Perhaps it's time for a new thread.
If you are using I2C with a char lcd, I am assuming you're talking about driving it with a PCF8574 or a MCP23008/MCP23017 backpack.
https://github.com/dhylands/python_lcd has examples using both, and also plain old 4 or 8bit GPIO.
The ESP8266 examples are compatible with the PCF8574, if you change the pins in the I2C() construct, like you have in your example above.
