如何在python中加速将大字符串写入文件

with open('output.txt', 'w') as file:
    for line in large_string.splitlines():
        file.write(line + '\n')

with open('output.txt', 'w') as file:
    file.writelines(large_string)

import numpy as np

# 将字符串转换为numpy数组
array = np.array(list(large_string))

# 将数组写入文件
array.tofile('output.txt', sep='', format='%s')

import threading

def write_to_file(file, string):
    with open(file, 'w') as f:
        f.write(string)

# 创建多个线程并行写入文件
threads = []
for i in range(10):
    t = threading.Thread(target=write_to_file, args=('output.txt', large_string))
    threads.append(t)
    t.start()

# 等待所有线程完成
for t in threads:
    t.join()
