LCD-16398 20x4 SerLCD with Pro Micro RP2040

This display is working very nicely on my Pi400 using one of the examples. However, I also want it to work with an RP2040 Pro Micro, also with Thonny. Trying the “Hello World” example I get "ImportError: no module named ‘future’ from line 1 which is “from future import print_function”. I imported “sparkfun_qwiic_serlcd”, but there must be something I missed.

What is the significance of the underscore symbols before and after the word future. First time I’ve seen this in MicroPython.
