【python初级】 shutil.move移动文件或目录

nginx0、背景

shutil.move可以实现文件或者目录的移动。

move(src, dst, copy_function=<function copy2 at 0x000001D1CE15F8C8>)
    Recursively move a file or directory to another location. This is
    similar to the Unix "mv" command. Return the file or directory's
    destination.
    
    If the destination is a directory or a symlink to a directory, the source

    exist.
    
    If the destination already exists but is not a directory, it may be
    overwritten depending on os.rename() semantics.
    
    If the destination is on our current filesystem, then rename() is used.
    Otherwise, src is copied to the destination and then removed. Symlinks are
    recreated under the new name if os.rename() fails because of cross
    filesystem renames.
    
    The optional `copy_function` argument is a callable that will be used
    to copy the source or it will be delegatclickhouseed to `copytree`.
    By default, copy2() is used, but any function that supports the same
    signature (like copy()) can be used.
    
    A lot more could be done here...  A look at a mv.c shows a lot of
    the issues this implementation glosses over.

1、移动目录

shutil.move(old,new)用来移动:文件夹:

old 是一个目录
new 是一个存在的目录消费电子,这时会把old目录移动到new下面;可以new也可以是一个不存在的目录,这时会创建这个不存在的目录,然后把old目录下面的所有文件移动到创建的目录里面。STM32CubeMX

举例:

import shutil
# 移动目录
shutil备忘录微信小程序.move("./fvimolder_123","./folder_456")

./folder_123:
——————-目录一定要存在,否则报错;

./folder_456:
——————-目录不存在时,创建该目录导航条,并将./folder_123目录下的文件移动到./folder_456目录下;
——————-目录存在时,将folder_123文件夹移动到folder_45uvc6文件夹内;

2、移动文件

shutil.move(old,new)用来移动:文件:

jira

old 是一个文件路径
new new是一个存在的文件夹路径或是一个存在的文件夹路径加文件名

注意:
new如果是一个不存在的文件LSTNet夹路径,则会将原文件移动到new文件夹上一目录中,且以该文件夹的名字重命名。
new如果是一个不存在的文件夹路径加文件名,则会报错。

举例:

devopsimport shutil
# 移动文件
shutil.move("./maskpython基础知识/sample.jpg","./folder_456/folder_789")

./mask/sample.jpg:
——————-路径一定要存在,否则报错;

./folder_456/folder_789:
——————-目录存在时,将./mask/sample.jpg文件移动到./folder_456/folder_789目录下;
——————-目录不存在时,具体:folder_456存在,folder_789不存在时,将./mask/sample.jpg移动到folder_456文件夹下,并将sample.jpg文件改名为folder_789;
——————-目录不存在时,具体:folder_456不存在,folder_789不存在时,报错!
