回答1:

file.write() only takes one argument, a string. You've given it five instead:

file.write("temperature is ", temperature, " wet is ", humidity, "%\n")

Make that one string:

file.write("temperature is " + str(temperature) + " wet is " + str(humidity) + "%\n")

or use string formatting:

file.write("temperature is {} wet is {}%\n".format(temperature, humidity))

file.write() does not act like a print statement.
