Question

我可以使用os.rename（）重命名文件而没有任何问题/错误。

但是当我尝试重命名添加时间戳的文件时，它会抛出win3错误或win123错误，尝试所有组合但没有运气，任何人都可以提供帮助。

成功代码：

#!/usr/bin/python
import datetime
import os
import shutil
import json
import re


maindir = "F:/Protocols/"
os.chdir(maindir)
maindir = os.getcwd()
print("Working Directory : "+maindir)
path_4_all_iter = os.path.abspath("all_iteration.txt")
now = datetime.datetime.now()
timestamp = str(now.strftime("%Y%m%d_%H:%M:%S"))
print(type(timestamp))
archive_name = "all_iteration_"+timestamp+".txt"
print(archive_name)
print(os.getcwd())
if os.path.exists("all_iteration.txt"):
    print("File Exists")
    os.rename(path_4_all_iter, "F:/Protocols/archive/archive.txt")
    print(os.listdir("F:/Protocols/archive/"))

print(os.path.abspath("all_iteration.txt"))

记录：

E:\python.exe C:/Users/SPAR/PycharmProjects/Sample/debug.py
Working Directory : F:\Protocols
<class 'str'>
all_iteration_20180409_20:25:51.txt
F:\Protocols
File Exists
['archive.txt']
F:\Protocols\all_iteration.txt

Process finished with exit code 0

错误代码：

    print(os.getcwd())
if os.path.exists("all_iteration.txt"):
    print("File Exists")
    os.rename(path_4_all_iter, "F:/Protocols/archive/"+archive_name)
    print(os.listdir("F:/Protocols/archive/"))

print(os.path.abspath("all_iteration.txt"))

错误日志：

Answer 1

您的时间戳格式中包含冒号，Windows文件名中不允许使用冒号。看到关于该主题的答案：

如果您将时间戳格式更改为：

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

它应该有用。

Answer 2

您无法将:作为文件名的一部分

更改

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

到

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

您可以重命名文件
