select all the span text with same attribute

[JennyYang]

after finding all spans in the object I get the results as following.
I would like to choose the different values using:
rating_chart[31].find('span',attrs={'class':"_3fVK8yi6"}).getText()

but it only shows the first answer: 1961. How do I get all the numbers: 1961, 437,116,40?

Thank you so much.

results:
