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.

• 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

  • 5-variable_load.py: Python program that imports the variable a from the file variable_load_5.py and prints its value.

• 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

  • 102-magic_calculation.py: Python function matching exactly a bytecode provided by Holberton School.

• 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.
