Python3: I'm Trying to merge two list in the func that my professor gave me but it just never o-CodePudding

def mergedSchedules(pers1Schedule, pers2Schedule):
    merged =[]
    i,j =0,0
    while i < len(pers1Schedule) and j< len(pers2Schedule):
        meeting1, meeting2 =pers1Schedule[i], pers2Schedule[j]
        if meeting1[0]<= meeting2[0]:
            merged.append(meeting1)
            i =1
        else:
            merged.append(meeting2)
            j =1
    while i< len(pers1Schedule):
        merged.append(meeting1)
        i =1
    while i< len(pers2Schedule):
        merged.append(meeting2)
        j =1
    return merged

pers1Schedule = [['0:00', '9:00'], ['7:00', '8:30'], ['12:00', '13:00'], ['16:00', '18:00'], ['19:00', '23:59']]
pers2Schedule = [['0:00', '9:00'], ['9:00', '10:30'], ['12:20', '14:30'], ['14:00', '15:00'], ['16:00', '17:00'], ['18: 30', '23:59']]

mergedSchedules(pers1Schedule, pers2Schedule)

It works if i use small list but it doesn't when the list is bigger i dont know if i can change the code for the func since its given by the professor but its not working.

In order to sort the merged list you really need the times (I assume that's what they are) to be normalised - i.e. HH:MM

So, with appropriately normalised data, you can do this:-

def merge(l1, l2):
    rv = l1.copy()
    for e in l2:
        if e not in rv:
            rv.append(e)
    return sorted(rv, key=lambda x: (x[0], x[1]))

pers1Schedule = [['00:00', '09:00'], ['07:00', '08:30'], ['12:00', '13:00'], ['16:00', '18:00'], ['19:00', '23:59']]
pers2Schedule = [['00:00', '09:00'], ['09:00', '10:30'], ['12:20', '14:30'], ['14:00', '15:00'], ['16:00', '17:00'], ['18:30', '23:59']]

print(merge(pers1Schedule,pers2Schedule))

list1=[pers2Schedule[0:3]]

list3=pers1Schedule list1

print(list3)
