@sandraUsf please recheck the spacing, 1.before def (there should be only 2 spaces)
2. The documentation they should be on the same line and only 2 spaces ahead like def, along with they should be all on the same row :)
3. there should be one space line separating between Documentation and the method
4. as youm mentioned " take_number_of_years and list_startups aren't mentioned in the class diagram, please tell you team leader to make an issue to the class diagram owner for them to be added ASAP"
5. the method name should be in a form of snake case :) recheck the implementation reviews @yomn-el-mistikawy has sent
