如何使用python对从txt文件中读取的两列进行排序？

with open('file.txt', 'r') as file:
    lines = file.readlines()

data = [line.strip().split() for line in lines]

sorted_data = sorted(data, key=lambda x: x[0])  # 按照第一列排序

sorted_data = sorted(data, key=lambda x: x[1])  # 按照第二列排序

with open('sorted_file.txt', 'w') as file:
    for row in sorted_data:
        file.write(' '.join(row) + '\n')

with open('file.txt', 'r') as file:
    lines = file.readlines()

data = [line.strip().split() for line in lines]

sorted_data = sorted(data, key=lambda x: x[0])  # 按照第一列排序

with open('sorted_file.txt', 'w') as file:
    for row in sorted_data:
        file.write(' '.join(row) + '\n')
