Learn Lambda Functions by Building an Expense Tracker


I hope this is the right place.
First I’d like to thank the team for this website which is my 1st step in getting into the world of development and I appreciate all your work. I’d like to donate but you only offer me to donate monthly which is not an option for me so allowing me to donate one-time would be appreciated.

Second I’d like to say that the 1st project on Scientific Python is great, but the second with the lambda function is almost useless since I understand the menu stuff and the functions but the lambda function remains a mystery. I waited to finish the project but still nothing. You should be more clear about it… I can read more in other places but why not explain it here…?

What specifically should be explained better?

Steps 11-12 show the syntax and usage of lambda functions.
