The fourth choice is correct.
Answer:
Following are the correct code to this question:
short_names=['Gus','Bob','Zoe']#defining a list short_names that holds string value
print (short_names[0])#print list first element value
print (short_names[1])#print list second element value
print (short_names[2])#print list third element value
Output:
Gus
Bob
Zoe
Explanation:
- In the above python program code, a list "short_names" list is declared, that holds three variable that is "Gus, Bob, and Zoe".
- In the next step, the print method is used that prints list element value.
- In this program, we use the list, which is similar to an array, and both elements index value starting from the 0, that's why in this code we print "0,1, and 2" element value.
a. stateTaxRate - A good variable name because it represents what it holds, the state sales tax rate, without being too wordy. Also correctly capitalized in camelcase.
b. txRt - A bad variable name because while short and simple, it is too hard to understand what the variable represents.
c. t - A very bad variable name if you plan on using the variable often. Far too short and you will forget what it represents and is needed for.
d. stateSalesTaxRateValue - A bad variable name because it is just too wordy. Cutting it down to A's variable name is much more reasonable
e. state tax rate - A bad variable name and probably invalid because it has spaces in the name.
f. taxRate - A good variable name if there are no other tax calculations other than state tax rate. Otherwise you would confuse state vs local tax rate or something, making it a bad variable name.
g. 1TaxRate - A bad variable name because the number 1 has no reason being in the variable name. It doesn't add anything to the name.
h. moneyCharged - A bad variable name because it is not specific enough in explaining why the money is being charged and what for.
