Answer 1

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")

使其成为一个字符串：

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

或使用字符串格式：

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

file.write()是否不像一个print语句。
