The Gil is not a Python feature, it is a concept introduced when implementing the Python parser (CPython). Just like C + + is a set of language (syntax) standards, but can be compiled into executable code with different compilers. Well-known compilers such as Gcc,intel c++,

saysHy's Eval is the first to be compiled into Python's AST. (similar to the GCC front-end language compiled to RTL AST)But "although you can put abstract objects into hyexpression, but can't compile it"On the one hand Hy's compiler only accept Hymodel (hyexpression hylist hysymbol There are basic types Hyint hystring and so on),On the other hand: in the Python ast, function object does not have an explicit representation, so there is no corresponding Hymodel (the same goes for other custom p

Perhaps before joining the continuation, it is important to talk about the cost of doing it so much. After all, the results are the same with no continuation calculation. However, this is a series of interests, learning this knowledge should be entirely out of curiosity and fun ideas. That's why I'm not going to tell you. Through control continuation can achieve call-with-current-continuation and exception handling functions.
Let me briefly describe how the
LAMDBA is actually an anonymous function.The lambda syntax for defining Lisp is very simple, as follows:(Lambda ([parameter]) [Experssion])There are three ways to invoke the lambda syntax, as follows:First type: ((lambda (x) (+ x 1)) 100); Add parameters directly to the backThe second type: (Apply # ' (Lambda (x) (+ x 1)) ' (100)); Use the Apply function to pass in a list table in the last argumentThe third type: (Funcall # ' (Lambda (x) (+ x 1) 100))

In Windows, the python 2.x interpreter and the 3.x interpreter coexist.
Python2 and Python3 are incompatible. If you encounter a situation where you cannot upgrade to Python2 code or your colleagues stick to the Python2 camp, you must consider the coexistence of Python2 and Python3 in the system.
Mac OS X and Linux do not have to consider this situation. Because these Unix-like operating systems will dire
