hi all
i want to check a condition and if true should return a filename
string from a list.if the condition is false i am returning a
"" (string literal)..
retv=""
if somecondition:
retv=mylist[x]
...
return retv
The calling function will check the return value and print the
filename if it is not """.
in the calling function i can code
if returnval !="":
print "filename is:",returnval
else:
print "no filename found"
what i want to know is ,should i rewrite the if returnval !="" as
if returnval:
print "filename is:",returnval
else:
print "no filename found"
or is the way i coded the right way ? i am little confused here
Someone suggested that i make a variable retv None and if the
condition true then set retv as filename ,
retv=None
if somecondition:
retv=mylist[x]
...
return retv
which approach is correct..? can someone help please
vincent
