Python Lambda Functions: Summary

Now that you’ve completed this step-by-step course, you know how to use Python lambda functions! You are now able to do all of the following:

  • Write Python lambdas and use anonymous functions
  • Choose wisely between lambdas or normal Python functions
  • Avoid excessive use of lambdas
  • Use lambdas with higher-order functions or Python key functions

Python lambdas are like salt. A pinch in your spam, ham, and eggs will enhance the flavors, but too much will spoil the dish. If you have a penchant for mathematics, you may have some fun exploring the fascinating world of lambda calculus.

Wonderful! This provided so much clarity to lambda. I haven’t used it much but will start now since I know how it works. Thanks.

This is a great idea to combine sort/map/filer/reduce with the lambda explanation! Finally I understand the concept and power of a lambda function. Thank you.
