Use a dictionary that maps your commands to the relevant functions, then
call the function using the dictionary. This gives the idea (hopefully):

def command1func(): print "a"
def command2func(): print "b"
commands = {'command1': command1func, 'command2': command2func}

curcmd = 'command1'
if curcmd in commands.keys():
    commands['command1']()
else:
    print "illegal command"
