This is the code:
OK, But it's not clear from that why you want the type.
You are not doing anything meaningful with the type.
class Tag:
def __init__(self, nom, tipus, valor):
self.nom = nom
self.tipus = tipus
self.valor = valor
def __str__(self):
return "Nom: " + str(self.nom) + ", Tipus: " + str(self.tipus) + ",
Valor: " + str(self.valor)
You store it then print the string version of it.
Why not just pass a string name?
def main():
a = Tag("descripció", str, "primera tasca")
b = Tag("unmes", str, lambda x: x+1)
c = Tag("twice", type(lambda: x: x), lambda x: 2*x)
and it fails here:
$ python3 tasques.py
File "tasques.py", line 26
c = Tag("twice", type(lambda: x: x), lambda x: 2*x)
^
SyntaxError: invalid syntax
As it says there is a syntax error. Look at your two lambda
expressions, the second one has an extra :
Thanks a lot,
It works with
c = Tag("twice", type(lambda x: x), lambda x: 2*x)
but I want to specify the type of (lambda x: x) **manually** as I do
with str in b
Thanks
