Question

I had a doubt on comparision operator in python. I would like to know if it’s right or wrong.

I have certain output that is assigned to a variable. So let’s say:

result1, result2, result3

Now I do a comparison like

if result1 == 0 and result2 == 0 and result3 == 0: 
    print "Success "
else:
    print "failure"

My doubt is can this comparison done in this format

if 0 in (result1 , result2 ,result3):
    print "Success"
else :
    print "failure"

Is this right using Python? If not, then what’s the reason?

Answer 1

if 0 in (result1, result2, result3):

is equivalent to:

if result1==0 or result2==0 or result3==0:

What you want is this:

if (0,0,0) == (result1, result2, result3):

Which is equivalent to:

if result1==0 and result2==0 and result3==0:

You could actually even do this:

if result1==result2==result3==0:

since you’re checking to see if all 3 variables equal the same thing.
