[Atcoder]python3の入力処理方法

Last updated at Posted at 2022-04-03

3/26からAtCoder始めました。対戦よろしくお願いいたします。
AtCoderの入力方法は標準入力です。
普段、標準入力はあまりしないので、戸惑ってしまいました。
そのため、主な入力処理パターンをまとめました

入力個数が1つ(ex 1)

# int
a = int(input())
# str
a = str(input())

入力個数が決まっているパターン(ex A B C Dが与えられるパターン)

# int
a, b, c, d = map(int, input().split())
# str
a, b, c, d = str(int, input().split())

個数が指定されない場合(ex. A1~Anの個数が当たられるパターン)

# int
An = list(map(int,input().split()))
# str
Bn = list(map(str,input().split()))

1つ目に個数、2つ目以降にリストがある場合(n k1 k2 k3 .... kn)の場合

n, *kn = map(int, input().split())

文字列分割の場合

#ABCD
a = list(input())
# a = ["A","B","C","D"]

楽しく競技プログラミングしましょう!
