Thanks all. I usually turn strings into arrays for processing. I was
looking to see if that was the best way to do it from others that use
python. No one else uses python in my company so its nice to get
different points of view from other python users from lists like this.

Right, but CPython has array.array("c") too. Using Diez Roggisch's
code:
>>> from array import array
>>> arrs = array("c", "010203040506")
>>> arrs[:2], arrs[4:5] = arrs[4:6], arrs[:2]
>>> arrs.tostring()
'0302013040506'

That's the price to pay for immutable strings. If you have to to lots of
stuff like that, then keep things a list, and join only when you need the
result as a string.

Or, slighly slower, but more general:
def swap(s, order=(3,4,2,0,1)):
# assert len(s) >= len(order)
return ''.join([s[o] for o in order]) + s[6:]

Why not :

Hi
I was wondering if there was a nicer way to swap the first 2
characters in a string with the 4th and 5th characters other than:
darr=list("010203040506")
aarr=darr[:2]
barr=darr[4:6]
darr[:2]=barr
darr[4:6]=aarr
result="".join(darr)
The above code works fine but I was wondering if anybody had
12 matches
