python - Struggling with slice syntax to join list element of a part of a list -

suppose have simple python list this:

>>> l=['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'] 

now suppose want combine l[2:6] single element this:

>>> l ['0', '1', '2345', '6', '7', '8', '9'] 

i able in steps new list, this:

>>> l2=l[0:2] >>> l2.append(''.join(l[2:6])) >>> l2.extend(l[6:]) >>> l2 ['0', '1', '2345', '6', '7', '8', '9'] 

is there way (that missing) more , in place on original list l?

edit

as usual, sven marnach had perfect instant answer:

l[2:6] = ["".join(l[2:6])] 

i had tried:

l[2:6] = "".join(l[2:6]) 

but without braces, string produced join treated iterable placing each character in list , reversing join!

consider:

>>> l=['abc','def','ghk','lmn','opq'] >>> l[1:3]=[''.join(l[1:3])]  >>> l ['abc', 'defghk', 'lmn', 'opq']   #correct  >>> l=['abc','def','ghk','lmn','opq'] >>> l[1:3]=''.join(l[1:3]) >>> l ['abc', 'd', 'e', 'f', 'g', 'h', 'k', 'lmn', 'opq']   #not correct 

use slice assignment:

l[2:6] = ["".join(l[2:6])]
