问题描述
我不明白为什么这会给我一个“IndexError: list index out of range”。 我正在从一个简单的 csv.file 中读取数据，并尝试将值以逗号分隔。
with open('project_twitter_data.csv','r') as twf:
tw = twf.readlines()[1:] # I dont need the very first line
for i in tw:
linelst = i.strip().split(",")
RT = linelst[1]
RP = linelst[2]
rows = "{},{}".format(RT,RP)
我的输出看起来像这样
print(tw) # the original strings.

print (i)

6 linelst = i.strip().split(",")
7 # print(linelst)
----> 8 RT = linelst[1]
9 RP = linelst[2]
IndexError: list index out of range
我做错了什么？
我还注意到，在我使用了 strip().split(",") 之后，我的列表的最后出现了一个空列表，[' ']。 我可以用 twf.readlines()[1:][:-1] 删除它但错误仍然存在.. 感谢您的任何建议。
