For example, #function definition def myFun() : return 1, 2, 3 #sample use a, b, c = myFun() print(a) print(b) print(c) #Output 1 2 3. You can return multiple values by bundling those values into a dictionary, tuple, or a list. These values are stored in the variable square. But, you can use this approach to return any collection of values. Note that, to return multiple values, you just need to write them in a comma-separated list in the order you want them returned.

Example 1: Return multiple values from the function using multiple variables In python, we can return multiple values from a function separated by a comma. To access these values in our main program, we have to use indexing: We use the values[0] syntax to access the first value in the list our calculate_data() function returns. Let’s write a function that returns the square of the argument passed. def square(x,y): This tutorial shows how multiple values can be returned from Python functions with multiple variables, objects, tuples, lists, and dictionaries. Values will be returned in the form of the tuple which can be assigned to a single variable or multiple variables through tuple unpacking. Python functions can return multiple values. We can use yield, in this case, to return multiple values one by one. Python offers several different ways of returning more than one variable from a function. Python functions can return both single and multiple values. Using a list or a tuple is best if the values you are returning have some kind of relationship.

These values should appear after your Python return statement. A Python return statement sends values from a function to a main program. This code works because the “return” statement turns our values into a tuple and returns a tuple list to our main program. In Python, you can return multiple values by simply return them separated by commas. Now we have to revise our function call and our print statement to support this new syntax: We return a dictionary back to our main program. Returning Multiple Values. As pointed out, in practice you'd use meaningful identifiers) We could also return a tuple data structure. Note that the return statement return x, y has the same result as return (x, y): the former actually packs x and y into a tuple under the hood!

From the above example, it looks like myFun() returns multiple values but actually tuple being created and returned. In our last example, we only returned two values to our main program. In addition to above all operations using the function, you can also return value to give back to the function. In describe(), you take advantage of Python’s ability to return multiple values in a single return statement by returning the mean, median, and mode of the sample at the same time. a list or a dictionary.

In Python, comma-separated values are considered tuples without parentheses, except where required by syntax. Option 3 : Using Tuple Option 1 : Using out keyword on parameters that will behave like return parameters. Meaning that if your function expects 2 arguments, you have to call the function with 2 arguments, not more, and not less. Option 1 : Using out keyword on parameters that will behave like return parameters. This guide discusses how to return multiple values to a main program using these two methods. Option 2 : Return class or structure which contains all the return values.

Get multiple values from function and total it. Example. If there is a chance two values you pass to your main program will be equal, avoid using a tuple. Built-in Types - Tuples — Python 3.7.4 documentation. Programmers can use this range() function to specify a particular range, to iterate the loop a specified number of times through that range. ; We can use the return statement inside a function only. 3. def square (x): return x* x. print (square (4)) Output. Our program returns the same response as earlier. Your function does not modify the global x and y. This made it convenient to use unpacking syntax (where you “unpack” values into multiple variables). We’re going to write a program that calculates the number of sales made at an electronics store. In this case the return values should be a comma-separated list of values and Python then constructs a tuple and returns this to the caller, e.g. These data types all let you store multiple values. Related: Lambda expressions in Python; The official documentation for function definition is: 4. The range function: As we understood how to use for loop in Python, now let us try to understand the range() function in for loop. See below for a simple example. To start, let’s define a Python array that contains a list of sales: Next, write a Python function that calculates the number of sales worth more than $500 and the average value of a purchase: Our function iterates over every sale in our list using a for loop. You need to return the values. 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.
