#python で配列を持ったディクショナリのキーがある場合は for ループを回して、逆にない場合は何もしない例

Last updated at Posted at 2019-05-19

get の第二引数に初期値の配列を渡しておく

( some_dict.get('some_key', []) )

people = {'family': ['alice','bob','carol']}

for person in people.get('family', []):
  print(person)

# alice
# bob
# carol

for person in people.get('workers', []):
  print(person)

# (nothing)
