style or format question regarding input as integers

I want to develop good habits upfront.

Coders are always muttering about poorly structured code, so I am hypersensitive to not only learning to code, but wanting to learn it the right way up front to avoid being the person others are muttering about. :-)

In the team.py exercise, there are a few times where I got the correct result but it was written differently from the teacher's solution. I appreciate feedback on these two examples on which is the more acceptable or preferred style. They both work.

Thanks for the replies and helping me develop the best coding behaviors upfront... Donne

First Comparison: (comment - I took to heart the DRY approach, maybe too literally?)

MINE:

while True:
    add_player = input("\nWould you like to add a player to the list?  (Yes/No)    ")
    if add_player.lower() == "no":
        break
    else:
        name = input("Enter the name of the player to add to the team:    ")
        players.append(name)

TEACHER:

add_players = input("Would you like to add a player to the list?  (Yes/No)    ")
while add_players.lower() == 'yes':
    name = input("\nEnter the name of the player to add to the team:    ")
    players.append(name)
    add_players = input("Would you like to add a player to the list?  (Yes/No)    ")

Second Comparison: (comment - I didn't see a need to create a function, seemed like something else to maintain, but I could have used it.)

MINE:

for number in range(len(players)):
    print("Player", number+1, ":  {}".format(players[number]))

TEACHER:

player_number = 1
for player in players:
    print("Player {}: {}".format(player_number, player))
    player_number += 1

Third Comparison: (comment - this is a question of pure correctness. is it better to include int on the input line? Would it be easier for others who come after me to find and maintain it on the second line?)

MINE:

keeper = int(input("\nPlease identify the goal keeper by selecting the player number. 1-{}:  ".format(len(players))))

TEACHER:

keeper = input("Please select the goal keeper by selecting the player number. (1-{})".format(len(players)))
keeper = int(keeper)
