How to enter I2C address in seeed-ardupy-bme280?

The example on the web page ( …

from arduino import grove_bme280
import time
bme280 = grove_bme280()
while True:
print ("Temperature: ", bme280.temperature, “C”)
print ("Humidity: ", bme280.humidity, “%”)
print ("Pressure: ", bme280.pressure, “Pa”)

doesn’t say which I2C address to use but the example still works. How is this possible?

The I2C address is already included in the driver and the user only needs to get the sensor information.
