If, multiple ifs execute multiple branches after testing, while the elifs are mutually exclusivly, execute acutally one branch after testing. Print(f{a} es divisible entre 5) if a % 3 == 0 0 elif is a bit more efficient, and it's quite logical

With if s the program has to evaluate each logical expression every time
In elif s though, it's not always so
However, in your example, this improvement would be very, very small, probably unnoticeable, as evaluating x > 0 is one of the cheapest operations. 2 o if serve para verificar uma condição e o elif serve para verificar outra condição caso a condição do if seja falsa No código não há muita diferença, o elif vai garantir que aquela condição seja verificada caso o if seja falso, diferente dos dois if que são 'fluxos' independentes. I just started python programming, and i'm wondering about the elif keyword
Other programming languages i've used before use else if Does anyone have an idea why the python developers added the Assuming the invalid syntax is a typo, the big benefit of elif vs having an else statement with a nested if is indentation Each time you go into a nested if you'll need to indent again, which will destroy readability.
Elif seems to have originated with the c preprocessor, which used #elif long before python afaict
The other side of it is that for if/elif/else the performance will vary based on how the data is sorted, and whether it checks the most occurring condition first.

Hay una diferencia fundamental, si usas if encadenados todas las expresiones son evaluadas siempre, aunque una previa sea cierta A = 15 if a % 5 == 0
