Is you powershell code printing the file being removed ? does it remove the file as well ?
Because when you say "I would *just* do" you seem to imply that the same actions can be performed with powershell in very few lines.
Anyway, your python code is correct but contain minor issues:
1/ listdir returns all elements in a directory, including subdirectories, you should filter the list to get only files. os.remove will not remove directories.
2/ activefile = os.path.join(objdir, f) # would be the portable way of joining path elements
objdir = os.path.join('C:', 'temp2')
for f in [f for _f in os.listdir(objdir) if os.path.isfile(_f)]:
Also note that 'shutil' is a module giving you access to a lot of tools for copying, deleting creating files/dir.
