在Python中,你可以定义一个名为`Book`的类,如下所示:
```python
class Book:
def __init__(self, name, author, isbn, publisher, price):
self.name = name
self.author = author
self.isbn = isbn
self.publisher = publisher
self.price = price
# 定义info()方法来获取书籍信息
def info(self):
return f"书名: {self.name}\n作者: {self.author}\nISBN: {self.isbn}\n出版社: {self.publisher}\n价格: {self.price}"
# 创建一个实例并打印其信息
my_book = Book("Python编程入门", "John Doe", "978-1234567890", "O'Reilly", 50.99)
print(my_book.info())
```
当你创建一个`Book`类的实例并调用`info()`方法时,它会返回包含所有属性值的信息。

定义一个Book类,属性:name、author、isbn、publisher和price,方法:info(),输出name、author、isbn、publisher、price
好的,以下是定义一个Book类的Python代码,满足您的要求:
```python
class Book:
def __init__(self, name, author, isbn, publisher, price):
self.name = name
self.author = author
self.isbn = isbn
self.publisher = publisher
self.price = price
def info(self):
print(f"Name: {self.name}\nAuthor: {self.author}\nISBN: {self.isbn}\nPublisher: {self.publisher}\nPrice: {self.price}")
```
其中,`__init__`方法用于初始化类的属性,`info`方法用于输出书籍信息。可以使用以下代码创建一个Book对象并输出信息:
```python
book = Book("Python for Data Science Handbook", "Jake VanderPlas", "9781491912058", "O'Reilly Media", 39.99)
book.info()
```
输出结果为:
```
Name: Python for Data Science Handbook
Author: Jake VanderPlas
ISBN: 9781491912058
Publisher: O'Reilly Media
Price: 39.99
```
py请定义一个Book类,属性:name、author、isbn、publisher、和price,方法info(),输出name、author、isbn、publisher和price
好的,以下是定义一个Book类并实现其属性和方法的 Python 代码:
```python
class Book:
def __init__(self, name, author, isbn, publisher, price):
self.name = name
self.author = author
self.isbn = isbn
self.publisher = publisher
self.price = price
def info(self):
print(f"Name: {self.name}\nAuthor: {self.author}\nISBN: {self.isbn}\nPublisher: {self.publisher}\nPrice: {self.price}")
```
你可以使用上述代码来创建一个名为“book”的Book对象,然后调用info()方法将其属性输出到控制台:
```python
book = Book("Python for Dummies", "John Smith", "1234567890", "Wiley", 29.99)
book.info()
```
输出将会是这样的:
```
Name: Python for Dummies
Author: John Smith
ISBN: 1234567890
Publisher: Wiley
Price: 29.99
```
