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. ", # This and __next__() are used to create a custom iterator, # See https://dbader.org/blog/python-iterators, # See https://en.wikipedia.org/wiki/Portable_Network_Graphics#%22Chunks%22_within_the_file, # The file hasn't been opened or reached EOF. We can expect EOF in few cases which have to deal with input() / raw_input() such as: Interrupt code in execution using ctrl+d when an input statement is being executed as shown below, Another possible case to encounter EOF is, when we want to take some number of inputs from user i.e., we do not know the exact number of inputs; hence we run an infinite loop for accepting inputs as below, and get a Traceback Error at the very last iteration of our infinite loop because user does not give any input at that iteration, The code above gives EOFError because the input statement inside while loop raises an exception at last iteration. If End of file Error or EOFError happens without reading any data using the input() function, an EOFError exception will be raised. It simply means you can't use stdin for anything on that platform, so no input(), no sys.stdin.read(), (so the resolution is "don't do that", it's pretty specifically forbidden). This is typically done by assigning a numerical value to represent a character. In order to avoid this exception being raised, we can try the following options which are: Before sending the End of File exception, try to input something like CTRL + Z or CTRL + D or an empty string which the below example can demonstrate: Explanation: In the above program, try and except blocks are used to avoid the EOFError exception by using an empty string that will not print the End Of File error message and rather print the custom message provided by is which is shown in the program and the same is printed in the output as well.
