Insert / edit overwriting code


I am editing code in the Pycharm editor, I can't insert/amend text without it overwriting 


for example, if I wanted to change the last two digits of this MAC this line ("ifconfig wlan0 hw ether 11:22:33:44:55:66", shell =True) I would delete the 66 and replace it with say 44 but it overwrites, shell =True) 

I want to be able to insert/edit without this occurring
