Small Python optional arguments question
- by ooboo
I have two functions:
def f(a,b,c=g(b)):
blabla
def g(n):
blabla
c is an optional argument in function f. If the user does not specify its value, the program should compute g(b) and that would be the value of c. But the code does not compile - it says name 'b' is not defined. How to fix that?
Someone suggested:
def g(b):
blabla
def f(a,b,c=None):
if c is None:
c = g(b)
blabla
But this doesn't work, because maybe the user intended c to be None and then c will have another value.
