How do I get the

Easy, strip out the exception handling you have above.
c:\Users\Mark\MyPython>type a.py
with open('nosuchdirectory/text/truthyfalsey.txt') as fh:
for line in fh:
print(line,end='')
c:\Users\Mark\MyPython>a
Traceback (most recent call last):
File "C:\Users\Mark\MyPython\a.py", line 1, in <module>
with open('nosuchdirectory/text/truthyfalsey.txt') as fh:
FileNotFoundError: [Errno 2] No such file or directory:
'nosuchdirectory/text/truthyfalsey.txt'
A slight aside, note I've used the 'with' clause so there's no need to
explicity close the file, good ole Python does it for you.
