how can i change only the first letter of a filename into uppercase?

Question

import os

def soldier(ppth):
            pth= os.listdir(ppth)
            for filename in pth:
                os.rename(filename,filename.lower())
            print(pth)
soldier("D://QwertyA")

Even if i use os.rename(filename,filename.capitalize()). Its generating an error FileNotFoundError: [WinError 2] The system cannot find the file specified: 'asd.docx' -> 'Asd.docx' — BABA ADAM, May 14 '21 at 21:13
You probably need to use the full path to the file `f"{ppth}/{filename}"` — cam, May 14 '21 at 21:22

You can use the capitalize method.

string.capitalize()

def soldier(ppth):             
    pth= os.listdir(ppth)             
    for filename in pth:                 
        os.rename(f"{ppth}/{filename}",f"{ppth}/{filename.lower().capitalize()}")

Right. ```import os def soldier(ppth): pth= os.listdir(ppth) for filename in pth: os.rename(filename,filename.lower().capitalize()) print(pth) soldier("D://QwertyA") ``` – cam May 14 '21 at 21:13
This is exact what i want – BABA ADAM May 14 '21 at 21:38

You can try something like this.

import os
fileName = 'test.txt'
newFileName = fileName.capitalize()
print(newFileName)
os.rename(f'/path/to/file/{fileName}',f'/path/to/file{newFileName}')

Seems like my file has been capitalized.
