for文の continue break else

Last updated at 2020-01-03Posted at 2020-01-03

players = ['勇者', '戦士', '魔法使い', '僧侶']
for player in players:
    print(player)

実行結果

勇者
戦士
魔法使い
僧侶

無理やりwhile文で書くと

players = ['勇者', '戦士', '魔法使い', '僧侶']
i = 0
while i < len(players):
    print(players[i])
    i += 1

else

players = ['勇者', '戦士', '魔法使い', '僧侶']
for player in players:
    print(player)
else:
    print('終了')

elseの実行結果

勇者
戦士
魔法使い
僧侶
終了

break

players = ['勇者', '戦士', '魔法使い', '僧侶']
for player in players:
    if player == '魔法使い':
        break
    print(player)
else:
    print('終了')

breakの実行結果

勇者
戦士

while文の場合と同様に、
breakでループを抜けるとforループ全てから抜けてしまうので、
else以下は実行されない。

continue

players = ['勇者', '戦士', '魔法使い', '僧侶']
for player in players:
    if player == '魔法使い':
        continue
    print(player)
else:
    print('終了')

contiuneの実行結果

勇者
戦士
僧侶
終了
