To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).
Option A is the correct answer for the above question.
Explanation:
The computer is a system that processes the data to produce information. For any computer system when the data is processed then it will form the information.
The user gives some instruction to process that can also be called the program. Then the computer takes the instruction and processes the data on behalf of the instruction and for the information because in any system when data is processed it can form the information.
The above question says that the computer follows the instruction to process the data to produce the information which is correct as described above. Hence True is the correct answer to the above question.
Header files serve two purposes. System header files declare the interfaces to parts of the operating system. You include them in your program to supply the definitions and declarations you need to invoke system calls and libraries.
The item that you would most likely to keep in a database is a Payroll record. Payroll records are numbers and inputs/outputs of employees of a certain company. Numbers are easier to manipulate and easier to manage than statements, letters and addresses that are basically letters.
