Why no string return?

gargonx

Say i have the two methods:

def ReturnMethod(request, x):
if request is True:
return x
else: print "No String for you...False!"

def SendMethod(request):
xstring = "Some text"
ReturnMethod(request, xstring)

SendMethod(True)

Why does ReturnMethod not return the string x? I do believe it is
returning with a NoneType.
Any help would be greatly obliged

Thanks, Josh

That is because request is bound a string (str) object. You are probably
testing for null so it should look like:

if request:
return x
else:
print "No String for you...False!"

Hope this helps.

Still no return of string. The null testing is not really the deal.
that could be replaced with anything EG:

def ReturnMethod(request, x):
if request is 'random':
return x
else: print "No String for you...False!"

def SendMethod(request):
xstring = "Some text"
ReturnMethod(request, xstring)

SendMethod('random')

ReturnMethod() is executed, but you do nothing with the result.

Try one of the following -

def SendMethod(request):
xstring = "Some text"
print ReturnMethod(request, xstring)

def SendMethod(request):
xstring = "Some text"
return ReturnMethod(request, xstring)

You shouldn't test with `is' but with `=='.
