Python csv 阅读器：遍历 csv 文件

发布于03月21日

我有几个CSV文件，它们被命名为:list_csv_X，X从0到5.我想做一个循环来用Python读取它们.

我目前正在手动执行此操作:

for filepath in list_csv_0:
    with open(filepath,'r',encoding="utf8", errors='ignore') as csvfile:
        BLABLABLA
for filepath in list_csv_1:
    with open(filepath,'r',encoding="utf8", errors='ignore') as csvfile:
        BLABLABLA
for filepath in list_csv_2:
    with open(filepath,'r',encoding="utf8", errors='ignore') as csvfile:
        BLABLABLA

我该怎么做呢？

非常感谢!

推荐答案

If I understand correctly, each of your 6 items is a list of filenames, yes?

我假设这一点，因为你正在做这个，并说它目前是有效的:

for filepath in list_csv_0:

如果list_csv_0是文件名，这将导致错误，因为filepath值将是文件名的单个字符，而不是整个文件名.

您可以遍历这些列表


list_csvs = [list_csv_0,list_csv_1,list_csv_2,list_csv_3,list_csv_4,list_csv_5]

for list_csv in list_csvs:
    for filepath in list_csv:
        with open(filepath,'r',encoding="utf8", errors='ignore') as csvfile:
            BLABLABLA
