[Tutor] Question about Python.
Hi.
I'm working on Paper, Rock, Scissors in Python.
I need to make it a loop, and test the values (1, 2, 3, /Rock/Paper/Scissors)
yet, but i'm kind of stuck. Could you help me?
import random #Imports the random modual from the library.
def main(): #First function.
print 'Lets play Paper Rock Scissors!\n'
print '1 For Rock\n2 For Paper\n3 For Scissors\n4 To Quit'
number=raw_input ('What do you choose? ') #Gets users input.
pc = ComputerChoice()
PlayerChoice(number, pc)
def ComputerChoice(): #Compuers function
ComputerChoice = random.randrange(1, 4) #Computers random range.
return ComputerChoice
def PlayerChoice(number, CC): #Uses the users input & compares
number = int(number) #With the computers.
print "\n"
if CC == 1 and number == 3:
print 'Computer wins: Rock beats Scissors'
elif CC == 1 and number == 2:
print 'Player wins: Paper beats Rock'
elif CC == 2 and number == 3:
print 'Player wins: Scissors beat paper'
elif CC == 3 and number == 1:
print 'Player wins: Rock beats scissors'
elif CC == 2 and number == 1:
print 'Computer wins: Paper beats rock'
elif CC == number:
print '''Draw!''' #Trying it with 3
elif CC == 3 and number == 2:
print 'Computer wins: Scissors beats rock'
elif number == 4:
print 'Goodbye'
else:
print CC
print number
if number != 4:
print '\n'

In ComputerChoice(), you obtain the choice of the computer.
In PlayerChoice() however, you do not obtain the player choice, but instead
decide on the result.
I would suggest to modify PlayerChoice() to just obtain the player choice
(code which you now have in main()).
Next write a new function that takes the computer choice and the player
choice, and decides on the outcome.
(that function should have 3 possible return values).
Then in the main loop combine all three functions.
The construct you should investigate seems the 'while' statement.
(while the game is not decided, call the functions)
Sincerely,
Albert

What exactly puzzles you? You know you need
a loop so you presumably realize that you need
to repeat some part of your program.
What bit needs to be repeated?
Is it the bit that you ask the platyer to choose a value?
Or where the computer calculates a value?
Or where you work out the result? Or all of these?
And how many times, or until what condition, should it repeat?
How will you detect that value?
If you answer those questions you might start to see
what needs to be done?
There are a few commens on the code below:
def main(): #First function.
print 'Lets play Paper Rock Scissors!\n'
print '1 For Rock\n2 For Paper\n3 For Scissors\n4 To Quit'
number=raw_input ('What do you choose? ') #Gets users input.
number sems a bit vague, this is actually the players choice.
So call it PlayersChoice or some such descriptive name.
Even just pc maybe - see below...
pc = ComputerChoice()
And pc seems an odd name to choose for ComputersChoice()
Why not cc?
PlayerChoice(number, pc)
And this function doesn't actually return the players choice,
it displays the result. So maybe DisplayResult wouldbe a
better name?
def ComputerChoice(): #Compuers function
ComputerChoice = random.randrange(1, 4) #Computers random range.
return ComputerChoice
Its not a good idea to use a variable name the same as the function.
This will prevent you using recursion (which you might not know
about yet but is important later!) You could simply use 'choice', its
shorter to type too!
def PlayerChoice(number, CC): #Uses the users input & compares
number = int(number) #With the computers.
Its probably better to convert the number where you read it from
the user - that way you can tell them they made a mistake and
get a better response before you call this function. And the function
can just expect a number as input.
print "\n"
if CC == 1 and number == 3:
print 'Computer wins: Rock beats Scissors'
elif CC == 1 and number == 2:
print 'Player wins: Paper beats Rock'
elif CC == 2 and number == 3:
print 'Player wins: Scissors beat paper'
elif CC == 3 and number == 1:
print 'Player wins: Rock beats scissors'
elif CC == 2 and number == 1:
print 'Computer wins: Paper beats rock'
elif CC == number:
print '''Draw!''' #Trying it with 3
elif CC == 3 and number == 2:
print 'Computer wins: Scissors beats rock'
elif number == 4:
print 'Goodbye'
OK, This is stuff you probably want to take out and put
beside the code for reading the user input. Its not really
part of the game. In fact this might be what you use to
terminate your loop?
else:
print CC
print number
if number != 4:
print '\n'
main()
Looks like you discovered recursion already, although
I suspect you don't know it yet? :-)

Also Could anyone explain how Swig > bindings work? There are quite a few options: SIP, SWIG and ctypes (in the std lib) build wrappers for C libraries. http://www.scipy.org/Weave lets you include C++ in a Python module. boost::python wraps C++ libraries. Pyrex and Cython compile Python-like source code to C extensions. I haven't used any of these and can't tell you much about them. Google will get you more info.

Re: [Tutor] Using C in python
There's a section in the Python docs just on this topic: http://docs.python.org/extending/index.html There's probably also some stuff in the wiki, although I'm not familiar with anything specific: http://wiki.python.org/moin/ The SWIG documentation is extensive, and while not the user-friendliest, should get you started: http://www.swig.org/doc.html The quick intro to SWIG is that you create and "interface file" which defines how Python interfaces to your C code. In the braindead simple cases, this can be simply the header files with your function prototypes. In actual usage, it's a good deal more complicated, but the SWIG docs show you the way.

Here is a short example that uses Cython to call a couple of C functions in
OpenGL and libc ("math.h"). The functions are declared in the "cdef extern"
blocks at the top.

Re: [Tutor] Using C in python
"amit sethi" wrote what are the ways in which i can use C in python programs . You can't use C directly what you can do is access libraries written in C. In fact quite a few of the standard libraries are written that way. So it depends what you want to do. If you have C source code that you want to execute from Python you can either:: a) Build a library and create a Python wrapper so it looks like a module b) Build an executable file and call that using subprocess/popen etc c) If its one of the common C libraries or a Windows DLL you can probably use an existing framework to call it. For example ctypes will access a lot of stuff. If you want to execute Python code from a C program, you can do that too, but it doesn't sound like thats what you need? SWIG bindings are there any other . Also Could anyone explain how Swig bindings work? SWIG bindings just expose C code in the right format for Python to see the code as a Python module. Its slightly easier than doing it by hand in C because it automates what is a pretty brain dead repetitive process. ( I've only used SWIG with Tcl but I assume its a similar process for Python.)
