Python批量修改文件名操作指南(文件名的替换、前缀、后缀的添加)

import os

def replace_in_filenames(directory, old_str, new_str):
    for filename in os.listdir(directory):
        if old_str in filename:
            new_filename = filename.replace(old_str, new_str)
            os.rename(os.path.join(directory, filename), os.path.join(directory, new_filename))

# 示例用法
replace_in_filenames('/path/to/directory', 'old_string', 'new_string')

import os

def add_prefix_suffix(directory, prefix, suffix):
    for filename in os.listdir(directory):
        new_filename = prefix + filename + suffix
        os.rename(os.path.join(directory, filename), os.path.join(directory, new_filename))

# 示例用法
add_prefix_suffix('/path/to/directory', 'prefix_', '_suffix')

import glob

files = glob.glob('/path/to/directory/*.txt')  # 匹配所有以.txt结尾的文件

import glob
import os

def rename_files(directory, pattern, new_name):
    files = glob.glob(os.path.join(directory, pattern))
    for old_file in files:
        new_file = os.path.join(directory, new_name)
        os.rename(old_file, new_file)

# 示例用法
rename_files('/path/to/directory', '*.txt', 'new_name.txt')

import shutil

def move_and_rename(source, destination):
    shutil.move(source, destination)

# 示例用法
move_and_rename('/path/to/source/file.txt', '/path/to/destination/new_file.txt')

import os
import re

def rename_with_regex(directory, pattern, replacement):
    for filename in os.listdir(directory):
        new_filename = re.sub(pattern, replacement, filename)
        os.rename(os.path.join(directory, filename), os.path.join(directory, new_filename))

# 示例用法：将所有数字移动到文件名末尾
rename_with_regex('/path/to/directory', r'(\d+)(.*)', r'\2\1')

import os
import datetime

def rename_with_metadata(directory):
    for filename in os.listdir(directory):
        filepath = os.path.join(directory, filename)
        created_time = os.path.getctime(filepath)
        modified_time = os.path.getmtime(filepath)
        
        # 将时间戳转换为日期字符串，例如：2023-01-15_12-30-45
        created_date = datetime.datetime.fromtimestamp(created_time).strftime('%Y-%m-%d_%H-%M-%S')
        modified_date = datetime.datetime.fromtimestamp(modified_time).strftime('%Y-%m-%d_%H-%M-%S')
        
        new_filename = f"created_{created_date}_modified_{modified_date}.txt"
        os.rename(filepath, os.path.join(directory, new_filename))

# 示例用法：根据文件的创建和修改时间修改文件名
rename_with_metadata('/path/to/directory')

import os

def rename_files_in_subdirectories(directory, pattern, replacement):
    for root, _, files in os.walk(directory):
        for filename in files:
            if re.search(pattern, filename):
                new_filename = re.sub(pattern, replacement, filename)
                os.rename(os.path.join(root, filename), os.path.join(root, new_filename))

# 示例用法：在所有子文件夹中批量修改文件名
rename_files_in_subdirectories('/path/to/parent_directory', r'pattern', r'replacement')
