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

In Python >= 3.6, the new f-string is an efficient way to concatenate a string.

>>> name = 'some_name'
>>> number = 123
>>>
>>> f'Name is {name} and the number is {number}.'
'Name is some_name and the number is 123.'
