Challenge: Print baby shark with less than 300 characters of code.

baby-shark.py

def baby_shark_lyrics():
    a,o=[],''
    for s in 'Baby Mommy Daddy Grandma Grandpa'.split():
        a+=[s+" shark"]
    a+=["Let's go hunt"]
    for i in a:
        o+=(i+","+" doo"*6+"\n")*3+i+"!\n"
    return o+'Run away,…'

print(baby_shark_lyrics())

Fun fact. The size of the script is only ~30% of the actual lyrics.
