Copy directory contents into a directory with python
提问by prosseek
I have a directory /a/b/c that has files and subdirectories. I need to copy the /a/b/c/* in the /x/y/z directory. What python methods can I use?
我有一个包含文件和子目录的目录 /a/b/c。我需要复制 /x/y/z 目录中的 /a/b/c/* 。我可以使用哪些 Python 方法？
I tried shutil.copytree("a/b/c", "/x/y/z"), but python tries to create /x/y/z and raises an error "Directory exists".
我试过了shutil.copytree("a/b/c", "/x/y/z")，但 python 试图创建 /x/y/z 并引发一个error "Directory exists".

I found this code working:
我发现此代码有效：
from distutils.dir_util import copy_tree
# copy subdirectory example
fromDirectory = "/a/b/c"
toDirectory = "/x/y/z"
copy_tree(fromDirectory, toDirectory)

You can also use glob2 to recursively collect all paths (using ** subfolders wildcard) and then use shutil.copyfile, saving the paths
您还可以使用 glob2 递归收集所有路径（使用 ** 子文件夹通配符），然后使用shutil.copyfile，保存路径

The python libs are obsolete with this function. I've done one that works correctly:
这个函数的python库已经过时了。我做了一个工作正常的：
import os
import shutil
def copydirectorykut(src, dst):
os.chdir(dst)
list=os.listdir(src)
nom= src+'.txt'
fitx= open(nom, 'w')
for item in list:
fitx.write("%s\n" % item)
fitx.close()
f = open(nom,'r')
for line in f.readlines():
if "." in line:
shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
else:
if not os.path.exists(dst+'/'+line[:-1]):
os.makedirs(dst+'/'+line[:-1])
copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
f.close()
os.remove(nom)
os.chdir('..')

from subprocess import call
def cp_dir(source, target):
call(['cp', '-a', source, target]) # Linux
cp_dir('/a/b/c/', '/x/y/z/')
It works for me. Basically, it executes shell command cp.
这个对我有用。基本上，它执行 shell 命令cp。
