What is a return value in Python?
In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit.
How do you show a value return in Python?
Print vs Return in Python
- Printing means displaying a value in the console. To print a value in Python, you call the print() function.
- Returning is used to return a value from a function and exit the function. To return a value from a function, use the return keyword.
Can a Python script return a value?

How do you return two values in Python?
In Python, you can return multiple values by simply return them separated by commas. As an example, define a function that returns a string and a number as follows: Just write each value after the return , separated by commas.
What is return in a function?
A return is a value that a function returns to the calling script or function when it completes its task. A return value can be any one of the four variable types: handle, integer, object, or string. The type of value your function returns depends largely on the task it performs.
What is return in coding?
In programming, return is a statement that instructs a program to leave the subroutine and go back to the return address. The return address is located where the subroutine was called.
What does -> mean in Python?
The -> (arrow) which is one of the function annotations is used to document the return value for a function. >>> def add(a: int, b: int) -> int: >>> return a+b. The -> is written after the parameters list in the declaration of the function and marks the following expression as the return type/value.
How can I return 2 values?
We can use following solutions to return multiple values.
- If all returned elements are of same type.
- If returned elements are of different types.
- Using Pair (If there are only two returned values) We can use Pair in Java to return two values.
- If there are more than two returned values.
- Returning list of Object Class.
How do you return a value?
To return a value from a function, you must include a return statement, followed by the value to be returned, before the function’s end statement. If you do not include a return statement or if you do not specify a value after the keyword return, the value returned by the function is unpredictable.

What is -> symbol in Python?
This is function annotations. It can be use to attach additional information to the arguments or a return values of functions. It is a useful way to say how a function must be used.
Can we return multiple values from a function in Python?
You can return multiple values from a function in Python. To do so, return a data structure that contains multiple values, like a list containing the number of miles to run each week. Data structures in Python are used to store collections of data, which can be returned from functions.
How do you return multiple things from a function in Python?
To return multiple values from a function in Python, return a tuple of values. A tuple is a group of comma-separated values. You can create a tuple with or without parenthesis. To access/store the multiple values returned by a function, use tuple destructuring.
What is return a value?
What is return data type?
In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method. In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function.
What is return value of a code?
Return values allow a function to return (give back) a value at the end of a function call. This ends the call to the function, continuing the code from where the function was called.
