如何在 Python 中创建文件夹和保存文件

创建文件夹

要使用 Python 创建文件夹,可以使用 os 模块中 makedirs() 函数:

import os

# 创建名为 "new_folder" 的文件夹
os.makedirs("new_folder")

makedirs() 函数可以递归创建不存在的父目录。

保存文件

要使用 Python 保存文件,可以使用 open() 函数:

import os

# 打开一个名为 "test.txt" 的文件,并以写入模式 "w" 打开
with open("test.txt", "w") as f:
    # 将内容写入文件
    f.write("你好,世界!")

with 语句确保文件在完成写入操作后被正确关闭。

示例

将以下代码保存为 create_folder_and_save_file.py

import os

# 创建名为 "new_folder" 的文件夹
os.makedirs("new_folder")

# 在 "new_folder" 中打开一个名为 "test.txt" 的文件,并以写入模式 "w" 打开
with open(os.path.join("new_folder", "test.txt"), "w") as f:
    # 将内容写入文件
    f.write("你好,世界!")

运行该代码将创建一个名为 "new_folder" 的文件夹,并在其中保存一个名为 "test.txt" 的文件,内容为 "你好,世界!"。

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
