Python3 標準入力 まとめてみた

Last updated at Posted at 2020-02-02

はじめに

競技プログラミングを最近始めたので案外めんどくさい標準入力についてまとめました。
出力とかの処理についてはあとできれいに直します。

input高速化

高速化
import sys
input = sys.stdin.readline

#単純な入力

input
apple
orange 
10
12.5
a = input()
b = str(input())
c = int(input())
d = float(input())

List型

input
1
2
3
4
5
X = [int(input()) for i in range(5)]
print(X)
output
[1, 2, 3, 4, 5]
input
1 2 3 4 5
A = list(map(int,input().split()))
print(A)
output
[1, 2, 3, 4, 5]

List in 〇〇

List in tuple

l = []
n = int(input())
for i in range(n):
    a,b=input().split()
    l.append((int(a), b))

List in list(int)

n = int(input())
arr = []
for i in range(n):
    arr.append(list(map(int, input().rstrip().split())))

List in list(str)

N = int(input()) 
arr = [list(map(str, input().split())) for i in range(N)]
