full_file_name = os.path.join(src, file)

This line of code joins the `src` directory path and the `file` name to create the full file path. It concatenates the two strings using the appropriate file path separator for the operating system. For example, on Windows, this would use backslashes (\) as the separator, while on Unix-based systems it would use forward slashes (/).
The resulting `full_file_name` variable would contain the full path to the file, which can then be used to perform operations on that file, such as reading its contents or copying it to a new location.

def copy_files(src, dest): src_files = os.listdir(src) for file_name in src_files: full_file_name = os.path.join(src, file_name) if os.path.isfile(full_file_name): shutil.copy(full_file_name, dest)
这个函数`copy_files`的作用是将源目录(src)中的所有文件复制到目标目录(dest)中。具体实现如下:
1. 使用`os.listdir(src)`获取源目录中的所有文件和文件夹的名称。
2. 对于每个文件名(file_name)进行循环处理。
3. 使用`os.path.join(src, file_name)`将源目录和文件名拼接成完整的文件路径(full_file_name)。
4. 使用`os.path.isfile(full_file_name)`检查该路径是否为一个文件。
5. 如果是文件,则使用`shutil.copy(full_file_name, dest)`将文件复制到目标目录中。
这个函数依赖于`os`和`shutil`模块,因此在使用之前需要先导入它们。这个函数可以方便地实现将一个目录下的所有文件复制到另一个目录中的操作。

好的,根据你的要求,将以上代码修改为将修改后的文件命名恢复原来的命名,可以按照以下方式修改:
```
import os
from datetime import datetime
import random
import string
def restore_original_names(folder_path):
"""
批量将文件名恢复为原来的名称,需要在修改文件名之前备份原来的名称
:param folder_path: 文件夹路径
"""
for filename in os.listdir(folder_path):
full_path = os.path.join(folder_path, filename)
if os.path.isfile(full_path):
# 获取备份的文件名
backup_filename = os.path.splitext(filename)[0] + ".bak"
backup_full_path = os.path.join(folder_path, backup_filename)
if os.path.exists(backup_full_path):
# 将备份的文件名恢复为原来的文件名
os.rename(backup_full_path, full_path)
def batch_rename_files(folder_path, random_string_length=0):
"""
批量重命名文件,名字改为该文件的创建或修改日期,如果有重名的文件,可以添加一个随机字符串
:param folder_path: 文件夹路径
:param random_string_length: 随机字符串长度,默认为0
"""
# 先将文件名备份
for filename in os.listdir(folder_path):
full_path = os.path.join(folder_path, filename)
if os.path.isfile(full_path):
# 获取文件的后缀名
file_extension = os.path.splitext(filename)[1]
# 备份原来的文件名
backup_filename = os.path.splitext(filename)[0] + ".bak"
backup_full_path = os.path.join(folder_path, backup_filename)
os.rename(full_path, backup_full_path)
# 批量重命名文件
for filename in os.listdir(folder_path):
full_path = os.path.join(folder_path, filename)
if os.path.isfile(full_path):
# 获取文件的创建时间或修改时间
timestamp = os.path.getmtime(full_path)
# 格式化时间
date_time = datetime.fromtimestamp(timestamp)
new_name = date_time.strftime("%Y-%m-%d %H-%M-%S")
# 添加随机字符串
if random_string_length > 0:
random_string = ''.join(random.choices(string.ascii_lowercase + string.digits, k=random_string_length))
new_name += '-' + random_string
# 拼接新的文件名
new_filename = new_name + file_extension
new_full_path = os.path.join(folder_path, new_filename)
# 重命名文件
os.rename(full_path, new_full_path)
# 将文件名恢复为原来的名称
restore_original_names(folder_path)
if __name__ == '__main__':
folder_path = 'your_folder_path'
batch_rename_files(folder_path, random_string_length=5)
```
这个修改后的代码首先会备份原来的文件名,然后批量重命名所有的文件,并最后将所有文件的名字恢复为原来的名称。
