I have a string that contains the path to a file, how to change the path

Question

I use google clould storage api. I get the filename like this 'pdf/randomPdf.pdf'

I use

new_filename = Path(file_name).stem + ".txt"

I do this so I can change the name of the extension to .txt

Now I want to change the 'pdf/...' to 'text/...'

How I can do it without split?

*"without split"*. Your code (if works) is not using any splits. — Austin, Jun 03 '19 at 17:40
Please be more clear. Do you want the file to exist in a new location, or want to manipulate the string only? — jsarbour, Jun 03 '19 at 17:41
What do you have against using split? why does it not work for you? — jsarbour, Jun 03 '19 at 17:41
`newFilename = filename.replace('pdf/', 'text/').replace('.pdf', '.txt')` — John Gordon, Jun 03 '19 at 17:42
@JohnGordon your solution worked fine, if you want to submit your answer so I can solve the problem — Iakovos Belonias, Jun 03 '19 at 18:12

These answers 1 and 2 seem relevant to your question -

You can use os.path.splitext(filename) to extract everything but file extension - pdf/pdfFile in your case.

You can use os.path.dirname(filename) to extract the head - pdf in your case.

You can use os.path.basename(filename) to extract the tail - pdfFile.pdf in your case.

Have you tried os.rename()?

Just do

os.rename("pdf/pdfFile.pdf", "text/pdfFile.txt")

Use the string built-in method replace().

newFilename = filename.replace('pdf/', 'text/').replace('.pdf', '.txt')
