<bot>: Here is a Python program to compare two strings for percent similarity

import string

def _percent_similarity(s1, s2):
 """Returns the percent similarity between two strings."""
 return (len(s1) + len(s2) - len(s1.replace(s2, ""))) / (len(s1) + len(s2))

# Enter the strings
s1 = "hello"
s2 = "hello"

# Calling the function
print((_percent_similarity(s1, s2)))

#Example Output
# 1.0

#Remember to inspect code for bugs.
