VSCode Python adding extra space after % on print when save

Question

I am trying Python with VSCode and it is giving me a headache with formatting. I have te following code:

import os
filePath = "get-file-size.py"

try:
    size = os.path.getsize(filePath)

except OSError:
    print("Path '%s' does not exist or is not accesible", %filePath)
    sys.exit()

print("File size (in bytes): ", size)

VSCode gives me the following error:

invalid syntax (, line 10)

This error happens because it adds an extra space after % in the except print statement as below:

print("Path '%s' does not exist or is not accesible", % filePath)

Can someone point me in the right direction on how to solve this? I am pretty sure it is because a formatter, but how, when, which one?

Thanks in advance

The Vscode Python extension supports source code formatting using autopep8 by default but it can change if you have installed any other formatter. — isAif

Delete the comma before the percent sign:

print("Path '%s' does not exist or is not accesible" % filePath)

The percent sign is the formatting operator. It takes a string on the left and stuff to insert to the string on the right, it's not a separate argument of the print function.

Also, it's better to use str.format:

print("Path '{}' does not exist or is not accesible".format(filePath))

or if you're using python 3.6 and above, use f-strings:

print(f"Path '{filePath}' does not exist or is not accesible")

'%s' but the quotes I think its not necessary

Thank you!!!!! str.format and/or f-strings did the job

I assumed the quotes were to surround the path in the message you print, oh well
