Question

Transcribed Image Text:**Understanding Variable Scope in Python**
When a variable is created within a Python function, its scope starts from its creation and exists until _____.
**Select one:**
- a. The entire program ends.
- b. The function places the variable in the trash.
- c. The function is no longer going to be called again.
- d. The function returns.
**Explanation:**
In Python, the scope of a variable refers to the region of the code where the variable is recognized. When a variable is created inside a function, it is known as a local variable. This local variable's scope starts from its creation within the function and lasts until the function returns, which means the end of the function's execution. After the function returns, the variable is no longer accessible, and its allocated memory can be reclaimed by the system. It is important for beginners to understand this concept to avoid errors related to variable scope and memory management in their code.

Thanks.arrow_forwardCode is in Pythonarrow_forwardWrite a program that calculates the balance of a checking account at the end of a three- month period. It should ask the user for the starting balance. Then a loop (for loop is recommended) should iterate once for every month in the period, performing the followi 1. Ask the user for the total amount deposited into the account during that month. Do n accept negative number. This deposit should be added to the current balance to make current balance is up to date. 2. Ask the user for the total amount withdrawn from the account during that month. Do accept negative amount or amount greater than the current balance. The withdrawal amount should be subtracted from current balance, so current balance is up to date. 3. Update the total deposit. 4. Update the total withdrawal After the last iteration, the program should display the following information: 1. starting balance at the beginning of the three-month 2. total deposits/withdrawals made during the three-month period 3. final balance…arrow_forward

Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: Nonearrow_forward
