Python Processes and Threads

process:    Advantages: Simultaneous use of multiple CPUs to enable colleagues to perform multiple operations    disadvantages: Consuming resources (re-opening up memory space) Threads:    Advantages: Shared memory, IO operation time, create concurrency Operation    Disadvantage: preemption resource processes and threads are not the more the better    process: Number of CPUs = number of processes    thread: Request context switch time-consuming

The smallest unit of execution of a task in a computer is: thread
IO operation without CPU
IO-intensive:
Multithreading
Compute Intensive:
Multi-process
Python exclusive Gil (Global interpreter Lock)
