  

Q3 — Substring from Index (assignment_week_1_q3.py)

• Prompts for a word and a starting index, then prints the substring from that index to the end.
• Concepts: input parsing, int conversion, slicing (word[index:]).
• Edge behavior: Negative indices are allowed (Pythonic slicing). Out-of-range indices yield an empty string without error.
• Example:

  Please, enter a word: python
  Enter starting index:
  2
  Substring from index 2 : "thon"
  

Q4 — Password Strength (assignment_week_1_q4.py)

• Evaluates password strength using simple heuristics:
  • Weak: length < 6 or only letters (isalpha).
  • Moderate: length >= 6 and alphanumeric (isalnum).
  • Strong: length >= 8 and contains at least one of @#$%&.
  • Else: Moderate.
• Concepts: conditionals (if/elif/else), length checks, membership tests.
• Notes: The strong rule is limited to the special set @#$%&. Other symbols are treated as non-strong unless included in that set.
• Example:

  Please, enter your password: Passw0rd@
  Password strength: Strong
  

Q5 — Alphabet Frequency (assignment_week_1_q5.py)

• Lowercases the text and counts occurrences of alphabetic characters (a–z). Non-letters are ignored.
• Concepts: dictionaries, iteration, isalpha, case normalization.
• Output order follows first occurrence insertion order of characters.
• Example:

  Please, enter a string: Hello, World!
  h → 1
  e → 1
  l → 3
  o → 2
  w → 1
  r → 1
  d → 1
  

Q6 — Vowel vs Consonant Count (assignment_week_1_q6.py)

• Lowercases input and counts vowels (aeiou) vs consonants; non-alphabetic characters are ignored.
• Concepts: classification, membership tests, conditional increments.
• Example:

  Please, enter a string:
  Hello, World!
  Vowels: 3
  Consonants: 7
  

Testing Tips

• Provide valid inputs to avoid ValueError (e.g., enter an integer for index in Q3).
• Try edge cases:
  • Q2: Single-word name, multiple middle names.
  • Q3: Negative and very large indices.
  • Q4: Short passwords, all letters, all digits, and with symbols outside @#$%&.
  • Q5: Mixed punctuation and spaces.
  • Q6: Strings with no letters.
