What is the problem here

Question

while True:
A=int(input("saisir un entier"))
B=int(input("saisir un 2 entier"))
if (10<=A<=60) and (10<=B<=60):
break

Answer 1

When using mutiple conditions, you have to hardcode each variable and use logical operators.

if (10 <= A <= 60)
# should be
if (A >= 10 and A <= 60)

Same with the second condition on variable "B".

Because for example A is 70:
if (10 <= 70 <= 60)
if (1 <= 60)
>> True

The interpreter will run the condition left to right and it will first evaluate 10 <= 70 which is True so 1 (truthy).
Then, 1 <= 60 is True though 70 in fact, is not between 10 and 60.
