在你的 Python 代码中,你可以导入生成的example_pb2模块,并使用ParseFromString方法解析字节流。 importexample_pb2# 假设 bytes_data 是一个有效的 Protobuf 字节流bytes_data=b'\x0a\x03Bob\x10\x01\x1a\x0b\x62ob@example.com'# 创建一个 Person 对象person=example_pb2.Person()# 解析字节流person....
>>>parse("I am {:d}","I am 27")<Result (27,) {}>>>type(_[0])<type 'int'>>> 其等价于 >>>defmyint(string):...returnint(string)...>>>parse("I am {:myint}","I am 27",dict(myint=myint))<Result (27,) {}>>>type(_[0])<type 'int'>>> 利用它,我们可以定制很多的...

l = [1, 2, 'hello', 'world'] # 列表中同时含有int和string类型的元素 l [1, 2, 'hello', 'world'] tup = ('jason', 22) # 元组中同时含有int和string类型的元素 tup ('jason', 22) 其次,我们必须掌握它们的区别。 列表是动态的,长度大小不固定,可以随意地增加、删减或者改变元素(mutable)。

int()is very limited when it comes to expressions it can parse. If it receives an input string that cannot be converted to an integer due to an incompatible form, it will raise aValueErrorexception. Therefore, it's recommended to use a validation method ortry-catchblock when usingint()for...
