If, multiple ifs execute multiple branches after testing, while the elifs are mutually exclusivly, execute acutally one branch after testing. 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. 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 I just started python programming, and i'm wondering about the elif keyword Other programming languages i've used before use else if
