Why does this keep on giving me a list index out of range error?
Question
count = 0
badIndices = [59,64,68,72,74,77,79,103,104,108,109,118,119,123,124,130,133,139]
test1 = []
csvCourses = []
csvExamTime = []
examTime = []
with open("final_exam_schedule.csv") as file:
reader = csv.reader(file, delimiter = ",")
next(reader)
for row in reader:
csvCourses.append(row)
for i in range(len(csvCourses)):
csvExamTime.append(csvCourses[i][5])
examTime.append(findSchedule(csvCourses[i][4],csvCourses[i][1],csvCourses[i][3],csvCourses[i][2]))
for i in badIndices:
test1.append(csvCourses[i][5])
for i in badIndices:
if count >= len(test1):
break
else:
count += 1
examTime[i] = test1[count] #this is where I get my error
every time I try to assign examTime[i] to test1, it gives me "out of range", but I thought that my if statement made sure that it didn't exceed the range?
For reference, examTime contains 155 different indices, and the badIndices list are the ones that aren't returning a value, so I'm going to that exact index and assigning it a value. findSchedule() is my function that has a bunch of ifs and elses to assign examTime, I didn't include it since it is really long and unnecessary to the problem. Only the specific bad indices don't return a value, the rest do.
edit: ok here is the findSchedule function

It's tough to say without knowing what your data looks like, but here's what I think,
Your count variable is being incremented too early. In python list indexes start at 0 and go to len(list)-1 as the last index. You're kind of starting at count=1 so it's possible that on the last iteration count=len(list) which gives the error. Try this as a correction for the latter part of your code:
for i in badIndices:
if count >= len(test1):
break
else:
examTime[i] = test1[count]
#We increment count after it is used
#to avoid an error
count+=1
