inserting value into strings

[Saxycool12345]

In the print() function you are telling Python to concatenate (add) two strings, 'B' and 'G', yet you have defined them as integers. 

>>> x = 'hello'
>>> y = 'world'
>>> x + y
'helloworld'
>>>

Since you are using Python 3.6.2, you should look into formatting. So your print() function would look like this:

print("your compatibillity is {} %".format(B + G))

Also, you have defined a function "Love", which you do not use. If B, G and "print" are meant to be part of the function, they need to be properly indented and the function called:

def love():
    B = int(len(input("please put your name: ")))
    G = int(len(input("please put the name of your love interest: ")))
    print("your compatibility is {} %".format(B + G))

love()

Output:
C:\Python36\python.exe C:/Python/Games/scratch.py
please put your name:joe
please put the name og your love interest:sally
your compatibility is 8 %
