cd command in terminal is not working.

I have started programming python using geany but I want to get used to using python based commands on the terminal. The thing is i can't even use them yet because the cd command doesn't seem to want to work. I created a folder called Python to store all of my python project folders, and I tried using cd in one of two ways:
cd ~/python
cd home/brandon/python
Both times it says the directory doesn't exist. I am using ubuntu through the wubi installer if that helps at all.
