To whom it may concern. This code is from Dr. John Keyser.
gooddata = []
for singleday in datalist:
if (singleday[0] == day) and (singleday[1] == month):
gooddata.append({singleday[2], singleday[3], singleday[4],
singleday[5]})
# Perform analysis
minsofar = 120
maxsofar = -100
numgooddates = 1
sumofmin = 0
sumofmax = 0
# so singleday in datalist is a list while singleday in gooddata is a
set?????????
for singleday in gooddata:
sumofmin += singleday[1]
sumofmax += singleday[2]
if singleday[1] < minsofar:
minsofar = singleday[1]
if singleday[2] > maxsofar:
maxsofar = singleday[2]
Could this be a bug in my Pycharm 3 compiler I have had mixed experiences
running the code.
An insertion of a space after for singleday in gooddata: line 54 caused the
program to run as desired, once, since other runs cause the error
Traceback (most recent call last):
File "C:/Users/Dad/PycharmProjects/TopDownDesign/WeatherDataSpecialDay.py",
line 56, in <module>
sumofmin += singleday[1]
TypeError: 'set' object does not support indexing
persist.
I will attach the code and test file. Please allow me to thank you in advance
for answering this query. I am new with Python and would appreciate any advice.
God Bless:
