如何从txt文件创建csv文件，并在"x“字符后使用列分隔符

import csv

def create_csv_from_txt(txt_file, csv_file, delimiter, x_character):
    with open(txt_file, 'r') as txt:
        data = txt.read()
        index = data.find(x_character) + 1

    with open(csv_file, 'w', newline='') as csv_file:
        writer = csv.writer(csv_file, delimiter=delimiter)
        writer.writerow(['Column1', 'Column2'])  # 写入csv文件的表头
        writer.writerow([data[:index], data[index:]])  # 写入数据到csv文件

    print("CSV文件创建成功！")

# 示例调用
txt_file = 'input.txt'
csv_file = 'output.csv'
delimiter = ','  # 列分隔符，可以根据需求修改
x_character = 'x'  # 在"x"字符后使用列分隔符，可以根据需求修改

create_csv_from_txt(txt_file, csv_file, delimiter, x_character)
