Shutil.copytree ----> WindowsError: [Error 3] The system cannot find the path specified:

Question

我正在尝试从源中提取内容并移至目标文件夹。

folder1 = 2018
folder2 = 8    
folder3 = 3
    source = os.path.join("C:\","Pizza","Sammy","Logs", "Archive", "DataLog_Private" ,str(folder1),"0" + str(folder2),"0" + str(folder3))

    destination = os.path.join("C:\","Users", "alex", "Desktop", "logPull" , "DataLog_Private" ,str(folder1),"0" + str(folder2),"0" + str(folder3))

shutil.copytree(source,destination)

这条路我也试过

#source = r"C://Pizza//Sammy//Logs//Archive//DataLog_Private//%s//%s//%s//" %(str(folder1),"0" + str(folder2),"0" + str(folder3))
#destination = r"C://Users//alex//Desktop//logPull//DataLog_Private//%s//%s//%s//" %(str(folder1),"0" + str(folder2),"0" + str(folder3))

在使用 copytree

时，我在两条路径上都遇到了这个错误

WindowsError: [Error 3] The system cannot find the path specified'C:\Pizza\Sammy\Logs\Archive\DataLog_Private\2018\08\03/*.*'

请帮忙。

以下是我在Python3.6下的作品，注意环境变量的使用。

import os
import shutil

folder1 = 2018
folder2 = 8    
folder3 = 3

drive = os.path.join(os.getenv("HOMEDRIVE"), os.sep)
date_path = os.path.join(f"{folder1}", f"{folder2:02}", f"{folder3:02}")

source = os.path.join(
    drive, "Pizza","Sammy", "Logs", "Archive", "DataLog_Private", date_path
)
destination = os.path.join(
    os.getenv("USERPROFILE"), "Desktop", "logPull", "DataLog_Private", date_path
)

shutil.copytree(source, destination)

HOMEDRIVE 应该指向安装了 Windows 的任何磁盘。列出 if 默认环境变量 here

f"{expression}" 符号称为 f 字符串。这是在 Python 3.6、here's the PEP 中引入的。在方括号内添加 :02 会给数字一个前导 0。
