Can I sort text by its numeric value in Python?

Question

I have dict in Python with keys of the following form:

mydict = {\'0\'     : 10,
          \'1\'     : 23,
          \'2.0\'   : 321,
          \'2.1\'   : 3         


        

Answer 1

As an addendum to Ian Clelland's answer, the map() call can be replaced with a list comprehension... if you prefer that style. It may also be more efficient (though negligibly in this case I suspect).

sorted(mydict.keys(), key=lambda a: [int(i) for i in a.split('.')])
