python 批量更改文编码

import os

# 更改文件编码
def recoding(filename):
    try:
        with open(filename, 'r', encoding = 'gbk') as fr:
            doc = fr.read()
        with open(filename, 'w', encoding = 'utf-8') as fw:
            fw.write(doc)
    except UnicodeDecodeError:
        print(filename + " 不是 GBK 编码")

# 扫描指定目录及子目录下所有文件
def fscan(path, filepaths):
    for root, dirs, files in os.walk(path):         # 获取目录下所有文件，文件夹信息
        for file in files:                          # 遍历文件信息
            if '.cpp' in file:                      # 如果是 .cpp 文件
                filepath = os.path.join(root, file) # 添加完整路径
                filepaths.append(filepath)

if __name__ == "__main__":
    filepaths = []
    # 获取目录下所有文件
    fscan("D:\\Hello", filepaths)
    # 更改文件编码
    for file in filepaths:  
        recoding(file)

python 批量更改文件名

import os

if __name__ == "__main__":
    files = os.listdir("./")
    for file in files:
        if ".jpg" in file:
            name, type = file.split(".")
            os.rename(file, name + ".png")
