Which is the preferred way to concatenate a string in Python?

Question

Since Python\'s string can\'t be changed, I was wondering how to concatenate a string more efficiently?

I can write like it:

s += string         


        

Answer 1

You write this function

def str_join(*args):
    return ''.join(map(str, args))

Then you can call simply wherever you want

str_join('Pine')  # Returns : Pine
str_join('Pine', 'apple')  # Returns : Pineapple
str_join('Pine', 'apple', 3)  # Returns : Pineapple3
