If a function in Python does not explicitly return a value using the return statement, it implicitly returns None by default. This means that when you call such a function, the result will be None, indicating that no value was returned. You can check this by assigning the function call to a variable and printing it, which will show None as the output.

Can a function in Python return more than one value?
Yes, a function in Python can return more than one value by using tuples, lists, or dictionaries. When multiple values are returned, they are typically packed into a tuple by default, which can then be unpacked by the caller. For example, a function can return two values like this: return value1, value2. The caller can capture these values using multiple assignment, such as a, b = my_function().
What statement returns a value from a function?
return
What module returns a value back to the part of the program that called it?
A function. You can have a function that returns but doesn't return a value with it.
1 Write a function called hello that given a persons name as a string returns the string hello followed by the name?
Here’s a simple Python function called hello that takes a person's name as a string and returns the greeting: def hello(name): return f"hello {name}" When you call hello("Alice"), it will return the string "hello Alice".
What is return in programming?
The return statement is used in functions to return control to the caller. If the function is declared non-void, the return statement also allows the programmer to return a value to the caller.
How do I use void in Python?
In Python, void is not a specific keyword or type like in some other programming languages. Instead, when you want to define a function that does not return a value, you simply define it without a return statement or use return without a value. Such a function is often referred to as returning None by default. For example: def my_function(): print("This function does not return anything.") Here, my_function() executes its code but does not return a value.

What is the function of plus sign?
The "plus sign" (+) is an operator that, by default, takes the left and right operands as parameters, and returns the sum of both operands as the return value.

What is meant by functions on python?
Python programming allows you to write your own programs. For example, to write a function named double that returns the number that you input, but doubled, we would write the following (where >>>> indicates a tab space) def double(x): >>>>x=x*2 >>>>return x
What statement causes a function to end and sends a value back to the part of the program that called the function?
The statement that causes a function to end and sends a value back to the calling part of the program is the return statement. When a return statement is executed, it terminates the function and can optionally pass a value back to the caller. If no value is specified, the function returns None in Python or equivalent in other languages. This allows the caller to receive the result of the function's computation.
What is different between a subroutine and function in vb.net?
Function returns a value but sub procedure do not return a value.
What part of a function definition specifies the data type of the value that the function returns?
The function header. The return value is written before the name of the function. This return type must match the type of the value returned in a return statement.
What is the default return type in C and C plus plus?
No. There is no default return type for functions, it must be explicitly specified in both the function declaration and in the definition. To specify no return value, return void. To return a variant type, return void* (pointer to void). Otherwise return the exact type.
