使用Python对.csv文件进行重新排序

import csv
import operator

with open('input.csv', 'r') as file:
    reader = csv.reader(file)
    data = list(reader)

sorted_data = sorted(data, key=operator.itemgetter(0))

sorted_data = sorted(data, key=operator.itemgetter(0), reverse=True)

sorted_data = sorted(data, key=operator.itemgetter(0, 1))

sorted_data = sorted(data, key=lambda x: int(x[0]))

with open('output.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(sorted_data)
