QUESTION
I have been working with some code that is meant to print a poem. The goal of the code is to make borders that will fit the poem's size. But that does not pertain to my issue. I have been trying to get the code to reprint a file, line for line, but ValueError: I/O operation on closed file.
is all that is returned.
I've attempted to get around this by reopening the file after it's closed, and reopening it after the def poemprint(poem):
function has completed. But both methods have failed. I don't know where to go from here.
ANSWER
Answered 2019-Feb-09 at 20:46Your steps are:
- You open a file in
harlem
variable - You call
poemprint
function withharlem
argument. Thisharlem
is referenced aspoem
inside of the function. - You close the file that
poem
references to (it isharlem
outside of the function) - You create a new variable
harlem
that exists only inside of the function - After the function is done, you have
harlem
as a closed file
This happens because harlem
in the poemprint
and the one outside are different objects.

Install syrupy
You can use syrupy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
