Python os.path.join()函数详解：路径拼接的用法与示例

import os
path = os.path.join(path1, path2, ..., pathN) http:/cctv5.ccmykj.cn
http:/tv3.ccmykj.cn

import os

# 基本路径拼接
path1 = os.path.join('dir', 'subdir', 'file.txt')
print(path1)  # 输出: dir/subdir/file.txt (Linux/macOS) 或 dir\subdir\file.txt (Windows)

# 包含绝对路径
path2 = os.path.join('/home/user', 'docs', '/absolute', 'file.txt')
print(path2)  # 输出: /absolute/file.txt
http:/tv2.ccmykj.cn
http:/tv1.ccmykj.cn

# 包含空字符串
path3 = os.path.join('dir', '', 'file.txt')
print(path3)  # 输出: dir/file.txt

# 使用点号表示当前目录
path4 = os.path.join('.', 'config', 'settings.ini')
print(path4)  # 输出: ./config/settings.ini
http:/ccmykj.cn

# Windows路径
path5 = os.path.join('C:\\', 'Users', 'Public', 'Documents')
print(path5)  # 输出: C:\Users\Public\Documents

# 处理驱动器号
path6 = os.path.join('C:', 'Windows', 'System32')
print(path6)  # 输出: C:Windows\System32 (注意相对路径行为)

import os

def find_config_files(directory):
    """在指定目录中查找所有配置文件"""
    config_files = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith('.ini') or file.endswith('.cfg'):
                # 使用os.path.join构建完整路径
                full_path = os.path.join(root, file)
                config_files.append(full_path)
    return config_files

# 使用示例
project_dir = os.path.join(os.getcwd(), 'my_project')
configs = find_config_files(project_dir)
print(f"找到 {len(configs)} 个配置文件")
