求教Geany中编写 ，遇到no module named“”怎么办

[qq_38609963]

class Car():
	def __init__(self,make,model,year):
		self.make=make
		self.model=model
		self.year=year
		self.odometer_reading=0
	def get_descriptive_name(self):
		long_name=str(self.year)
		return long_name.title()
	def read_odometer(self):
		print('This car has'+str(self.odometer_reading)+"miles")
		def update_odometer(self,mileage):
			if mileage>=self.odometer_reading:
				self.odometer = mileage
			else:
			   print('bu neng dong')
	def increment_odometer(self,miles):
		self.odometer_reading+=miles
from car import Car
my_ncar=('audi','A7','23')
print(my_ncar.get_description_name)
my_ncar.odometer_reading=23
my_ncar.read_odometer()

#显示no module named“car”

class Car():
	def __init__(self,make,model,year):
		self.make=make
		self.model=model
		self.year=year
		self.odometer_reading=0
	def get_descriptive_name(self):
		long_name=str(self.year)
		return long_name.title()
	def read_odometer(self):
		print('This car has'+str(self.odometer_reading)+"miles")
		def update_odometer(self,mileage):
			if mileage>=self.odometer_reading:
				self.odometer = mileage
			else:
			   print('bu neng dong')
	def increment_odometer(self,miles):
		self.odometer_reading+=miles
from car import Car
my_ncar=('audi','A7','23')
print(my_ncar.get_description_name)
my_ncar.odometer_reading=23
my_ncar.read_odometer()

这些地方的代码都有问题，第19、20行创建python对象的方式都不对。仔细看看吧

[qq_38609963]

第二十行我知道问题了 应给写成my_ncar=Car('audi','A7','）
不过十九行的from car import Car有什么问题呢

我在这里也是卡了很久，不过我看你问题细节跟我不一样，你把from car import Car以及下面的代码写在同一个表里了，你应该是新建一个表再写
