Count the Smiley Faces :)

Create a function that takes a list of strings and return the number of smiley faces contained within it. These are the components that make up a valid smiley:

• A smiley has eyes. Eyes can be : or ;.
• A smiley has a nose but it doesn't have to. A nose can be - or ~.
• A smiley has a mouth which can be ) or D.

No other characters are allowed except for those mentioned above.

Examples

count_smileys([":)", ";(", ";}", ":-D"]) ➞ 2

count_smileys([";D", ":-(", ":-)", ";~)"]) ➞ 3

count_smileys([";]", ":[", ";*", ":$", ";-D"]) ➞ 1

Notes

• You will always be given a list as input.
• An empty list should return 0.
• The order of each facial element will always be the same.
• Noses are optional (e.g. :) and :-) are both valid).
