What does this comma imply?

Question

Here's the relevant lines in my code...

data = pd.DataFrame(data, dtype = int16)
data = data.values
test = data[4]
print("Shape: " + str(test.shape))

Shape: (4087L,)

Why is there a comma after the L and what does that mean about how my data is stored?

Answer 1

Oh, ok I found the answer.

I did a head() and got an error that numpy.ndarray didn't have attribute head.

So I googled numpy array comma and found that it's shape is always a tuple and you always get a comma after a 1D tuple.

Live and learn eh. :)
