Hi John,
I came to python with only some ill-recalled BASIC, and I also
(initially) missed goto, etc. You'll get over it :-)
See if the examples below give you a push. (I've purposely chosen ones
silent on the die-rolling logic.)
>>> def doit():
print "Working!"
>>> for i in range(6):
doit()
Working!
Working!
Working!
Working!
Working!
Working!
>>>
That is a minimal way to define some action and do it repeatedly. You
will also need to return some value for your use case. So consider:
>>> def getit():
val = raw_input("Gimme!\n")
return val
>>> vals = []
>>> for i in range(3):
vals.append(getit())
Gimme!
righty'oh
Gimme!
I did
Gimme!
OK
>>> vals
["righty'oh", 'I did', 'OK']
>>>
HTH,
Brian vdB
