A 'str' object is immutable, which means simply that you cannot modify
it in place. All you can do is create a new str object, and rebind your
variable to that new one. That means that there are a number of things
you cannot do directly to a string. One of them is modifying a slice,
as you're trying to do.
datecode = "201504110102030405061"
print datecode
if datecode[20:21] == "1":
datecode[20:21] = "0"
print datecode
I can see that the first part of this is probably a standard datetime,
and might suggest you convert it to one, and modify that as needed. But
you're so far to the right that I have to figure you're doing some
custom encoding.
If you just want to replace a single character of a string, you could
use the construct:
datecode = datecode[:20] + "0" + datecode[21:]
If you need something fancier, perhaps you can generalize it.
