Is a variable that receives an argument that is passed into a function?
A parameter variable is a variable local to the function which receives the argument. That is to say, the argument’s value is copied into the parameter variable.
What are the variables that receive pieces of data in a function called?
A parameter is a special kind of variable used in a function to refer to one of the pieces of data provided as input to the function. These pieces of data are the values of the arguments with which the function is going to be called/invoked.
What function reads a piece of data that has been entered at the keyboard and returns that piece of data as a string back to the program?
Answer: The input function reads a piece of data that has been entered at the keyboard and returns that piece of data, as a string, back to the program.
What type of value is returned by the functions random and uniform?
Calculate the Price
| What is a GROUP OF STATEMENTS that exists within a program for the purpose of performing a specific task? | Function |
|---|---|
| What type of value is returned by the functions RANDOM AND UNIFORM? | Float |
When an argument is passed by value?
Pass by value means that a copy of the actual parameter’s value is made in memory, i.e. the caller and callee have two independent variables with the same value. If the callee modifies the parameter value, the effect is not visible to the caller.
What’s the difference between a parameter and an argument?
A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method’s parameters. Parameter is variable in the declaration of function. Argument is the actual value of this variable that gets passed to function.
What are the two main types of functions?
What are the two main types of functions? Explanation: Built-in functions and user defined ones. The built-in functions are part of the Python language.
What are the parts of a function?
We will see many ways to think about functions, but there are always three main parts:
- The input.
- The relationship.
- The output.
How do you determine which is the last line of a function?
How do you determine which is the last line of a function? a) The first return statement is the last line of a function.
What does the following statement mean num1 num2 Get_num ()?
What does the following statement mean? num1, num2 = get_num() The function get_num() is expected to return a value each for num1 and num2. The randrange function returns a randomly selected value from a specific sequence of numbers.

What type of file access jumps directly to any piece of data in a file without reading the data that came before it?
When working with a sequential access file, you can jump directly to any piece of data in the file without reading the data that comes before it. When you open a file that file already exists on the disk using the “w” mode, the contents of the existing file will be erased.
What does the following statement do import random?
Explanation: The command import random is used to import the random module, which enables us to use the functions which are present in the random library. 2. The output of the following Python code is either 1 or 2.
What is the first negative index in a list?
2 Answers. Negative numbers mean that you count from the right instead of the left. So, list[-1] refers to the last element, list[-2] is the second-last, and so on. List indexes of -x mean the xth item from the end of the list, so n[-1] means the last item in the list n.
What will be the output after the following code is executed and the user enters 75 and 0?
what will be the output after the following code is executed and the user enters 75 and 0 at the first two prompts? nothing; there is no print statement to display average.
