MAKE-UP ASSIGNMENT

This homework is a make-up assignment. You have until Friday evening, May 2nd, midnight to submit it. You can work in pair-programming on this assignment.

Logistics for Grading

The algorithm used to incorporate this assignment in your overall final grade is the following:

  # hw13 is the makeup assignment.
  
  if  youDoThisMakeupAssignment():
      hw13 = # your grade on this assignment
  else:
      hw13 = 0

  # create a list of all your homework assignment grades.  homework assignments missed get a 0
  homeworkGrades = [ hw1, hw2, hw3, hw4, hw5, hw6, hw7, hw8, hw9, hw10, hw11, hw12 ]

  # find the lowest grade
  minHW = min( homeworkGrades )

  # find where the lowest grade is
  minIndex = homeworkGrades.index( minHW )

  # replace lowest with grade of hw13 if this one is greater
  if hw13 > minHW:
      L[ minIndex ] = hw13

  # Drop the lowest assignment of the semester
  minHW = min( homeworkGrades )
  minIndex = homeworkGrades.index( minHW )
  homeworkGrades.pop( minIndex )

Your Assignment

• Download this file: AllUKTemperatures.zip
• Save the file in a folder of your choosing
• Unzip the zip file. You should get 37 text files. You should recognize two of them as files you have played with before.
• Store this simple (undocumented) Python program in the same directory:

def getStats():
    print( "    %20s: Number of lines" % "UK City" )
    for i,pair in enumerate( temp ):
        name = pair[0]
        fileName = pair[1]
        file = open( fileName, 'r' )
        print( "%2d: %20s:  %5d lines" %
               ( i+1, name, len( file.readlines() ) ) )
        file.close()

def main():
    getStats()

main()

• Run the program. You should get an output of this form:

This program is just for you to have a seed of code to get started. You do not need to use the function getStats() in your own program.

Question 1

Write a program called hw13a.py that will read these files (you can modify these original files for debugging, but your submitted program will be tested on copies of my originals) and output the city in the UK that got the most amount of rain in a given month. Your program will ask the user for the year first, and then for the month. Here is an example

please enter year: 2010
please enter month: 12

Your program should output

1. A title clearly indicating Question 1 in it.
2. the city
3. the year
4. the month (expressed as January, February, ... December)
5. the amount of rain recorded

Question 2

Make your program also output the city that experienced the biggest difference in tmax-tmin temperature since 2000, included.
Your program should output

1. A title clearly indicating Question 2 in it.
2. the city
3. the year
4. the month (expressed as January, February, ... December)
5. the largest difference observed

Question 3

Make your program output all the city names sorted by year when a temperature recording was first made for them. For example, the first temperature recording for Armagh was in 1865. The first temperature recording for Sheffield was in 1883. Therefore Armagh should be listed before Sheffield in your output.
Your program should output a title clearly indicating Question 3 in it, followed by the list of cities in two columns, the first column containing the years, the second the city names. The city names are all aligned, one above each other:

Question 3
==========
Year  City
...
1865  Armagh
...
1883  Sheffield
...
