No support for sort keys?

[danieltanfh95]

a=["a","aa"]
a.sort(key=len)
print(a)

This returns an error that key is not a defined keyword argument:
SyntaxError: Unexpected token
TypeError: Cannot read property 'type' of undefined

This is not supported yet.

#26 is tracking adding the sort method to lists
#8 is tracking adding keyword arguments

Here is a workaround:

def cmp(a, b): return len(a) - len(b)
a=["ccc", "a","aa"]
a = sorted(a, cmp)
print(a)

Thanks for the feedback!

I just wanted to make a comment regarding your workaround...

cmp is for comparisons of two items. in this case, a and b.

if cmp returns a negative, that means a is less than b.
if it returns zero, they are equal, and if it returns a positive value, greater than

so differentmatt, your code is wrong. here's what it should be:

def cmp(a, b): return len(a) - len(b)
a=["ccc", "a","aa"]
a = sorted(a, cmp)
print(a)

Good catch, updated comment.
