IOError: [Errno 22] 无效模式 ('rb') 或文件名

Question

我是 python 的初学者，并尝试使用一个非常简单的 shutil 模块 (shutil.copy) 将数据库从多个文件夹复制到备份文件夹中。我收到以下错误。任何帮助表示赞赏。

# importing os module  
import os

#import time module
import time
import datetime

# importing shutil module  
import shutil 


now = datetime.datetime.now()
timestamp = str(now.strftime("%Y%m%d_%H%M%S"))

source5 = "F:/SHARED/SOP/PRE GO LIVE/TEST CASES & SCENARIOS/MASTER/PRE_GO_LIVE_MASTER.accdb"

dest5 = "F:/SHARED/SOP/SB/Python/Destination/PRE_GO_LIVE_MASTER.accdb_"+timestamp+".accdb" 

print("Before copying ")

DB5 = shutil.copy(source5,dest5)

print("After DATABASE has been copied")

Error:
Traceback (most recent call last):
  File "C:\Users\sbasava1\Desktop\Python\Final_Attempt.py", line 101, in <module>
    DB5 = shutil.copy(source5,dest5)

    copyfile(src, dst)

检查您的文件路径，使用 双 反斜杠 \\ 或 单 正斜杠 / 或将您的字符串设为原始字符串 r"..."。

# Original path - wouldn't work
path = "c:\location\directory"

# Raw string - would work
path = r"c:\location\directory"

# Double slashes - would work
path = "c:\\location\\directory"

# Forward slashes - would work
path = "c:/location/directory"

考虑了解string literals

如果这没有帮助给我留下评论，那么查看您正在使用的代码的/部分也将有所帮助！

编辑：运行你的脚本并没有给我带来问题：

检查您尝试在其中创建文件的目录是否确实存在
