It is not considered good programming practice to declare all your variables globally. group of answer choices

1 answer:

3 0

The question statement is true that it is not considered good programming practice to declare all your variables globally in the program or code.

It is not considered a good programming practice to declare all the variables globally. Global variables are accessible and changeable by any function of the program. Thus, declaring all the variables globally creates a high chance of the data getting corrupted.

Any change in the values of the global variables, either is done by mistake or is the result of some other action, propagates to the whole program. In turn, that can lead to unexpected program behavior.

Consider a scenario where all data about bank balance is stored in a global variable. Storing this crucial data in a global variable makes a hin-ge to security of the data. As it can easily be accessed and modified by any function in the entire program.

Thus, it is highly recommended to use local variables with the exception of using a global variable only when there is an absolute need.

Answer:

The correct answer is:

Properties (D)

Explanation:

First of all, option D (Properties) is the option that makes the most sense in this scenario, because the other options: Copy, Delete, and Rename are unrelated commands to what is to be achieved.

Secondly and more practically, an add-in file may not load in excel, and most of the time it is blocked by default and has to be unblocked. The following steps are used:

1. close Excel if it is open

2. open the folder where the add-in file is located, right-click on the add-in file, and select "properties"

3. a display tray will appear, having the attributes: Read-only, Hidden, Advanced, and unblock. Click the checkbox against "unblock" and make sure it is checked.

4. click Apply and Click Ok

Voila, your add-in file is unblocked.

Write a Python program string_functions.py that defines several functions. Each function re-implements Python's built-in string

grigory [225]

Answer:

def my_compare(str1, str2):

mylist = sorted([str1, str2])

if str1 == str2:

return 0

elif str1 == mylist[0]:

return -1

elif str1 == mylist[1]:

return 1

def is_char_in(string, char):

if char in string:

return True

return False

def is_char_not_in(string, char):

if char not in string:

return True

return False

def my_count(string, char):

return string.count(char)

def my_endswith(string, char):

return string.endswith(char)

def my_find(string, char):

if char in string:

return string.index(char)

else:

return -1

def my_replace(string, char1, char2):

lst = [i for i in string]

print(lst)

for i, v in enumerate(lst):

if v==char1:

lst[i] = char2

return "".join(lst)

Explanation:

Above are defined functions similar to the string built-in functions in python. To use them, type in the function name and pass in the required arguments. Save the file name as "string_functions" with a ".py" file extension and use the functions in other files by importing all the function as "import string_functions" or import individual functions with "from string_function import 'function_name' ".

Identify a true statement about decision support systems (DSSs).

Zolol [24]

Answer:

a. facilitate improvements but do not necessarily cause them.

Explanation:

Decision Support Systems are interactive Information systems that assist decision makers in coming up with strategies that help the organisation achieve its goals .The model base of the DSS uses mathematical and statistical models to analyse information then it generates reports and suggest possible solutions that can be implemented .The system is capable of giving a specific solution and some even allow the decision makers to give input before suggesting the most applicable solution.The effectiveness of a DSS is equally as important as its efficiency .The DSS unlike the conventional decision-making process should be able to analyse information effectively and come up with solutions in the shortest possible time frame.
