Should you have multiple returns in a function?

Should you have multiple returns in a function?

Dijkstra said that every function, and every block within a function, should have one entry and one exit. So, if you keep your functions small, then the occasional multiple return, break, or continue statement does no harm and can sometimes even be more expressive then the single-entry, single-exit rule.”

Should a method only have one return?

It is sometimes said that a method should have only one return statement (i.e. one exit point) and that to code using more than one return per method is bad practice. It is claimed to be a risk to readability or a source of error. Sometimes this is even given the title of the “single exit point law”.

Is it bad to have multiple returns in a function?

In a function that has no side-effects, there’s no good reason to have more than a single return and you should write them in a functional style. In a method with side-effects, things are more sequential (time-indexed), so you write in an imperative style, using the return statement as a command to stop executing.

Can we have 2 return statements?

Yes, just a return statement and that’s it. No other operators or statements. Multiple return statements in a method will cause your code not to be purely object-oriented. The answer may surprise you: In a pure object-oriented world, a method must have a single return statement and nothing else.

Can a method have no return statements?

Any method declared void doesn’t return a value. It does not need to contain a return statement, but it may do so. The data type of the return value must match the method’s declared return type; you can’t return an integer value from a method declared to return a boolean.

Can we return multiple values from a function in Python?

You can return multiple values by bundling those values into a dictionary, tuple, or a list. Python functions can return multiple values. To return multiple values, you can return either a dictionary, a Python tuple, or a list to your main program.

How many values can a function return at a time?

Even though a function can return only one value but that value can be of pointer type.
