OJ 说我的 python 程序编译错误，即使它在我的电脑上运行良好 (ubuntu 18.04)

Question

i wrote a simple python program for my homework that wants us to add up three integers given from input. i submitted it to my school's oj (online judge) system, but i got "compiler error"

the program runs very well on my personal computer that runs ubuntu 18.04 amd64, but i can't get it pass the oj test. i sincerely don't know what went wrong because the oj didn't give any message, only a final status "compiler error"

import sys

a = input()
b = input()
c = input()
a = int(a)
b = int(b)
c = int(c)
answer = a + b + c
print(f"The answer is {answer}")

here's the result when i run my program on my computer:

ubuntu@VMware:~/python-intro $ python3 1003.py
3
4
5
The answer is 12

and my computer system:

ubuntu@VMware:~/python-intro $ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS
Release:        18.04
Codename:       bionic

how can it be a compiler error on the oj?? i have confirmed that my submission language is "python 3" not "python 2" or whatever.

Answer 1

Maybe the python 3 version of your OJ is not python 3.6. And you can't use f-string on python versions below 3.6.

I suggest to change your string format to:

print("The answer is {answer}".format(answer=answer))

Answer 2

f-strings were introduced in Python 3.6. In an earlier Python, this line is a syntax error:

print(f"The answer is {answer}")

To ensure compatibility, rewrite it to

print("The answer is %s" % answer)

Answer 3

The problem is mostly related to f-string as Amadan pointed out.

print(f"The answer is {answer}") <<<

change this with format usage and update the thread.

print("The answer is {}".format(answer))
