我已经创建了一个python类,我希望能够通过运行import car
来使用它,我相信它是正确的语言。目前,我可以在我的类中使用任何东西的唯一方法是在python3 IDE单击运行中打开文件(/home/pi/Desktop/python/car.py
),然后使用我的类。
我相信/usr/lib/python3.4
将是适当的地方,但我已经尝试过了,输出就在这里:
>>> import car
>>> my_car = car('n', 'vns', '15', '13')
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
my_car = car('n', 'vns', '15', '13')
TypeError: 'module' object is not callable
类代码可能是不必要的,但在这里:
class car():
"""Your car."""
def __init__(self, make, model, year, fuel_capacity):
"""Atributtes of your car, fuel in gallons."""
self.make = make
self.model = model
self.year = year
self.fuel_capacity = fuel_capacity
self.fuel_level = 0
def fill_tank(self):
"""Fill up your gas."""
self.fuel_level = self.fuel_capacity
print("Fuel tank is full")
def drive(self):
"""Drive your car"""
print("The car is moving")
self.fuel_level = self.fuel_level
def specs(self):
print(self.year, self.make, self.model, self.fuel_capacity, "Gallons")

首先,不要在Python安装目录中创建本地模块。
由于您未指定PYTHONPATH
,因此无法导入模块。
您应该在命令行中导出该模块的路径。
export PYTHONPATH=/home/pi/Desktop/python/
此外,根据PEP8,类名应使用CapWords约定。见https://www.python.org/dev/peps/pep-0008/#id39
现在进入你的python交互式shell,你应该能够导入该模块。
from car import Car

import car
my_car = car('n', 'vns', '15', '13')
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
my_car = car('n', 'vns', '15', '13')
TypeError: 'module' object is not callable
你在一般的python开发中犯了一些错误,但回答你的问题,为什么它现在不能正常工作:
car.car('n', 'vns', '15', '13')
代替car
