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
