输入输出模板·Python

测试入口

• 每调用一次 input()，就会读入一行
• 如果不确定有多少行的话，还是用 sys.stdin 方便
• input() 和 sys.stdin.readline 返回的都是字符型，如果是int，float类型则需要强制转换
• 如果用 map() 批量转换的话，前面要加 list()，也就是list(map( x, xxx))
• 字符串转 list 用 .split() 分割，逗号间隔的话，用 .split(’,’)
• 如果有的行后面有空格作为结尾的话，再加上 .strip()

无限二数和

while True:
	try:
		a, b = map(int, input().split())
		print(a+b)
	except:
		break

while True:
    try:
        nums = [int(x) for x in input().split()]
        print(sum(nums[1: ]))
    except:
        break

import sys
for line in sys.stdin:
	ls = list(map(int, line.split()))
	print(ls)

import sys
n = int(input())
for line in sys.stdin:
    l = line.split()
    l.sort()
    # print(' '.join(l))
    print(','.join(l))

有限二数和

N = int(input())
for _ in range(N):
	a, b = map(int, input().split())
	print(a + b)

while True:
	try:
		a, b = map(int, input().split())
		if a == 0 and b == 0:
			break
		print(a + b)
	except:
		break

while True:
	try:
		nums = [int(x) for x in input().split()]
		if nums[0] == 0:
			break
		print(sum(nums[1:]))
	except:
		break

N = int(input())
for _ in range(N):
	nums = [int(x) for x in input().split()]
	print(sum(nums[1:]))

字符排序

N = int(input())
words = [x for x in input().split()]
words.sort()
# print(" ".join(words))
print(",".join(words))

多个整数输入

N = int(input())
for i in range(N):
	ls = list(map(int, input().split()))
	print(ls)
