array_count

Task
King Arthur and his knights are having a New Years party. Last year Lancelot was jealous of Arthur, because Arthur had a date and Lancelot did not, and they started a duel.
To prevent this from happening again, Arthur wants to make sure that there are at least as many women as men at this year's party. He gave you a list of integers of all the party goers. 
Arthur needs you to return true if he needs to invite more women or false if he is all set.
Input/Output
[input] integer array L ($a in PHP)
An array (guaranteed non-associative in PHP) representing the genders of the attendees, where -1 represents women and 1 represents men.
2 <= L.length <= 50
[output] a boolean value
true if Arthur need to invite more women, false otherwise.

solution -
def invite_more_women(arr):
    return True if arr.count(1) > arr.count(-1) else False
