[Tutor] conditional renaming folder and files in the tree

[banda gunda]

Dear Tutor,


I have made some progress!

But not yet got the results.

Attached is revised code.


Specifically, the problem in below:


for root, dirs, files in os.walk(".", topdown=False):
    for name in files:
        print(os.path.join(root, name))
        os.rename(path + name, path + name.replace("---", "changed"))
        #os.rename(path + "\\"+ name, path + "\\"+ name.replace("---", "changed")
        files[name] = os.sep.join([dirpath, name])

        print (files)

    for name in dirs:
        print(os.path.join(root, name))


.\---DAT1\---DAT3\---000010.txt


---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)
<ipython-input-6-316f0c967a9b> in <module>()
      2     for name in files:
      3         print(os.path.join(root, name))
----> 4         os.rename(path + name, path + name.replace("---", "changed"))
      5         #os.rename(path + "\\"+ name, path + "\\"+ name.replace("---", "changed")
      6         files[name] = os.sep.join([dirpath, name])

FileNotFoundError: [WinError 2] The system cannot find the file specified: 'E://---000010.txt' -> 'E://changed000010.txt'


Thanks once again for your time spent on this.

best,
banda.

Subject: conditional renaming folder and files in the tree


Dear Tutor,

I want to change the name of the folders and the files in the tree.
All those folders and files starting with name string '---'.
Examples:
If a  folder name is : \---DAT1
I want to change this to: \changedDAT1
If a file name is: \---00001.txt
I want to change this to: \changed00001.txt

I have attached the code and output to this email.
Specifically, I like to provide correct syntax (dst / destination) for line 6 code block below!
I have not understood the syntax.

Thanks in advance, for your help .
best,
banda
