回答by Martijn Pieters
file.write()only takes one argument, a string. You've given it five instead:
file.write()只接受一个参数，一个字符串。你给了它五个：
file.write("temperature is ", temperature, " wet is ", humidity, "%\n")
Make that one string:
制作一个字符串：
file.write("temperature is " + str(temperature) + " wet is " + str(humidity) + "%\n")
or use string formatting:
或使用字符串格式：
file.write("temperature is {} wet is {}%\n".format(temperature, humidity))
file.write()does notact like a printstatement.
file.write()并没有像一个print声明。
