I have some code that sets the working directory, then saves a file name as a variable, incorporating the current date into the filename:
os.chdir(r"C:\Users\me\Documents")
filename = "My_file_" + str(date.today()) + ".xlsx"
I want to concatenate these into a full filepath with a backslash, like this:
C:\Users\me\Documents\My_file_2022-09-23.xlsx
I’ve tried to do this with no success. This code doesn’t work because it thinks "+ filename" is a string; it returns the error "string literal is unterminated":
filepath = os.getcwd() + r'\' + filename
Adding another backslash to terminate the string removes the error and gets it to understand that filename is a variable, but I then get both backslashes in the result, as shown below:
filepath = os.getcwd() + r'\\' + filename
C:\Users\me\Documents\\My_file_2022-09-23.xlsx
Does anyone know how to get the desired result, please?
>Solution :
A better way to join paths is through os.path.join(), which will use a backslash or forward slash depending on the platform convention (backslash on Windows, forward slash on Unix including Linux and Mac):
filepath = os.path.join(os.getcwd(), filename)
The cause of the "unterminated string literal" error is that raw strings can’t end with a backslash. Using '\\' without the r works fine.
