Problem #1
- Write a program called hw9a.py that outputs average length of the presidency of US presidents, categorized by party. Your program should get the information from a file called presidents.txt, whose contents is available here.
- If you are working on beowulf, you can get a copy of the file into your account this way:
getcopy presidents.txt
- The output of your program should be only a few lines long. We do not want to see the list of presidents. Just something like this:
Average length of presidency. File presidents.txt contains 44 presidents. Democratic presidents: x.xx years Republican presidents: x.xx years Others: x.xx years
- The number of presidents (44) should be the number found by your program in the text file. When I test your program, I may provide a presidents.txt file with fewer than 44 presidents. Or a file that has just a header and no presidents at all! Or even a file with nothing in it, just empty. Be sure you test your program well so that it doesn't crash on any of these potential input files.
- Submit your program as follows:
rsubmit hw7 hw7a.py
