Question

我正在尝试使用if...and语句检查是否满足了两个条件：

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

但它总是回归正面。为什么呢？

以下是完整的代码：

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

Answer 1

foo和bar的价值到底是什么？
工作示例：

a = 'True' 
b = 'True'

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

c = 'Hello'
d = 'Hello'

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

if的多个条件
