0x01-python-if_else_loops_functions

Python - if/else, loops, functions

In this project, I began utilizing conditionals and loops in Python by using if, if ... else, break, continue, pass, and range statements with while and for loops. I practiced writing my own Python functions while learning about scope of variables, tracebacks, and arithmetic operators.

Function Prototypes

Python Scripts

• Allowed editors: vi, vim, emacs
• All your files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5)
• All your files should end with a new line
• The first line of all your files should be exactly #!/usr/bin/python3
• A README.md file, at the root of the folder of the project, is mandatory
• Your code should use the pycodestyle (version 2.8.*)
• All your files must be executable
• The length of your files will be tested using wc

C Scripts

• Allowed editors: vi, vim, emacs
• All your files will be compiled on Ubuntu 20.04 LTS using gcc, using the options -Wall -Werror -Wextra -pedantic -std=gnu89
• All your files should end with a new line
• Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl
• You are not allowed to use global variables
• No more than 5 functions per file
• In the following examples, the main.c files are shown as examples. You can use them to test your functions, but you don’t have to push them to your repo (if you do we won’t take them into account). We will use our own main.c files at compilation. Our main.c files might be different from the one shown in the examples
• The prototypes of all your functions should be included in your header file called lists.h
• Don’t forget to push your header file
• All your header files should be include guarded

  • 0-positive_or_negative.py: Python program that assigns a random signed number to the variable number each time it is executed and prints whether number is positive or negative.
  • Prints the number followed by:
    • If the number is greater than 0: is positive
    • If the number is 0: is zero
    • If the number is less than 0: is negative
    • Followed by a new line.
  • Completion of this source code.

• 1. The last digit

  • 1-last_digit.py: Python program that assigns a random signed number to the variable number each time it is executed and prints its last digit.
