在Python中优雅地处理文件和路径

在Python中，处理文件和路径通常会用到一些内置的模块，如os, path, 和shutil等。以下是一些常用的处理方法：

检查路径是否存在：

import os
file_path = '/path/to/file'
if os.path.exists(file_path):
    print(f"Path exists: {file_path}")
else:
    print(f"Path does not exist: {file_path}")

获取文件或目录的完整路径：

import os
file_path = '/path/to/file'
absolute_file_path = os.path.abspath(file_path)
print(f"Absolute File Path: {absolute_file_path}")

创建新文件或重命名文件：

import os
# 创建新文件
new_file_path = '/new/path/to/file.txt'
os.makedirs(os.path.dirname(new_file_path)), exist_ok=True)
with open(new_file_path, 'w')) as file:
    file.write('Hello, World!')
# 重命名文件
old_file_path = '/path/to/old/file.txt'
new_file_name = 'new_file.txt'
new_file_path = os.path.join(os.path.dirname(old_file_path))), new_file_name)
if os.path.exists(new_file_path)):
    os.replace(old_file_path, new_file_path))
    print(f"File {old_file_path}} successfully renamed to {new_file_path}")
else:
    print("Renaming failed. File not found.")
