strings are immutable and cannot be changed.  You can represent a
string as a list, change the list, and then convert back to a string.
If you need to make lots of changes, keep it as a list until you are
done and need the string back

t = '010010101001001110100101010111'
l = list(t)
l[5] = '2'
print l

# now convert back to string
tnew = ''.join(l)
print tnew
