One-Line List Comprehension Writing out a for loop every time you need to define some sort of list is tedious, luckily Python has a built-in way to address this problem in just one line of code. The syntax can be a little hard to wrap your head around but once you get familiar with this technique you’ll use it fairly often. Source:  Trey Hunner See the example above and below for how you would normally go about list comprehension with a for loop vs. creating your list with in one simple line with no loops necessary. x = [1,2,3,4] out = [] for item in x: out.append(item**2) print(out) [1, 4, 9, 16] # vs. x = [1,2,3,4] out = [item**2 for item in x] print(out) [1, 4, 9, 16] Lambda Functions Ever get tired of creating function after function for limited use cases? Lambda functions to the rescue! Lambda functions are used for creating small, one-time and anonymous function objects in Python. Basically, they let you create a function,  without crea...
