Hello,
I was currently going through the fastai book (very fruitful read) and came across the following syntax:
plt.plot(L(learn.recorder.values).itemgot(2));
Digging deeper I found that the L was a specific class to the fastai library. I experimented with the function a bit and saw the following changes.
I was confused as to how the structure changed in such a way. What does the L class do to the list and what do the hashtag numeric values signify?
