Help Interpreter. To all of the Master Of Coding Here

for example this is a help of a command in python i need to understand well how to read this and implement it in a real Case

for example when said  StreamReader(stream: Stream)  or StreamReader(path: str) 

what exactly i need to write between the Parenthesis?

or when something appears with tow __new__
