Lists are different from tuples since they are mutable. If you want to get multiple values at a time, use something like x, y = func()[2:4]. 1) Using Object. This is the default property of python to return multiple values/variables which is not available in many other programming languages like C++ or Java. Since the only data type in J is array (this is an oversimplification, from some perspectives - but those issues are out of scope for this task), this is sort of like asking how to return only one value in another language. Here’s another example. Like java, you can return multiple values in python, There are four ways to do this.

A tuple is always preferable to a list when mutability is not a requirement. A list may include strings, integers, and items. A class (in C, a struct) can be formed to hold several attributes and return a class object: Using Python 3.7’s data classes, this is how you can return a class with automatically added unique methods, typing, and other useful tools: See the official documentation for further clarity on data classes. The most crucial point is that you need to learn concepts and develop your programming skills. How to return multiple values in Python function. It can be used to return multiple values to a main program. In Python, we can return multiple values from a function. Note that, to return multiple values, you just need to write them in a comma-separated list in … We can use yield, in this case, to return multiple values one by one. Return Values.
