str' object does not support item assignment

Problem:

I am working on python string.

import string
import re
str = "Hello"
b = 0
srr = ""
for a in str:
    srr[b] = a #'str' object does not support item assignment 
    b = b + 1
print (srr)

This is my sample code. I was trying to read some characters from a string and put it into another string like C or Java but it’s not working for my case.
Thanks. I must recognize your help.

Solution:

Strings are immutable in Python. You can not change the characters in their place. But you are allowed to do

for a in str:
    srr += a

This program creates a new String with each iteration and stores a new String in srr.
