🔒 Program stopping prematurely

[tacit geyser]

instructions: Please write a program which asks the user for a positive integer number. The program then prints out a list of multiplication operations until both operands reach the number given by the user. See the examples below for details:

num = int(input("Please type in a number:"))
a = 1
b = 1
while a != num and b != num:
    print(f"{a} x {b} = {a*b}")
    while b != num:
        b += 1
        print(f"{a} x {b} = {a*b}")
    b = 1
    a += 1```

im not sure why the program is stopping already

the while conditions havent been met yet

a is == num but b isnt yet

isnt the program supposed to keep running til both are == num

Please type in a number:4
1 x 1 = 1
1 x 2 = 2
1 x 3 = 3
1 x 4 = 4
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12

my code output

The screenshot here is an example?

[tacit geyser]

its my code inside a python viewer tool thingy

See the examples below for details:
Can you share the examples its referring to?

[timber iris]

ah ok that makes sense now

[digital wing]

I would use for loops and range to accomplish this instead. Would make the program a lot simpler and easier to understand. And it would fix the issue you're having as well.

[tacit geyser]

those concepts havent been introduced in this part of the course yet so I was hoping to do it with a while loop

[digital wing]

Ah okay.

[timber iris]

maybe while a < num ... ?

[tacit geyser]

theres a lot of problems in this course that would be a lot easier with range and stuff 😭 but I figured it felt a bit like cheating

[tacit geyser]

I'll try that thank you!

[timber iris]

They challenge you to do that on purpose

[tacit geyser]

Yeah I figured

[tacit geyser]

i get the same output weirdly enough

[timber iris]

a < num + 1 and b < num + 1 ?

[digital wing]

Changing the outer while to while not a > num: worked for me

[tacit geyser]

they worked tysm guys!

I need help in understanding why my code didnt work though

I still dont get why the program seemed to stop before the conditions were met

[timber iris]

well think about it

if while a < num means while 4 < 4 it would stop before 4

not on 4

or in PeachTeaEnjoyer's case
while not a > num is equivalently read as while not 4 greater than 4

which is True

until it goes while not 5 greater than 4, thats False and stops there

[tacit geyser]

I see

thank you so much!
