Hi all, I would like to ask you how I can use the more efficient join
operation in a code like this:
class Test:
... def __init__(self, v1, v2):

Hi all, I would like to ask you how I can use the more efficient join
operation in a code like this:
class Test:
... def __init__(self, v1, v2):
... self.v1 = v1
... self.v2 = v2
...
def prg(l):
... txt = ""
... for x in l:

You can just append each string to a list and call "".join(list) on the
list. Here is a mock-up StringBuilder class:
class StringBuilder:
def __init__(self): self.strlis
