Re: beginner: using parameter in functions

thanks very much John!

so i can have self as function parameter as well as in a method.
that allowed me to use properties to retrieve the value set in the
constructor.
i just changed the function return statement and it worked.
i was working along these lines but couldnt get it up and running as
fast as you posted.

templating sure is a great way to create dynamic query strings.

very cool so far but still lots to learn.

thanks again,
jim

hi-

i am having trouble using parameter values in my function and to be
honest a
little trouble with
member variables. i am trying to pass in the argument 'd' representing
delete.
what the code will do is if it is 'd' it will make a delete query
template
string.
if it is an 'i' then insert query etc.

this is the results of my attempt to print the contents of the parameter
values.
<__main__.getQryStr instance at 0x01151D50> ('d',) me mad


(and on a side note if i dont include the *args i get an invalid number
of
parameters supplied message.)
why is it returning the value in this format ('d',) ?
i cant get x == d
i guess that value 'd' is stored in a tuple and i'd like to get it out of
there.

so basically the function returns nope as it stands

python is sure different from other languages i have used.

thanks for any help,
jim



Try, the following:

class getQryStr:
def __init__(self,op):
print op
self.x = 'd'
def returnStr(self, *args):

print '%s %s me mad' % (self.x,args)
if self.x == 'd':
s = Template("delete from columndef where tblid = $tblid and
colname = $colname")
else:
return 'nope' #this else is just for illustration and
testing

d = dict(tblid=t.tblid.getText(), colname=t.colName.getText())

print s.substitute(d)

return s

John
