I am doing the following:
import os
ii = r'Z:\Monthly\iOT\2021'
dir0 = os.path.splitdrive(ii)[1]
dir1 = os.path.join(r'G:', r'My Drive', dir0)
print(dir1) gives 'G:\\Monthly\\iOT\\2021' and completely ignores 'My Drive'. I understand it has something to do with two backslashes in front of dir0 but not sure how to remove it.
I was expecting
'G:\\My Drive\\Monthly\\iOT\\2021'
You can do as following
os.path.join('G:\\', r'My Drive', dir0[1:])
This "slices" the result of dir0, getting the characters from index 1 to the end of the string
This will result in
'G:\\My Drive\\Monthly\\iOT\\2021'
Remember the following, as stated in the docs
On Windows, the drive letter is not reset when an absolute path component (e.g., r'\foo') is encountered. If a component contains a drive letter, all previous components are thrown away and the drive letter is reset. Note that since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.
