Now, we are going to learn about os.path(). It is used for path manipulations. In this section, we will look at some of the functions that the os module offers for pathnames.

Start the python3 console:

>>> os.path.basename('/home/student/work/sample.txt')
'sample.txt'

• os.path.exists(path): Returns True if path refers to the existing path.

>>> os.path.exists('/home/student/work/sample.txt')
True

• os.path.getsize(path): Returns the size of the entered path in bytes.

39
