While we seem to be playing code golf... `x,y = map(float, re.findall('\d+\.\d+', s))` – Cory Kramer Aug 19 '15 at 18:39

`a,b = map(float, s.strip("[]").split(","))` – Padraic Cunningham Aug 19 '15 at 18:41

d = [float(e) for e in ("[12.45,56.78]")[1:-1].split(",")] – dsgdfg Aug 19 '15 at 18:43

or
x = "[12.45,56.78]"
myList= eval(x)
myList[0]
Out[1]: 12.45
myList[1]
Out[2]: 56.78

You can use ast.literal_eval() to evaluate the string and convert to list and then unpack them into two variables. Example -
>>> import ast
>>> a,b = ast.literal_eval("[12.45,56.78]")
>>> a
12.45
>>> b
56.78
