Converting list of tuples into a dictionary

Question

I\'m looking for a way to convert a list of tuples like this:

[(1,4),(2,4),(3,4),(4,15),(5,15),(6,23),(7,23),(8,23),(9,15),(10,23),(11,15),(12,15)]
         


        

Answer 1

for key, value in tuples:
    if d.get(key):
        d[key].append(value)
        continue
    d[key] =[value]
