我希望使用python从这个csv文件中删除“month”列，我得到一个错误，上面写着“keyerror:month”

既然这只是你不想做的第一件事，你可以：

旧表

fieldnames = ["month", "harry styles: (Worldwide)", "zayn malik: (Worldwide)", "niall Horan: (Worldwide)", "liam payne: (Worldwide)", "louis tomlinson: (Worldwide)", "one direction: (Worldwide)"]


fieldnames

['month',
 'harry styles: (Worldwide)',
 'zayn malik: (Worldwide)',
 'niall Horan: (Worldwide)',
 'liam payne: (Worldwide)',
 'louis tomlinson: (Worldwide)',
 'one direction: (Worldwide)']

fieldnames.pop(0)

fieldnames

['harry styles: (Worldwide)',
 'zayn malik: (Worldwide)',
 'niall Horan: (Worldwide)',
 'liam payne: (Worldwide)',
 'louis tomlinson: (Worldwide)',
 'one direction: (Worldwide)']

新表格

fieldnames = ["month", "harry styles: (Worldwide)", "zayn malik: (Worldwide)", "niall Horan: (Worldwide)", "liam payne: (Worldwide)", "louis tomlinson: (Worldwide)", "one direction: (Worldwide)"]


fieldnames

['month',
 'harry styles: (Worldwide)',
 'zayn malik: (Worldwide)',
 'niall Horan: (Worldwide)',
 'liam payne: (Worldwide)',
 'louis tomlinson: (Worldwide)',
 'one direction: (Worldwide)']

fieldnames.pop(0)

fieldnames

['harry styles: (Worldwide)',
 'zayn malik: (Worldwide)',
 'niall Horan: (Worldwide)',
 'liam payne: (Worldwide)',
 'louis tomlinson: (Worldwide)',
 'one direction: (Worldwide)']

正确位置的

print（list（line.keys（））

将显示DictReader使用过的键。您能否显示

onedirectionsearch.csv
