Pull Request Report

@jenia90 Hello! I'm a bot made to check all the pull request Python files. First of all, I want to say thank you for your time and interest in this project and for opening a pull request. There seems to be missing requirements in some of the Python files submitted in this pull request. Please read through the report and make the necessary changes. You can take a look at the relevant links provided after the report.

What are node paths? 🔽

The report contains headings and a checklist where the items are paths to the class/function/parameter where the requirement is missing. Node paths are double colon :: separated names and can be in any of the following format:

• Class path: [file_name]::[class_name]
• Function path: [file_name]::[function_name]
• Function parameter path: [file_name]::[function_name]::[parameter_name]
• Method path: [file_name]::[class_name]::[function_name]
• Method parameter path: [file_name]::[class_name]::[function_name]::[parameter_name]

Following class/functions/parameters require descriptive names:

• blockchain/chinese_remainder_theorem.py::extended_euclid::a
• blockchain/chinese_remainder_theorem.py::extended_euclid::b
• blockchain/chinese_remainder_theorem.py::invert_modulo::a
