check_roration.py

# this is a easy problem you know how rotation works.
# this problem can be sloved using index()

def check_rotation(string1, string2):
    if len(string1) != len(string2): # check for base case
        return "No"
    
    con = string1*2       # concatenate string with itself
    if con.count(string2) > 0:    # check for string2 in concatenated string
        return "Yes"
    else:
        return "No"

string1 = "awesomepython"   # original string
string2 = "pythonawesome"   # rorated string
print(check_rotation(string1, string2))

# the output will be "Yes"
