Python - import & modules

In this project, I learned about importing and using functions and creating modules in Python. I further practiced using the builtin function dir() and using command line arguments within Python programs.

Tasks 📃

  • 0. Import a simple function from a simple file

    • 0-add.py: Python program that imports the function def add(a, b): from the file add_0.py and prints the result of the addition 1 + 2 = 3.
    • Output: <a value> + <b value> = <add(a, b) value> followed by a new line.

  • 1. My first toolbox!

    • 1-calculation.py: Python program that imports functions from the file calculator_1.py and prints the result of the addition, subtraction, multiplication and division of 10 and 5.
    • Output: <a value> <operator> <b value> = <operation(a, b) value> followed by a new line.

  • 2. How to make a script dynamic!

    • 2-args.py: Python program that prints the number of and list of its arguments.
    • Output: [Number of arguments] argument (if number is one) or arguments (otherwise), followed by:
      • : (or . if no argumets were passed), followed by
      • A new line, followed by
      • One argument per line - the position of the argument (starting at 1) followed by : followed by the argument value and another new line.

  • 3. Infinite addition

    • 3-infinite_add.py: Python program that prints the result of the addition of all arguments.
    • Output: Sum of the arguments followed by a new line.

  • 4. Who are you?

    • 4-hidden_discovery.py: Python program that prints all the names defined by the compiled module hidden_4.pyc.
    • Output: One name per line in alphabetical order.
    • Names starting with __ are not printed.

  • 5. Everything can be imported

  • 6. Build my own calculator!

    • 100-my_calculator.py: Python program that imports all functions from the file calculator_1.py and handles basic operations.
    • Usage: ./100-my_calculator.py <a> <operator> <b> followed by a new line.
    • Output: <a> <operator> <b> = <result> followed by a new line.
    • The parameter operator can be:
      • + for addition
      • - for subtraction
      • * for multiplication
      • / for division
    • If the operator is none of the above, the function prints Unknown operator. Available operators: +, -, *, and / followed by a new line and exits with a status value of 1.
    • If the number of arguments is not three, the program prints Usage: ./100-my_calculator.py <a> <operator> <b> followed by a new line and exits with a status value of 1.

  • 7. Easy print

    • 101-easy_print.py: Python program that prints #pythoniscool followed by a new line in the standard output.
    • Without using print, eval, open, or sys.

  • 8. ByteCode -> Python #3

  • 9. Fast alphabet

    • 103-fast_alphabet.py: Python program that prints the alphabet in uppercase, followed by a new line.
    • Without using loops, conditoinals, str.join(), string literals, or system calls.
