Reason: Window can read files with \, but in the string \ is used as an escape character, after the escape may not find the path of the resource, for example \t will be escaped as tab key
Upper Code:
>>> def func1(path_name):
... import os
... if os.path.exists(path_name):
... return "True"
... else:
... return "False"
...
>>> func1("C:\Users\renyc")#error
File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
>>>
In this example: "C:\Users\renyc" is escaped and the resource of the path is not found.
Solution:
>>> def func1(path_name):
... import os
... if os.path.exists(path_name):
... return "True"
... else:
... return "False"
...
>>> func1(r"C:\Users\renyc")#Add r to declare the string without escaping
'True'
>>> func1("C:\\Users\\\renyc")# handling of absolute paths
'True'
>>>
There are three ways to summarize.
One:Replace the write method with an absolute path func1(“C:\Users\renyc”)
Two: explicitly declare the string without escaping (add r) func1(r “C:\Users\renyc”)
III:Use Linux paths/ func1(“C:/Users/renyc”)
