How to convert list of tuples to multiple lists?
...e the result:
zip: 122.11585397789766
append: 356.44876132614047
list comp: 144.637765085659
So if you are after performance, you should probably use zip() although list comprehensions are not too far behind. The performance of append is actually pretty poor in comparison...
