Can you return more than one value in Python?
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 do you return more than one value?
We can return more than one values from a function by using the method called “call by address”, or “call by reference”. In the invoker function, we will use two variables to store the results, and the function will take pointer type data. So we have to pass the address of the data.
Can we return more than one value from a function?
If we want the function to return multiple values of same data types, we could return the pointer to array of that data types. We can also make the function return multiple values by using the arguments of the function.
How do you return 3 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 Kwargs in Python?

How many objects can a Python function return?
A function can only return a single object. If more than one variable is part of a return statement python will automatically pack them into a tuple.
What is the difference between return 0 and return 1?
return 0 in the main function means that the program executed successfully. return 1 in the main function means that the program does not execute successfully and there is some error. return 0 means that the user-defined function is returning false. return 1 means that the user-defined function is returning true.
What is main return?
The return value for main is used to indicate how the program exited. If the program execution was normal, a 0 return value is used. Abnormal termination(errors, invalid inputs, segmentation faults, etc.) is usually terminated by a non-zero return.

Can you have two functions in Python?
The exercise is to create two functions and then call on the first function if a number is divisible by 3. This is quite simple to accomplish. When you are creating these functions remember the OOP(Object-Orientated Programming) is the reason why this works so well in python.
What is Kwargs get in Python?

kwargs. get() retrieves a keyword argument passed to a function. The first argument is the keyword and the second is the default value if there was no argument provided for the keyword.
What does Argparse return?
Later, calling parse_args() will return an object with two attributes, integers and accumulate . The integers attribute will be a list of one or more ints, and the accumulate attribute will be either the sum() function, if –sum was specified at the command line, or the max() function if it was not.
What does Argparse ArgumentParser () do?
ArgumentParser() initializes the parser so that you can start to add custom arguments. To add your arguments, use parser. add_argument() . Some important parameters to note for this method are name , type , and required .
What does return 2 mean?
