Foreword
I have been on my work for a while, like about two months. When I was in university I mainly wrote code with Python, but now I have to get familiar with C++ as soon as possible - almost all backend engineering codes are written in C++.
However, Python is a great tool for fast development. If I would like to write a simulator or information generator, Python is still my first choice. Last week when I wrote a position information generator for containers, I have met several traps and finally overcome them. Here is a brief summary.
Problem Description
- When saving data in the style of json, it can not be deserialized in the right format in C++;
- When appending a dict object in a list in python, all elements in the list will be changed at the same time.
Solution
For the first problem, users can specify the json style with parameters in Python. The details can be checked here.
For the second problem, it is because I directly push the object into the list. Actually it is a pointer to the object. The details can be checked here. Just use copy.deepcopy() to solve the problem.
Summary
This is a short article since I didn’t have enough time to record a simple proble in detail. But wrting down is always better than memory, as a Chinese old saying presents.
