reads as follows:1receive: Hello2receive: World 3currentThe method is the necessary method for the iterator ( Iterator ) interface, where each iteration of the foreach statement obtains the current value and then invokes the iterator's next method. We call the current method to get the value manually in order for the program not to execute indefinitely.The above example is enough to indicate that the yield is in that position as two-way transmission 工具 , and the conditions for the implementatio

Overview
The Golang is a lightweight thread in the perfectly formed, while the Golang management process is bound to involve the transition between the threads: the blocking process is switched out, and the running coprocessor is switched in. In this section, we will carefully analyze how the process is switched.
Tls
Thread Local Storage:
GETG ()
GoGet () is used to get the current thread being executed by the proc
Co-process
is a user-configured link thread micro-threading
Benefits
No overhead for thread context switching
No need for atomic operation locking and synchronization overhead
Simplified programming model for easy switching control
High concurrency + high scalability + low cost
Disadvantages
The inability to take advantage of multi-core resources is essentially a single thread that does not need to use multicore to combine multiple processes to take

Basement Renovation Sewage TreatmentIn most people's impressions the basement is probably dark, damp, shabby and messy. This is also the basement of the current embarrassment, in fact, there is a lack of a multi-stakeholder to benefit from the solution. To do is to explore a sustainable, replicable model of basement development, building the basement into a vibrant underground community that attracts more people to the ground. At present, Henan step Xinyuan Decoration Engineering

The existence of the Gil Lock makes it possible for Python to achieve multi-threaded parallelism through multicore, and if you want Python to take advantage of multicore, it can only be done by opening multiple processes. So Python is suitable for computationally intensive tasks.Resource preemption: threads, processesCo-operation: Cooperative----> Non-preemptive program, Keywords: yield generator, the main solution is also IO operations, but can not take advantage of multi-core (no multi-process
1. Co-process (micro-threading)A process is a lightweight thread that is user-state.The co-process has its own register context and stack. When the schedule is switched, the register context and stack are saved elsewhere, and the previously saved register context and stack are restored when it is cut back. So:The process can retain the state of the last invocation (that is, a specific combination of all loc
