python如果不是整数_Python：列表索引必须是整数，而不是str？

所以我有如下代码：with open(completeCSV, 'r') as csvfile:

test = csv.reader(csvfile, delimiter=';')

for line in test:

print(line)

i = i + 1 # on the first line, i will equal 1

count = line[0]

if count == '1':

for prof in proflist: # vertex1=prof

if line[1].lower() == proflist[prof]:

# if vertex1 is a professor, you want to keep the edge.

lines_to_keep.append(i)

break # breaks and doesn't check the rest of profs

它基本上读取一个CSV，并检查CSV中的一个值是否等于列表proflist中的另一个值。在

我得到了这个错误：Traceback (most recent call last):

File "C:/Users/sskadamb/PycharmProjects/BetterDelimiter/filter.py", line 50, in

if line[1].lower()==proflist[prof]:

TypeError: list indices must be integers, not str

是因为proflist[prof]？但是我想检查

proflist反对{}。我该怎么做？我做错了什么？我能不能不迭代一下这样的列表？在
