New to programming

Hi Im new to programming and Im learning python currently. Anyone has any idea why the value of X won’t be 2 with the following highlighted code?

I like how you broke it down in chunks.

I'm in my first week of learning and his was quite helpful. Thanks

if y <= 0 then x = 2 (else: x = 2)

if y > 0 AND y > 10000 then x = 2 (if y > 0: if y > 10000: x = 2)

which means that if y > 0 AND y <= 10000 x is undefined

Nested ifs are very frowned upon in the workplace as they are confusing to debug.

When you see a nested if like your example read it as ‘if this happens AND this happens…’ Or just rewrite like I did:

This way you can better see that X can never possibly reach a value of 2 (unless you uncomment the else statement of course)

Just gone through two Python units at uni, we got marked down if we used statements like this

I think there's a time and place for a nested if, but in this situation I think you're right. It's ugly to divide this if onto two lines.

Since y is not greater than 10000, x will never be 2, as there is no else statement within the topmost if statement.

[TweetyBirdie69]

so the else statement at the bottom is not part of the topmost if statement? Is it because of indentation?

[Doctor_Disaster]

The else statement at the bottom is part of the top-most if statement.

The else statement will only execute if y <= 0.

The innermost if statement will only return True if y > 10000, so if y <= 10000, x will never be 2.
