Is it possible to write code and allow a function to be called within another like I have shown below ?
Pete
def populatelist():
f=open(_globals.appath + "dxcluster.svr","r")
while true:
text = f.readline()
if text =="":
break
_list.append(string.strip(text)) f.close()
def serversettings():
servers.main(root)
if _globals.refresh=="yes":
populatelist() <----------------------- calling function above.
Yes. It is perfectly normal. As programs get more complex, you find methods calling methods calling methods. And as Kent pointed out, you are already callin methods from withon methods by calling the likes of open() and close().
Beware of creating loops - methods that call themselves, eitehr directly or by calling other methods that end up calling the original method. This can be done with care to make sure that at some point a method is sure to return without calling onwards, usually by having the problem simplified every time, but you should avoid this kind of thing for now. It's called recursion. An example would be in calculating x to the power of y. x^y can be calculated by working out x * x^(y-1), but x^(y-1) is x * x^(y-2) etc. But you canbe sure this ends when we finally come to work out x^1 which is x, and this breaks the loop. If that makes sense.
