How can i get the size of a pandas Series?
Question:
I have a pandas series test set y_test. I want to get its size for statistics.
Using this code :
print(y_test.shape)
I get
(31054,)
I want to get 31054
Answers:
Use len or Series.size:
y_test = pd.Series(range(20))
print(len(y_test))
20
print(y_test.size)
20
y_test.shape gives you a tuple.
So you can do print(y_test.shape)[0] to get the first element in the there which is the size of the Series.
shape gives you a tuple because it comes from dataframes which give you the shape of the frame in (rows, columns).
You could either
size = y_test.shape[0]
Which will give first element of the tuple, which is size.
Or you could get it directly using size attribute or the len() method.
size = y_test.size
#or
size = len(y_test)
