Fibonacci using list comprehension python
WebStarting in Python 3.8, and the introduction of assignment expressions (PEP 572) ( := operator), we can use and increment a variable within a list comprehension and thus reduce a list to the sum of its elements: total = 0 [total := total + x for x in [1, 2, 3, 4, 5]] # total = 15 This: Initialises a variable total to 0
