I have two lists.
a = ["P", "h", "o", "n", "e"]
b = ["P", "n", "o", "e", "h"]
How do I sort b to be like a?

their lengths always same? – salmanwahed Jun 26 '16 at 09:35

`sorted(b, key=lambda element: a.index(element))`? But this will be tricky if you have duplicate elements. – jonrsharpe Jun 26 '16 at 09:36

@jonrsharpe: or `sorted(b, key=a.index)` – zondo Jun 26 '16 at 09:36

@zondo oh nice one, yes. Same problem, though. Frankly `b = a[:]` is the easiest solution. – jonrsharpe Jun 26 '16 at 09:36

3What do you mean "sort `b` to be like `a`"? If you already have `a`, make a copy of it? – thefourtheye Jun 26 '16 at 09:37

4What if `b` is `["P", "n", "o", "k", "l", "h"]`? How would it be sorted? – zondo Jun 26 '16 at 09:38

@zondo Yup. That did that trick. Thanks a bunch! – Light Jun 26 '16 at 10:24

@thefourtheye I'm building a Hangman game. To display the progress the player was making I had to show him the letters he guessed in order. That's why I needed to sort the second list like the first. – Light Jun 26 '16 at 10:49
