C++ has been my primary language in my entire career until a year ago, when Python came to our tool set.
We chose Python for it’s rich collection of modules. In our case, for example:

1. AI: keras module to TensorFlow for player recognition
2. REST API: bottle and json module, through which AWS server talks to the clients
3. Database: pymysql module access video recordings saved in MySql
4. HLS Playlist parsing: m3u8 module
5. Access AWS: boto3 module to control ec2 instances
