Let's say we have a text "Welcome to India". And I want to multiply this string with 3, but to appear with comma delimitation, like "Welcome to India, Welcome to India, Welcome to India". The thing is I know this piece of code could work:

a = 'Welcome to India'

required = a * 3 # but this code is not comma-delimited.

Also, this piece of code doesn't work as well

required = (a + ", ") * 3 # because it puts comma even at the end of the string

How to solve this problem?

Based on the part of your code that you say doesn't work well because it adds a comma to the end, you can modify it like this:

required = (a + ", ") * 2 + a

Or if you don't like it, you can use sum instead of multiply, it's not the optimal way, for sure, but it will work:

a = 'Welcome to India'
required = a + ", " + a + ", " + a

Define Function and you can use it.

def commaFunc(value, count):
    buffer = []
    for x in range(count):
        buffer[x] = value
    return ",".join(buffer)
