What data type is pattern in 'A Relay of Phases'

In the introduction, it lists it as an array, but in the function definition is has it as a float. What can we expect the data type to be?

Hi @ccadena!
You are correct, there is a discrepancy between the challenge description and the functions’ docstring. The data type for pattern is an array, as indicated by the public test cases in the description.
Thanks for letting us know, and good luck with the challenge!
