Exact output was coming but some error was raising

In the above Python code the exact output was coming but after output they were showing some error

    def main():
    i=1
    while i < 3:
     
     inputString = input()
     inputStringTwo = input()
     inputStringThree = input()
     outputString=inputString[0] + inputStringTwo[0] + inputStringThree[0]
     print(outputString)
     i+=1

main()

Here we are giving input as

Very
Important
Person

The Error was

VIP

Traceback (most recent call last):
  File "main.py", line 15, in <module>
    main()
  File "main.py", line 5, in main
    inputString = input()
EOFError: EOF when reading a line

Here VIP is the output

Answer

if you are using an online IDE;

EOFError is raised when one of the built-in functions input() or raw_input() hits an end-of-file condition (EOF) without reading any data. This error is sometimes experienced while using online IDEs. (https://www.geeksforgeeks.org/handling-eoferror-exception-in-python/)

try not to use online IDEs its better to download python
