如何从 Codeforces 获取多行输入？

Question

Codefores requires a lot of multi-line input. For example:

https://codeforces.com/contest/71/problem/A

TLDR: read this and reduce length of all words:

4
word
localization
internationalization
pneumonoultramicroscopicsilicovolcanoconiosis

I used this solution, which I believe is correct and works for me:

lines = []
while True:
    line = input()
    if line:
        lines.append(line)
    else:
        break
input = '\n'.join(lines)


tab=input.splitlines()

numb=tab[0]

tab.pop(0)

for i in tab:
    wordTab=[]
    if len(i)>10:
        wordTab.append(i[:1])
        wordTab.append(i[-1:])
        print(f"{i[:1]}{len(i)-2}{i[-1:]}")
    else:
        print(i)

Yet i got an error (on their side). How can I make Codeforces accept multi-line input in Python?

Answer 1

I have a setup where I have two files called "input.txt" and "output.txt". That is where I write the code locally and then I have a FILE params which I make it True and False when I have to submit to Codeforces. Here is an example of the same problem you had mentioned. It worked fine with 77 ms as running time.

import sys
from os import path

FILE = False # if needed change it while submitting

if FILE:
    sys.stdin = open('input.txt', 'r')
    sys.stdout = open('output.txt', 'w')

def get_int():
    return int(sys.stdin.readline())

def get_string():
    return sys.stdin.readline().strip()

n = get_int()

final_result = []
for i in range(n):
    word = get_string()
    if len(word) > 10:
        word = word[0] + str(len(word) - 2) + word[-1]
    final_result.append(word)

for item in final_result:
    sys.stdout.write(item)
    sys.stdout.write('\n')

Answer 2

Here is my answer

n = int(input())
arr = []
 
for i in range(n) :
    word = input()
    if len(word) > 10 :
        arr.append(word[0] + str(len(word) - 2) + word[len(word)-1])
    else :
        arr.append(word)
 
print("\n".join(arr))

Answer 3

lines = '''4 word localization internationalization pneumonoultramicroscopicsilicovolcanoconiosis''' input = '\n'.join(lines) tab=lines.splitlines() for i in tab: wordTab=[] if len(i)>10: start= i[:1] middle = len(i)-2 end= i[-1:] print(f"{start}{len(i)-2}{end}") else: print(i)
