C++ or Python, which one is more suitable for beginners?

To create a Python virtual environment, you can use the venv module. The steps are: 1. Enter the project directory to execute the python-mvenvenv environment to create the environment; 2. Use sourceenv/bin/activate to Mac/Linux and env\Scripts\activate to Windows; 3. Use the pipinstall installation package, pipfreeze>requirements.txt to export dependencies; 4. Be careful to avoid submitting the virtual environment to Git, and confirm that it is in the correct environment during installation. Virtual environments can isolate project dependencies to prevent conflicts, especially suitable for multi-project development, and editors such as PyCharm or VSCode are also

Use the Pythonschedule library to easily implement timing tasks. First, install the library through pipinstallschedule, then import the schedule and time modules, define the functions that need to be executed regularly, then use schedule.every() to set the time interval and bind the task function. Finally, call schedule.run_pending() and time.sleep(1) in a while loop to continuously run the task; for example, if you execute a task every 10 seconds, you can write it as schedule.every(10).seconds.do(job), which supports scheduling by minutes, hours, days, weeks, etc., and you can also specify specific tasks.

If it is iterating when deleting an element, you must avoid using a failed iterator. ①The correct way is to use it=vec.erase(it), and use the valid iterator returned by erase to continue traversing; ② The recommended "erase-remove" idiom for batch deletion: vec.erase(std::remove_if(vec.begin(),vec.end(), condition), vec.end()), which is safe and efficient; ③ You can use a reverse iterator to delete from back to front, the logic is clear, but you need to pay attention to the condition direction. Conclusion: Always update the iterator with the erase return value, prohibiting operations on the failed iterator, otherwise undefined behavior will result.

TagDispatching uses type tags to select the optimal function overload during the compilation period to achieve efficient polymorphism. 1. Use std::iterator_traits to obtain the iterator category tag; 2. Define multiple do_advance overload functions, and process random_access_iterator_tag, bidrectional_iterator_tag and input_iterator_tag respectively; 3. The main function my_advance calls the corresponding version based on the derived tag type to ensure that there is no runtime overhead during the compile period decision; 4. This technology is adopted by standard libraries such as std::advance, and supports extended customization.
