python os.chdir() cant be used multiple times?

when I first use the os.chdir() it works then when I try using it again it does not and give me an error. the following files have been created. ed and 123 

import os 
os.mkdir('ed')
os.mkdir('123')

now i want to change between the two.

import os
os.chdir('ed')

os.chdir('123')

Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
os.chdir('123')
FileNotFoundError: [WinError 2] The system cannot find the file specified: '123'

why wont it let me change between the two files ?

Think of calling os.chdir(some_path) the same as doing cd some_path from the terminal. It considers the provided path to be relative unless being explicitly given an absolute path (starting with drive letter on Windows or / on Linux).

for os.chdir('ed') ; os.chdir('123') to work 123 dir must be a subdir of ed. In your case it is not, so you will either need to:

  1. provide absolute path

  2. go back one level before calling os.chdir('123'):

    os.chdir('..')
os.chdir('123')

    or even 

    os.chdir('..{}123'.format(os.path.sep))

    Note the use of os.path.sep in order to avoid using OS specific path separator.

After creating ed and 123 folder, these two folders are at same level. 

os.chdir('ed')

Above line will point you into ed folder.

os.chdir('../123')

You need to use .. to navigate to parent folder and then navigate to 123 folder.
