python-course

Description

This repo contains solutions for the Python Elem. Tasks.
Each package inside the tasks folder represents each task of the course.

The project was created using the Visual Studio Code (version 1.60.0) and Python 3.9.1.

Installation

You can directly clone this project and try it for yourself:

git clone https://github.com/gotoindex/python-course.git

Usage

This project takes advantage of Python's argparse. To launch a task, call it in console using python or python3 command:

python3 path/to/file <arguments>

Example:

python3 tasks/task1/method1.py 8 8

Goals

During the development of the project following goals were achieved:

• Learned how to use following modules:
  • argparse
  • unittest
• Completed following tasks:
  • Task 1, "Chessboard"
  • Task 2, "Envelope Analysis"
  • Task 3, "Sorting Triangles"
  • Task 4, "File Parser"
  • Task 5, "Number to a Word"
  • Task 6, "Lucky Tickets"
  • Task 7, "Number Sequence"
  • Task 8, "Fibonacci Series for a Range"
• Created tests for all completed tasks.

Additional software and services used during the development:

• Git
• Visual Studio Code

Task description

Here is a full description of all tasks:

Note that this text was roughly translated to english and thus may contain simple mistakes.

1. Chessboard
   Display a chessboard with the specified dimensions of height and width, according to the principle:
   * * * * * *
    * * * * * *
   * * * * * *
    * * * * * *
   The program is launched by calling the main class with parameters.

2. Envelope Analysis
   There are two envelopes with sides (a, b) and (c, d) determine if one envelope can be inserted into another. The program must handle floating point input. The program asks custom envelope sizes one setting at a time. After each calculation, the program asks the user if he wants to continue. If the user answers “y” or “yes” (without register), the program continues to work from the beginning, otherwise it ends execution.

3. Sorting Triangles
   Develop a console program that prints triangles in descending order their area. After adding each new triangle, the program asks if it wants user add another one. If the user answers “y” or “yes” (case insensitive), the program will ask you to enter data for one more triangle, otherwise it outputs the result to the console.

• The area of the triangle should be calculated using Heron's formula.
• Each triangle is identified by the name and the lengths of its sides. Input format (comma delimited):
  <name>, <side length>, <side length>, <side length>
• The application must handle floating point input.
• Input must be case insensitive, spaces, tabs.
• Data output should be the following example:
  ============= Triangles list: ===============
  1. [Triangle first]: 17.23 сm
  2. [Triangle 22]: 13 cm
  3. [Triangle 1]: 1.5 cm

4. File Parser
   You need to write a program that will have two modes:

   1. Count the number of occurrences of a line in a text file.
   2. Replace the line with another in the specified file
      The program should accept arguments as input at startup:
   3. <path to file> <string for counting>
   4. <path to file> <string for searching> <string for replaceing>

5. Number to a Word
   You need to convert an integer to a word: 12 - twelve. Program is launched by calling the main class with parameters.

6. Lucky Tickets
   There are 2 ways to count lucky tickets:

   1. Moscow - if a six-digit number is printed on the bus ticket, and the sum of the first of three digits is equal to the sum of the last three, then this ticket is considered lucky.
   2. Leningrad, or St. Petersburg - if the sum of the even digits of the ticket is equal to the sum of the odd numbers on the ticket, then the ticket is considered lucky. Task: The ticket number is a six-digit number. One needs to write a console application that can count the number of lucky tickets. To select the calculation algorithm, a text file is read. The path to the text file is set in the console after starting the program. Algorithm indicators: 1 - the word 'Moskow' 2 - the word 'Piter' After setting all the necessary parameters, the program should display the number of lucky tickets for the specified counting method.

7. Number Sequence
   The program displays a series of natural numbers separated by commas, the square of which is less than a given n. The program is launched by calling the main class with parameters.

8. Fibonacci Series for a Range
   The program allows you to display all Fibonacci numbers that are in the specified range. The range is given by two arguments when calling the main class. Numbers are displayed separated by commas Ascending.
