Nested Loops - Python

01. Clock

for h in range(24):
    for m in range(60):
        print(f"{h}:{m}")

========================================
02. Multiplication Table

for i in range(1, 11):
    for j in range(1, 11):
        print(f"{i} * {j} = {i * j}")
================================================================================
03. Combinations

n = int(input())

count = 0
for x1 in range (n + 1):
    for x2 in range(n + 1):
        for x3 in range(n + 1):
            sum = x1 + x2 + x3

            if sum == n:
                count += 1

print(count)

================================================================================
04. Sum of Two Numbers

start = int(input())
end = int(input())
magic_num = int(input())

flag = False
count = 0
for i in range(start, end + 1):
    for j in range(start, end + 1):
        sum = i + j
        count += 1

        if sum == magic_num:
            print(f"Combination N:{count} ({i} + {j} = {sum})")
            flag = True
            break

    if flag:
        break

if not flag:
    print(f"{count} combinations - neither equals {magic_num}")

================================================================================
05. Travelling

destination = input()

while destination != "End":
    price_trip = float(input())

    sum_current_destination = 0
    while sum_current_destination < price_trip:
        saved_money = float(input())
        sum_current_destination = sum_current_destination + saved_money

    print(f"Going to {destination}!")

    destination = input()

================================================================================
06. Building

floors = int(input())
rooms = int(input())

#floors = 6
#rooms = 4

for f in range(floors, 0, -1):
    for r in range(0, rooms):

        if f == floors:
            print(f"L{f}{r}", end=" ")
        elif f % 2 == 0:
            print(f"O{f}{r}", end=" ")
        else:
            print(f"A{f}{r}", end=" ")

    print()
