What does True do in this code ?

my_list = []
swapped = True
num = int(input("How many elements do you want to sort: "))

for i in range(num):
val = float(input("Enter a list element: "))
my_list.append(val)

while swapped:
swapped = False
for i in range(len(my_list) - 1):
if my_list[i] > my_list[i + 1]:
swapped = True
my_list[i], my_list[i + 1] = my_list[i + 1], my_list[i]

print("\nSorted:")
print(my_list)
