How to close an already opened file?

[madhavpr]

Hi,

I'm trying to read EEG signals and I'm quite new to this field. I ran the following script.

f = pyedflib.EdfReader("chb01_01.edf")
print(f)
n = f.signals_in_file
print("number of signals in file:", n)
signal_labels = f.getSignalLabels()
print("signal_labels:", signal_labels)

It worked fine when I ran it for the first time. However, if I run it again, I get the following error:

IOError: file has already been opened

I have tried inserting 1. f._close() 2. f._close() followed by del f, after the print("signal_labels..... ) function but failed. Is there a way to fix this error? Thanks a lot

Should work now
In order to close, do the following:

f._close()
del f
