不要尝试重新发明轮子。
如果要读取CSV文件中的行，请使用标准库中的Pythoncsv模块。
> cat test.py
import csv
with open('some.csv') as f:
reader = csv.reader(f)
for row in reader:
print(row)
> cat some.csv
"114111","Planes,Trains,and Automobiles","50","BOOK"
> python test.py
['114111', 'Planes,Trains,and Automobiles', '50', 'BOOK']
[]
任务完成！
