The important part here is, that I used an infinite while loop to accept input which gave me a runtime error. $ python3 main.py < empty.txt Python Among Us You are a . A while block is used within a try block, which is evaluated to true, and as long as the condition is true, the data provided by the user is read, and it is displayed using a print statement, and if the data cannot be read with an empty string being returned, then the except block raises an exception with the message which is shown in the output. We will go through few examples that show when the unexpected EOF while parsing error occurs and what code you have to add to fix it. To fix this error you can add an except or finally block. The negative integer EOF is a value that is not an encoding of a "real character" . One problem often encountered when working with file data is the representation of a new line or line ending.
