Insert some string into given string at given index in Python


I am newbie in Python facing a problem: How to insert some fields in already existing string?

For example, suppose I have read one line from any file which contains:

line = "Name Age Group Class Profession"

Now I have to insert 3rd Field(Group) 3 times more in the same line before Class field. It means the output line should be:

output_line = "Name Age Group Group Group Group Class Profession"

I can retrieve 3rd field easily (using split method), but please let me know the easiest way of inserting into the string?

An important point that often bites new Python programmers but the other posters haven't made explicit is that strings in Python are immutable -- you can't ever modify them in place.

You need to retrain yourself when working with strings in Python so that instead of thinking, "How can I modify this string?" instead you're thinking "how can I create a new string that has some pieces from this one I've already gotten?"
