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

Question

我正在尝试从源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，两条路径均出现此错误

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

请帮忙。

以下在 Python 3.6 中对我有用，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。 在这里列出默认环境变量

f"{expression}"表示法称为 f 字符串。 这是在 Python 3.6 中引入的，这里是 PEP 。 在括号内添加:02使数字前导 0。
