1. For this lab, you have to solve four required problems. Some problem requires from you to input some data and do some calculation.
2. There is a bonus problem (the last one). It is optional
3. Each problem should be solved inside its own main function with comments in between.
4. Think about the possible data types for each data in every problem.
5. Choose names for your variables that make sense, don't use any  variable name that is one character only. Use good, multi-character,  meaningful identifiers (variables) names. There is a 5% penalty for not  doing that.
6. Document your work by putting comments at the top of your program.  The possible comments that you need for this program are the program  prolog (name of the programmer, your class and section, the date when  you finished working on the program and the purpose of the program).   There is a 5% penalty for not doing that.
7. In addition to that, you have to write some comments between the  lines of the code to show why you write your code this way. Remember  that comments in Python are either:
   • Starts with // in case the comment is one line only.
   • Or it is between /*  */ if the comment is taking more than one line.
