You can "update" an existing string by (re)assigning a variable to another string. The new value can be related to its previous value or to a completely different string altogether. For example −
Example
#!/usr/bin/python var1 = 'Hello World!' print "Updated String :- ", var1[:6] + 'Python'
Output
When the above code is executed, it produces the following result −
Updated String :- Hello Python
