Python_Syntax error: unexpected character after line continuation character

Python_ Syntax error: unexpected character after line continuation character

Reason: the content of the written file is incorrect and should be processed as a string

>>> import os
>>> os.makedirs(time_year+"\\"+time_month+"\\"+time_day)#where time_year, time_month, time_day are all variables with assigned values
>>> os.chdir(time_year\time_month\time_day)# The problem is here, it's not written correctly
  File "<stdin>", line 1
    os.chdir(time_year\time_month\time_day)
                                          ^
SyntaxError: unexpected character after line continuation character

This is OK: os.chdir (time_ year+”\\”+time_ month+”\\”+time_ day)

Refer to the writing method of creating directory in the first line

>>> os.chdir(time_year+"\\"+time_month+"\\"+time_day)#Correct
>>> with open(time_hours+".txt", "w+") as fp:#This method will go to the next step normally
...     fp.read()
