... for i in range(100): ... f(i) 1. 2. 3. 4. 解释:乘法的opcode为BINARY_OP,在这个例子中我们传的是int当被特化后会变成BINARY_OP_MULTIPLY_INT,因为python弱类型,确定的类型可以极大提高速度,建议去看cpython的实现源码加深理解。 把上面代码放在.py文件中,发现无法进行特化 ...
You can do so by giving your type hint an aliased name and then using this alias as a type hint. Here’s an example of how to do this for the same function as before: Python EmailComponents=tuple[str,str]|Nonedefparse_email(email_address:str)->EmailComponents:if"@"inemail_address:us...
