How do I efficiently convert list items into strings for joining in Python?

Converting List Items to Strings for Joining

To join a list of items efficiently, they must all be strings. However, if some items in your list are integers from function calls, you'll need to convert them to strings.

Pythonic Conversion Method

The Pythonic way to convert an object to a string is using the str(...) function:

myList.append(str(myfunc()))

This method converts the returned integer from myfunc() into a string.

Alternative Approach

You could also temporarily store the integers in separate variables and then convert them to strings. However, this approach is less efficient than using str(...) directly.

temp_value = myfunc()
myList.append(str(temp_value))

List Customization

Consider keeping your list as integers until necessary for display. This prevents unnecessary conversions. For example, to print the list with commas:

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

This method dynamically converts each integer to a string within the join operation, maintaining efficiency and the desired output.
