This homework is a makeup homework. 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:
temp = [ ('Aberporth', 'aberporthdata.txt'),
('Armagh', 'armaghdata.txt'),
('Ballypatrick Forest', 'ballypatrickdata.txt'),
('Bradford', 'bradforddata.txt'),
('Braemar', 'braemardata.txt'),
('Camborne', 'cambornedata.txt'),
('Cambridge NIAB', 'cambridgedata.txt'),
('Cardiff Bute Park', 'cardiffdata.txt'),
('Chivenor', 'chivenordata.txt'),
('Cwmystwyth', 'cwmystwythdata.txt'),
('Dunstaffnage', 'dunstaffnagedata.txt'),
('Durham', 'durhamdata.txt'),
('Eastbourne', 'eastbournedata.txt'),
('Eskdalemuir', 'eskdalemuirdata.txt'),
('Heathrow', 'heathrowdata.txt'),
('Hurn', 'hurndata.txt'),
('Lerwick', 'lerwickdata.txt'),
('Leuchars', 'leucharsdata.txt'),
('Lowestoft', 'lowestoftdata.txt'),

('Wick Airport', 'wickairportdata.txt'),
('Yeovilton', 'yeoviltondata.txt') ]
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:
UK City: Number of lines
1: Aberporth: 876 lines
2: Armagh: 1932 lines

30: Stornoway Airport: 1686 lines
31: Sutton Bonington: 660 lines
32: Tiree: 1032 lines
33: Valley: 997 lines
34: Waddington: 804 lines

36: Wick Airport: 1200 lines
37: Yeovilton: 592 lines
Question 1
Write a program that will read these files (you cannot modify these original files, as your program will be tested on copies of these originals) and output the city in the UK that got the most amount of rain in a given month.
Your program should output
- the city
- the year
- the month (expressed as January, February, ... December)
- 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
- the city
- the year
- the month (expressed as January, February, ... December)
- 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 the list of cities in two columns, the first column containing years, the second the city names. The city names are all aligned, one above each other:
Year City ... 1865 Armagh ... 1883 Sheffield ...
Grading
- Documentation, style, and readability: 20 points
