Shutil.copytree ----> Windows错误： [错误 3] 系统找不到指定的路径：

Question

我正在尝试从源文件中提取内容并移动到目标文件夹中。

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)

我也尝试过这条路。

#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))

使用copytree时，两条路径都出现此错误

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

请帮忙。

以下内容适用于Python 3.6，请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Windows的任何磁盘。在此处列出默认环境变量

f"{expression}"表示法被称为f字符串。这是在Python 3.6中引入的，这里是PEP。在括号内加上:02会使数字的开头为0。
