newbie questions

[john boy]

have a few questions...i'm a newbie....so i'd appreciate any help
 
1- what is the difference between Python GUI and Python command line?
 
2-in Python command line when I hit enter after typing a command I cannot go back and "delete" "backspace" or otherwise edit a previous command...why?
 
3-I have tried the following example from "how to think like a computer scientist"
 
def makeline():
    print
 
print "firstline"
makeline()
print "secondline"
 
problem is....whenever I type -print "firstline"- and then hit enter...well it follows the command and gives "firstline"
EX.
print "firstline"
firstline
 
instead of giving me a chance to type in -makeline()-  
and thus completing the example
 
Anybody help here?? thanks -xray-
