i have basic question. reason i'm not able recall how it. how access variables defined in function not declared in class. how access y variable ? , how pass value lambda ? , how value of c defined inside lambda ?

    def fun ():         y = 100         x = lambda c,s,y : c*s*y 

also how pass values lambda function ?

if want use y in lambda don't specify argument lambda:

def fun():     y = 5     x = lambda c, s: c*s*y     return x(2, 3)  >>> fun() 30
