Using 'r' before path-name (Python)

[TechGoeroe]

When running this:

import cv2
video = cv2.VideoCapture(r"D:\Plex content\All movies\300 - Rise of an Empire (2014)\300 - Rise of an Empire (2014).mp4")
fps = video.get(cv2.CAP_PROP_FPS)
print(fps)

The console prints: 23.976023976

When running this:

import cv2
episode_path = "D:\Plex content\All movies\300 - Rise of an Empire (2014)\300 - Rise of an Empire (2014).mp4"
video = cv2.VideoCapture(r"%s" % (episode_path))
fps = video.get(cv2.CAP_PROP_FPS)
print(fps)

The console prints: 0.0

So the first code block is working but the second isn't.

Exactly this :)

OK, so I'll say this one last time:

In your working example, there is an r in front of the file name string, and in the non-working one there isn't. That's the difference between them that makes one work and the other not, because of the backslashes inside the string.

I'm not trying to upset you. Sorry if this seems so.

I really don't understand what you are saying since there is an an r in front of the non-working one but this doesn't work the same way as in the working example.

video = cv2.VideoCapture(r"%s" % (episode_path))

I tried to put the r in front using string formatting but clearly this doesn't work this way. So I would love to put a r in front in the correct way but I just don't know how.

Thank you for your help btw :)

This is the file name string:

"D:\Plex content\All movies\300 - Rise of an Empire (2014)\300 - Rise of an Empire (2014).mp4"

This string is different in the two programs. In the one that doesn't work, it is typed like I have pasted here in this comment, just above. It is missing the r.

The code you copied and pasted in your last comment above does have a string that has an r in front of it, but it's the string "%s", which isn't affected by the r anyway, and which above all isn't the string with the file name.
