牛客OJ在线编程常见输入输出练习（python版）

先放上地址：https://ac.nowcoder.com/acm/contest/320#question

1、A+B(1)

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

2、A+B(2)

while True:
    try:
        l = list(map(int, input().strip().split()))
        if len(l) == 1:
            pass
        else:
            print(sum(l))
    except EOFError:
        break

3、A+B(3)

while True:
    try:
        l = list(map(int,input().strip().split()))
        if l == [0,0]:
            break
        else:
            print(sum(l))
    except EOFError:
        break

4、A+B(4)

while True:
    try:
        l = list(map(int, input().strip().split()))
        if l[0] == 0:
            break
        else:
            print(sum(l[1:]))
    except EOFError:
        break

5、A+B(5)

while True:
    try:
        l = list(map(int,input().strip().split()))
        if len(l) == 1:
            pass
        else:
            print(sum(l[1:]))
    except EOFError:
        break

6、A+B(6)

while True:
    try:
        l = list(map(int, input().strip().split()))
        print(sum(l[1:]))
    except EOFError:
        break

7、A+B(7)

while True:
    try:
        l = list(map(int, input().strip().split()))
        print(sum(l))
    except EOFError:
        break

8、字符串排序（1）

while True:
    try:
        n=int(input())
        mystr=list(map(str,input().strip().split()))
        mystr.sort()
        print(' '.join(mystr))
    except EOFError:
        break

9、字符串排序（2）

from fileinput import input
for line in input():
    a = line.split()
    a = sorted(a)
    s = ''
    for i in range(len(a)-1):
        s+=a[i]+' '
    s += a[-1]
    print(s.lstrip())

10、字符串排序（3）

from fileinput import input
for line in input():
    a = sorted(line.strip().split(','))
    s = ''
    for i in range(len(a)-1):
        s+=a[i]+','
    s += a[-1]
    print(s)
