Write a parser with the data in the file

You need to parse the data from 1 service through the API, and from 3 sites. In total, you need to pair about 18 variables for the program (their number may change during the writing of the program, but slightly). 13 variables from the service through the API. The remaining 3 variables from 3 different sites. Parser should collect data, conduct simple operations with them, and conveniently bring it to the file for further work with them.

Ill put you on video, where to take what variables to take, and you should study the API of the first service. Ill give him access to get to know him. From the sites what data to pars - I also write a video, there everything is simple.

In general, a more detailed analysis I hope to spend through the calls to show through the teamviewer what to get from.
