os.system('pause') on windows not working in pycharm

i have a line at the end of my script 

os.system('pause') 

that on windows OS displays in the console in pycharm as "Press any key to continue . . . "

yet in the console tab in debug, i can't seem to press any key to continue and i have to end up clicking Stop from the Run menu in PyCharm which forces my program to exit with -1 :(

is there some setting i need to change in PyCharm so that i can cleaning press any key to have it exit properly ? this works fine in window cmd line window but just not in PyCharm
