在Python中按字母顺序排列CSV文件中的行

import csv

rows = []
with open('file.csv', 'r') as file:
    csv_reader = csv.reader(file)
    for row in csv_reader:
        rows.append(row)

sorted_rows = sorted(rows, key=lambda x: x[column_index])

with open('sorted_file.csv', 'w', newline='') as file:
    csv_writer = csv.writer(file)
    csv_writer.writerows(sorted_rows)

import csv

def sort_csv_by_column(csv_file, column_index):
    rows = []
    with open(csv_file, 'r') as file:
        csv_reader = csv.reader(file)
        for row in csv_reader:
            rows.append(row)
    
    sorted_rows = sorted(rows, key=lambda x: x[column_index])
    
    with open('sorted_file.csv', 'w', newline='') as file:
        csv_writer = csv.writer(file)
        csv_writer.writerows(sorted_rows)

# 调用函数进行排序
sort_csv_by_column('file.csv', 0)
