Python 批量压缩同名文件- 编程源码 -卓越飞翔博客

在工作中可能会遇到下面的场景：需要将很多同名的文件压缩到一个压缩包里面，几千个文件手动肯定不现实，
那就用代码实现把

import os
from zipfile import ZipFile
 
def zip_files_with_same_name(folder_path, output_folder):
    
    os.makedirs(output_folder, exist_ok=True)
 
    # 遍历文件夹及其子文件夹
    for root, _, files in os.walk(folder_path):
        # 创建一个字典，以文件名（不包含后缀）为键，文件路径列表为值
        file_dict = {}
        for file in files:
            file_name, file_ext = os.path.splitext(file)
            file_key = file_name.lower()  # 忽略文件名的大小写
            file_path = os.path.join(root, file)
            if file_key in file_dict:
                file_dict[file_key].append(file_path)
            else:
                file_dict[file_key] = [file_path]
 
        # 遍历字典，对每组同名文件进行压缩
        for key, file_paths in file_dict.items():
            if len(file_paths) > 1:
                
                rel_path = os.path.relpath(file_paths[0], folder_path)
 
                output_subfolder = os.path.join(output_folder, os.path.dirname(rel_path))
 
                 
                os.makedirs(output_subfolder, exist_ok=True)
 
                 
                zip_file_path = os.path.join(output_subfolder, f"{key}.zip")
 
                with ZipFile(zip_file_path, 'w') as zipf:
                    for file_path in file_paths:
                         
                        rel_file_path = os.path.relpath(file_path, folder_path)
                        zipf.write(file_path, rel_file_path)
 
if __name__ == "__main__":
  
    current_folder = os.getcwd()
 
   
    output_folder = os.path.join(current_folder, "output")
 
    # 执行压缩
    zip_files_with_same_name(current_folder, output_folder)

这个代码可以将目录下所有文件夹下的同名文件压缩在一起，并保留文件路径
还有两个分别是只压缩当前文件夹下的文件、压缩所有文件夹下的文件，不保留文件路径
批量压缩同名文件(目录下文件).py

import os
from zipfile import ZipFile

def zip_files_with_same_name(folder_path, output_folder):
    # 获取文件夹下的所有文件
    files = [f for f in os.listdir(folder_path) if os.path.isfile(os.path.join(folder_path, f))]

    # 创建一个字典，以文件名（不包含后缀）为键，文件路径列表为值
    file_dict = {}
    for file in files:
        file_name, file_ext = os.path.splitext(file)
        file_key = file_name.lower()  # 忽略文件名的大小写
        file_path = os.path.join(folder_path, file)
        if file_key in file_dict:
            file_dict[file_key].append(file_path)
        else:
            file_dict[file_key] = [file_path]

    # 创建输出文件夹（如果不存在）
    os.makedirs(output_folder, exist_ok=True)

    # 遍历字典，对每组同名文件进行压缩
    for key, file_paths in file_dict.items():
        if len(file_paths) > 1:
            zip_file_path = os.path.join(output_folder, f"{key}.zip")
            with ZipFile(zip_file_path, 'w') as zipf:
                for file_path in file_paths:
                    zipf.write(file_path, os.path.basename(file_path))

if __name__ == "__main__":
    # 获取当前工作目录
    current_folder = os.getcwd()

    # 输出文件夹直接设置为当前工作目录下的 "output" 文件夹
    output_folder = os.path.join(current_folder, "output")

    # 执行压缩
    zip_files_with_same_name(current_folder, output_folder)

批量压缩同名文件5 (所有文件夹，压缩包里面不保留文件路径).py

import os
from zipfile import ZipFile

def zip_files_with_same_name(folder_path, output_folder):
    os.makedirs(output_folder, exist_ok=True)

    for root, _, files in os.walk(folder_path):
        file_dict = {}
        for file in files:
            file_name, file_ext = os.path.splitext(file)
            file_key = file_name.lower()
            file_path = os.path.join(root, file)
            if file_key in file_dict:
                file_dict[file_key].append(file_path)
            else:
                file_dict[file_key] = [file_path]

        for key, file_paths in file_dict.items():
            if len(file_paths) > 1:
                rel_path = os.path.relpath(file_paths[0], folder_path)
                output_subfolder = os.path.join(output_folder, os.path.dirname(rel_path))
                os.makedirs(output_subfolder, exist_ok=True)
                zip_file_path = os.path.join(output_subfolder, f"{key}.zip")

                with ZipFile(zip_file_path, 'w') as zipf:
                    for file_path in file_paths:
                        # Write each file without including the file path
                        zipf.write(file_path, os.path.basename(file_path))

if __name__ == "__main__":
    current_folder = os.getcwd()
    output_folder = os.path.join(current_folder, "output")
    zip_files_with_same_name(current_folder, output_folder)
