hi i need help the ;last part is not retunred and i have no idea... thank you

According to this xkcd cartoon you shouldn't date someone whose age is less than half your own age plus 7. Write a boolean-valued function can_date(age1, age2) that takes the ages of two people and return True if they can date, according to xkcd's rule.

Notes:

• The ages are not in any particular order - the bigger one may be either first or last.
• Assume integer division so that, for example, a 19-year-old can date a 16-year-old because we take half of 19 to be 9 not 9.5.

def can_date(age1, age2):
"""return"""
if age1 // 2 + 7 == age2:
return True
elif age2 // 2 + 7 == age1:
return True
elif age1 == age2:
return True
else:
return False


everthing returns except the all good

print(can_date(24, 19))	True	True
	print(can_date(19, 24))	True	True
	print(can_date(24, 18))	False	False
	print(can_date(16, 16))	True	True
	print(can_date(14, 16))	False	False
	print(can_date(16, 15))	True	True
	print(can_date(73, 43))	True	True
	print(can_date(42, 73))	False	False
	run_lots_of_tests()	All good	can_date(1, 1) returned True, should be False

You have told the program to return `True` if the numbers equal each other. This code should work.

def can_date(age1, age2):
    """return"""
    if age1 // 2 + 7 == age2:
       return True
    elif age2 // 2 + 7 == age1:
       return True
    elif age1 == age2:
       return False
    else:
       return False
