How to change an element of a string?

[ilSignorCarlo]

Hi,

in an application I'm developing I need to change some elements in a string. It contains just 1 and 0, and I need to change, sometimes, a particular 1 to 0 or viceversa.

Is there any simple method to do this?

Thanks,
Carlo

There are a couple of ways you can approach this.

>>> s = '100111010100011'
>>> s1 = s.replace('111', '101')
>>> s1
'100101010100011'
>>> s2 = s1[:4]+'1'+s1[5:]
>>> s2
'100111010100011'
>>> 

The string replace() method and slicing. The string itself is immutable, so these methods return a new string.

Mmm, maybe I can use the slicing to change just one element.

Yep. Like lines 5 thru 7 above do...
