Question

BlockPy: #35.2) Animal Splits Write a function all_cats that consumes a comma-separated string of animals and prints whether all of the animals have "cat" in their name. For example, the string "gerbil,catfish,dog,cat" would return False, but just "cat,catfish" would return True. If the function consumes an empty string, then it returns True. Call this function on a string of animals of your choice and print the result.

 return True

print(all_cats("gerbil,catfish,dog,cat"))

print(all_cats("cat,catfish"))

print(all_cats(""))
