我试图弄清楚我在这里继续用我的代码做错了什么。我尝试通过消除 # main 函数之后的所有内容来更改第二部分。思潮?
我收到以下错误
回溯(最近一次调用):文件 "文件",行 1、在导入宠物文件中 "文件",行 39, 在主() 文件中 "文件",行 34,在主印刷品("宠物名称:",pets.get_pet_name) 内置。UnboundLocalError:之前引用的局部变量"pets" 分配–
import petspgm
def main():
#Get a list of pet objects.
pets = make_list()
#Display the data in the list.
print('Here is the data you entered: ')
display_list(pets)
#This function gets data from the user for 3 pets. It returns a list of pet
#objects containing the data.
def make_list():
#Create an
pet_list = []
#Add three pet objects to the list
print('Enter the data for 3 pets.')
for count in range(1, 3):
#Get the pet data
print("Pet number " + str(count) + ":")
pet_name = input("Enter your pet's name: ")
pet_type = input("Enter the type of pet: ")
pet_age = float(input("Enter the pet's age: "))
#Create a new PetData object in memory and assign it to the pet variable.
pet = petspgm.PetData(pet_name, pet_type, pet_age)
#Add the object to the list.
pet_list.append(pet)
#Return the list.
return pet_list
#This function accepts a list containing PetData objects as an argument and
def pet_list():
#displays the data stored in each object.
display_list(pet_list)
for item in pet_list:
print("Pet's name is: " + item.get_pet_name())
print("Pet's type is : " + item.get_pet_type())
print("Pet's age is : " + item.get_pet__age())
#Call the main function
main()
这是代码的另一半:
class PetData(object):
def __init__(self, name, animal_type, age):
self.__pet_name = pet_name
self.__pet_type = pet_type
self.__pet_age = pet_age
def set_name(self, name):
self.__pet_name = pet_name
def set_type(self, animal_type):
self.__pet_type = pet_type
def set_age(self, age):
self.__pet_age = pet_age
def get_name(self):
return self.__pet_name
def get_animal_type(self):
return self.__pet_type
def get_age(self):
return self.__pet_age
# The main function
def main():
# Prompt user to enter name, type, and age of pet
name = input('What is the name of the pet: ')
animal_type = input('What type of pet is it: ')
age = int(input('How old is your pet: '))
print('This will be added to the records. ')
print('Here is the data you entered:')
print('Pet Name: ', pets.get_pet_name)
print('Animal Type: ', pets.get_pet_type)
print('Age: ', pets.get_pet_age)
pets = Pet(name, animal_type, age)
main()
在主要:
print('This will be added to the records. ')
print('Here is the data you entered:')
print('Pet Name: ', pets.get_pet_name)
print('Animal Type: ', pets.get_pet_type)
print('Age: ', pets.get_pet_age)
pets = Pet(name, animal_type, age)
在实际初始化/声明之前打印宠物值。我想你想要:
pets = Pet(name, animal_type, age)
print('This will be added to the records. ')
print('Here is the data you entered:')
print('Pet Name: ', pets.get_pet_name)
print('Animal Type: ', pets.get_pet_type)
print('Age: ', pets.get_pet_age)
