本博客用来记录python3版本的常见输入输出。

2 训练

题目1：A+B(1)

python3代码如下，

import sys for line in sys.stdin:a, b = map(int, line.split())print(a+b)

题目2：A+B(2)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for i,line in enumerate(lines):if i != 0:a, b = map(int, line.split())print(a+b)

题目3：A+B(3)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:a, b = map(int, line.split())if a != 0 and b != 0:print(a+b)

题目4：A+B(4)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:nums = line.split()nums = [int(x) for x in nums]if nums[0] != 0:print(sum(nums[1:]))

题目5：A+B(5)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for i,line in enumerate(lines):if i != 0:line = line.split()line = [int(x) for x in line]print(sum(line[1:]))

题目6：A+B(6)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:line = line.split()line = [int(x) for x in line]print(sum(line[1:]))

题目7：A+B(7)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:line = line.split()line = [int(x) for x in line]print(sum(line))

题目8：字符串排序(1)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
words = lines[1].split()
words.sort()
res = " ".join(words)
print(res)

题目9：字符串排序(2)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:words = line.split()words.sort()res = " ".join(words)print(res)

题目10：字符串排序(3)

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
for line in lines:words = line.split(',')words.sort()res = ",".join(words)print(res)

题目11：自测本地通过提交为0

python3代码如下，

import sys s = sys.stdin.read()
lines = s.splitlines()
a, b = map(int, lines[0].split())
print(a+b)
