How can i get the size of a pandas Series?-CodePudding

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 for calculus.

Thank you for your help!

CodePudding user response：

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).

CodePudding user response：

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)

CodePudding user response：

Use len or Series.size:

y_test = pd.Series(range(20))

print(len(y_test))
20

print(y_test.size)
20
