Question

def Fitness(a, b, c):  
    if ((a&b&c) >= 4) & ((a+b+c) >= 13):  
        return('Gold')  
    if ((a&b&c) >= 3) & ((a+b+c) >= 10):  
        return('Silver')   
    if ((a&b&c) >= 2) & ((a+b+c) >= 07):  
        return('Pass')  
    else:  
        return('Fail')

now the Problem is when Fitness(2,2,5) is given, the control jumps to default ie. ‘Fail’.
Where is the actual output is ‘Pass’. ?

Answer 1

Note that

a&b&c >= 2

is different from

a>=2 and b>=2 and c>=2.

I think you mean the second one, i.e. all values are larger than two. (The first one does a binary and with all your values and compares this to the value two.)
