以下是一个示例,演示了如何使用json模块将类转换为JSON字符串: importjsonclassBook:def__init__(self,title,author):self.title=title self.author=author book=Book("Python for Beginners","John Smith")json_string=json.dumps(book.__dict__)print(json_string) 1. 2. 3. 4. 5. 6. 7. 8. 9. ...
定义 str()将对象转换为适合阅读的字符串形式。 语法 classstr(object='') 参数 object -- 对象。 返回值 返回一个对象的string格式。 实例 1s ='RUNOOB'2print(str(s))#输出RUNOOB3dict = {'runoob':'runoob.com','google':'google.com'}#输出{'runoob': 'runoob.com', 'google': 'google.com'}...
在Python中,还可以使用repr()函数将其他数据类型转换为String类型。repr()函数返回一个对象的字符串表示形式,该字符串可以用来重新创建该对象。下面是一个示例: num=10str_num=repr(num)print(str_num)# 输出: '10'print(type(str_num))# 输出: <class 'str'>bool_val=Truestr_bool=repr(bool_val)print(...
classPerson:def__init__(self,name,age):self.name=name self.age=agedef__str__(self):returnf"Person(name={self.name}, age={self.age})"person=Person("Alice",25)string_representation=str(person)print(string_representation) 运行以上代码,输出结果如下: 代码语言:txt 复制 Person(name=Alice, ag...
When you compute a value in the REPL, Python calls __repr__ to convert it into a string. When you use print, however, Python calls __str__. When you call print((Item("Car"),)), you're calling the __str__ method of the tuple class, which is the same as its __repr__ meth...
<class 'bytes'> Output: GeeksForGeeks <class 'str'> 方法#3:使用 codecs.decode() 方法 此方法用于将二进制字符串解码为正常形式。 Python3 # Program for converting bytes to string using decode()# import required moduleimportcodecs data =b'GeeksForGeeks'# display inputprint('\nInput:') ...
string_object = 'Hello, world!' bytes_object = string_object.encode('utf-8') print(bytes_object) # 输出: b'Hello, world!' print(type(bytes_object)) # 输出: <class 'bytes'> ``` 在这个示例中,我们将一个字节对象转换为字符串对象,然后将字符串对象转换回字节对象。
