Answer 1

您可以检查.csv 中的列是否在.xlsx 中表示，并写入新的 excel 或覆盖当前列（如果是这种情况）。

df_xlsx = pd.read_excel('excelfile.xlsx')
df_csv = pd.read_csv('csvfile.csv')

if all(elem in df_csv.columns.tolist() for elem in df_xlsx.columns.tolist()):
    df_csv[df_xlsx.columns.tolist()].to_excel('new_excelfile.xlsx')
else:
    print('cols not in csv:' ,list(set(df_xlsx.columns.tolist())-set(df_csv.columns.tolist())))
