csv.Error: iterator should return strings, not bytes

python 读取csv文件问题

with open("fer2013.csv", "rb", encoding="utf-8") as vsvfile:   reader = csv.reader(vsvfile)   rows = [row for row in reader]   print(rows)

输出：

Error: iterator should return strings, not bytes (did you open the file in text mode?)

问题分析

因为此csv文件并非二进制文件， 只是一个文本文件。

问题解决

with open("fer2013.csv", "rt", encoding="utf-8") as vsvfile:   reader = csv.reader(vsvfile)   rows = [row for row in reader]   print(rows)

或者

# 因为open()默认打开文本文件with open("fer2013.csv", "r", encoding="utf-8") as vsvfile:   reader = csv.reader(vsvfile)   rows = [row for row in reader]   print(rows)
