featuretools.primitives.UpperCaseCount#

class featuretools.primitives.UpperCaseCount[source]#

Calculates the number of upper case letters in text.

Description:

Given a list of strings, determine the number of characters in each string that are capitalized. Counts every letter individually, not just every word that contains capitalized letters.

If a string is missing, return NaN

Examples

>>> x = ['This IS a string.', 'This is a string', 'aaa']
>>> upper_case_count = UpperCaseCount()
>>> upper_case_count(x).tolist()
[3.0, 1.0, 0.0]
