Try to put a 'r' letter before the opening-quote:
print \
r"""
_____ ___ ___ ___ _____
/ ___| / | / |/ | | ___|
| | / /| | / /| /| | | |__
| | _ / __| | / / |__/ | | | __|
| |_| | / / | | / / | | | |___
\_____/ /_/ |_| /_/ |_| |_____|
_____ _ __ ______ _____
/ _ \ | | / / | ____| | _ \
| | | | | | / / | |__ | |_| |
| | | | | | / / | __| | _ /
| |_| | | |/ / | |____ | | \ \
\_____/ |___/ |______| |_| \_\
"""
Python was trying to interpret the '\'.
