If, multiple ifs execute multiple branches after testing, while the elifs are mutually exclusivly, execute acutally one branch after testing. That's where elif comes in handy to prevent such thing from happening, which is the primary benefit of using it The other secondary good benefit of using elif instead of multiple if 's is to avoid confusion and better code readability. 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
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 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.
Up until now, i have only used if and else in list comprehension, as in if/else in a list comprehension. 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 Print(f{a} es divisible entre 5) if a % 3 == 0 Print(f{a} es divisible entre 3) 15 es divisible entre 5 15 es divisible entre 3 si usas elif, en el momento que una condición anterior (el if u otro elif) se cumpla, ese elif y el resto que. According to the official python tutorial, only one block of an if.elif.else structure will be executed
Your current if.if.if construct will evaluate all possibilities and execute any that are true.
