Sort a string in lexicographic order python

Question

I would like to sort a string into a list in the lexicographic order as

str='aAaBbcCdE'

to

['A','a','a','B','b','C','c','d','E']

But when I use sorted(), it gives me

['A','B','C','E','a','a','b','c','d']

Can anyone tell me, How can I get the output in lexicographically?

Answer 1

Try not to utilize lambda functions when there are built-in ones for the work. Additionally, never utilize the cmp arguments of sorted, the reason is that it's deplored:

sorted(s, key=str.lower)

or

sorted(s, key=str.upper)

But, that won't keep "A" & "a" in order, so:

sorted(sorted(s), key=str.upper)

that will and, by the idea of sorted the activity will be extremely quick for nearly sorted list (the second arranged).
