How to separate a Python list into two lists, according to some aspect of the elements

Question

I have a list like this:

[[8, \"Plot\", \"Sunday\"], [1, \"unPlot\", \"Monday\"], [12, \"Plot\", \"Monday\"], [10, \"Plot\", \"Tuesday\"], [4, \"unPlot\", \"         


        

Answer 1

data = [[8, "Plot", "Sunday"], [1, "unPlot", "Monday"], [12, "Plot", "Monday"], [10, "Plot", "Tuesday"], [4, "unPlot", "Tuesday"], [14, "Plot", "Wednesday"], [6, "unPlot", "Wednesday"], [1, "unPlot", "Thursday"], [19, "Plot", "Thursday"], [28, "Plot", "Friday"], [10, "unPlot", "Friday"], [3, "unPlot", "Saturday"]]

res = {'Plot':[],'unPlot':[]}
for i in data: res[i[1]].append(i)

This way you iterate the list once
