我正在从API中提取以下数据。数据以b
前缀开头,该前缀根据Python 3.3 documentation表示我们正在处理“字节文字”,其中转义序列\t
和\n
代表ASCII水平标签(TAB)和ASCII换行符(LF)。

但是,我似乎无法将这些数据保存到制表符分隔的csv文件中。我尝试了几种方法将此数据保存到csv文件中,但都失败了,包括以下内容:
with open("folder_GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2_/" + grl_id + ".csv", "w") as csv_file:
writer = csv.writer(csv_file)
for row in csv_file:
print(row)
这给了我以下错误:
for row in csv_file:
io.UnsupportedOperation: not readable
更新: 因此,事实证明问题出在其他地方。在进行各种测试时,我实际上设法生成了与您相同的文件,以为输出看起来不正确,因此无法正常工作。在excel中打开文件时,数据分为两列。
我现在发现原因是使用欧洲表示小数的方式表示一些数字,这是逗号179,99
。因此,Excel会将其解释为定界符,而如果我在记事本中打开文件,它将正确读取。
答案 0 :(得分:1)
好吧,您得到此错误是因为您希望将数据写入csv文件,但是在for循环中,您正尝试从该文件读取数据。如果我理解正确,则希望接收bytes对象,并将其很好地写到制表符分隔的csv文件中。下面的代码可以做到这一点:
