python string list

I need to join a list of items. Many of the items in the list are integer values returned from a function; i.e.,

myList.append(munfunc())

How should I convert the returned result to a string in order to join it with the list?

Do I need to do the following for every integer value:

myList.append(str(myfunc()))

Is there a more Pythonic way to solve casting problems?

Calling str(...) is the Pythonic way to convert something to a string.

You might want to consider why you want a list of strings. You could instead keep it as a list of integers and only convert the integers to strings when you need to display them. For example, if you have a list of integers then you can convert them one by one in a for-loop and join them with ,:

print(','.join(str(x) for x in list_of_ints))
