What is a good way to determine if a URL link is a PDF in Python without looking at the file extension?

Load the first few bytes of the URL and look for the PDF file format magic number.
John Carter
look at the header, you nerd.
Luke Butler
Bytes of the literal string size? I don't know what you mean by load

You might lack some basic understanding of how computers work to finish your homework assignment.

In context of Python, retard
Asher Sanders
Use mimetype library
Lincoln Barnes
yeah.. his point still stands..
Benjamin Howard
If the term "load" doesn't ring a bell you should step away from the computer.
Grayson James
would load be the right verb here? Wouldnt it be get or parse?
Charles Rodriguez
just look at the file extension

Got it, friendo

"Load" isn't even in the context of your meme script. "To load" is a common verb in the English language. Get a dictionary.

>Load the first few bytes of the URL
That's what I'm trying to say. There is no specific method that describes what user is describing.
Jayden Nguyen
Holy fuck, I'm out.

Kys pajeet we're not doing your homework

If someone would tell you to load that pile of sand into a truck, would you also be oblivious?
Ayden Jackson
To get this straight:
File extension is only a Windows meme, you could have PDF ending with EXE name and it would still be opened by PDF reader. To check what the file really is you need to look for characteristic data at the beginning of the file, where header is.

Don't forget to translate "look for" to the context of python. OP has a little problem with this.

Use a HEAD request and check the mimetype. If HEAD is not supported use GET with Byte Ranges and check the file header. If Byte Ranges is not supported abort the connection after downloading the file header. If nothing of this makes sense Google the above terms with keywords such as "http requests" and "PDF file format".

this, although if OP doesn't trust the file extension (or maybe that's not what he meant?) this method still puts trust in the server to report back the correct type.
