multiple conditions with if

Question

I'm trying to check that two conditions are fulfilled with an if...and statement:

if foo < 0 and bar < 0:
    #do something

but it's always returning positive. Why?

Here is the complete code:

loop = 1
while loop == 1:
    t = raw_input("Please enter a number.")
    d = raw_input("Please enter another number")
    limit = raw_input("Please enter another number")
    try:
        t = int(t)
        d = int(d)
        limit = int(limit)
        loop = 0
    except ValueError:
        print "Sorry, but one of those was an invalid input. Please ensure you enter only numbers greater than zero."
    if t > 0 and d > 0:
        loop = 0
    else:
        pass

What exactly is the value that you have in foo and bar ?
Working example:

a = 'True' 
b = 'True'

if (a and b):
    print('Both True')

c = 'Hello'
d = 'Hello'

if (c == d):
    print('Equal')
