我想使用我的csv文件的某一列中的数据在python的csv文件中生成另一列

你当然可以做到

output = []

# read and process the csv file
with open("data.csv", "r") as f:
    reader = csv.reader(f)
    for args in reader:
        if args[0] == "Name":
            output.append([ "Name", "Important", "x"])
            continue

        if args[1] == "Yes":
            output.append([args[0], args[1], "important"])
        else:
            output.append([args[0], args[1], "not important"])

# write the processed data back to csv file
with open("data.csv", "w") as f:
    writer = csv.writer(f)
    writer.writerows(output)

希望这可以帮助！
