How to set pins + (I2C pins) in Micropython Portenta H7

Is there a reference card on how to address pins in Micropython ?
I also need to work with the I2C interface.
The hardware works in Arduino Standard code with the Arduiono IDE

For the I2C Interface I foud it myself:

xfreq=100000
xSCL=Pin('PH7')
xSDA=Pin('PH8')
i2c = I2C(scl=xSCL, sda=xSDA, freq=xfreq)
