How does this code give me 17? (python)

j = 3

z = {}

z[2] = 1

z[7] = 3

z[5] = 2

for l in z:

j += l

print(j)


I don't understand where the 17 is coming from. I thought the square brackets were basically accessing the location (meaning the code would be like this "1, 2, 3." I even thought of individually adding 3 separately to all the numbers only for it to give me 15. Yeah, i've trying to understand this for 2 days lol.

Option c is correct. It tests whether the condition returned by the callback function holds for at least one item in array.

Every element in the array is put through the supplied test by the provided function using the every() method. It gives back a Boolean result. Until it locates the element for which callback function returns a false result, the every method calls the given callback function once for each element present in the array.

The every method immediately returns false if such an element is discovered. Every returns true if callback function does not return a truthy value for any of the items.

Only for array indexes with assigned values is callbackFn triggered. For empty slots in sparse arrays, it is not called.

The value of the element, the index of the element, and the Array object being traversed are passed as the three arguments to callbackFn.

The formula which is used to determine a company's customer retention rate is: 3. (The number of customers at the end of the period - the number of new customers acquired during the period)/ the number of customers at the start of the period x 100.

Customer retention rate can be defined as a measure of the number of customers that a business organization (company or firm) is able to successfully retain over a particular period of time and it is typically expressed as a percentage.

Mathematically, the customer retention rate of a business organization (company or firm) can be calculated by using this formula:

CRR = [(CE - CN)/CS] × 100

Where:

In conclusion, we can reasonably infer and logically deduce that the customer retention rate of a company simply refers to the percentage of existing customers that a business organization (company or firm) is able to retain after a given period of time.

Explanation:

Storage is one of the most important things to think about because, if you do not have enough storage then the update only hurts you. Then plus you cannot even get the update in most cases. How it changes the layout and how it changes the computers is important because it can be what makes a person hate the newest software or not. If the layout changes to something you do not agree with, then it can leave a person all mixed up. Lastly how it differs is important because, how it differs from the previous can be the reason why or why not you even need the update. The differences could be good or bad. But whenever updating software always look at the terms and conditions, what it changes, and what it takes to update the software.

When Lowell Thomas produced 4,000 units during his 40 hour workweek and his regular rate of pay is $0.12 per unit, the overtime pay is C. $19.50 per hour.

The number of hours a worker works in excess of what is required for a typical workweek is calculated as their overtime rate. Depending on how overtime is defined by the labor laws of each country and jurisdiction, this rate may have various implications in each.

The overtime premium or the overtime rate of pay are typical names for overtime compensation. The most common overtime rate is time and a half, which is 50% more than the employee's hourly pay. It means that you will receive 1.5 times your regular hourly rate for every hour of overtime worked.

The overtime will be calculated thus:

Multiply $0.12 4,000 = $480

Multiply regular pay, $0.04 1,000 = $40

Add: Bonus pay, $480 + $40 = $520,

Divide $520/40 = $13.00/hr

Multiply the rate: $13.00 * 1.5 = $19.50/hr.

Therefore, the overtime is $19.50.

Answer: python

i just did a test on this

Answer:

multiple things probably

Explanation:

Well the code is a bit confusing to read since the lack of indents but I'll try my best to interpret what you were trying to do.

By the looks of the exception you provided, it seems that the key "I" does not exist in your dictionary: "vowels_dict"

Same thing applies with the key "a" not existing in your dictionary: "consonants_dict"

This makes sense since by looking at your code since they obviously don't exist in their respective dictionaries.

I tried pasting the code into VisualStudio to get a better look at it and I tried to fix the indenting and to ensure I got it correct I provided what I indented below

"

for i in range(len(hawaiian_word)):

   if hawaiian_word[i] in valid_letters:

       for key in hawaiian_word:

           if hawaiian_word[i] in consonants_dict:

               pronunciation += consonants_dict[key]

   elif hawaiian_word[0][0] in vowels_dict:

       pronunciation += vowels_dict_capitalized[key]

   elif hawaiian_word[i] in vowels_dict:

       pronunciation += vowels_dict[key]

   elif hawaiian_word[i-2] in vowels_dict:

       pronunciation += vowels_no_hyphen_dict[key]

   if hawaiian_word[i] in invalid_letters:

       print('Invalid word, ' + hawaiian_word[i] + ' is not a valid hawaiian character.')

"

So there are a few issues I noticed, and I'm not exactly sure how to fix them since I'm not exactly sure what is supposed to be done.

1.

hawaiian_word[0][0] is redundant and likely not what you think.

The think with this line is it first returns the first letter of hawaiian_word which is now a one letter string, and now you get the first letter of this one letter string... which is the same string. You're likely trying to do something else but like I explained I'm not quite sure.

2.

for key in hawaiian_word:

   if hawaiian_word[i] in consonants_dict:

       pronunciation += consonants_dict[key]

So no runtime error should occur here since you're first checking if the key even exists, but I noticed your dictionary is defined as: "consonants_dict = {

'p':'p',

'k':'k',

'h':'h',

'l':'l',

'm':'m',

'n':'n',

'w':'w',

'aw':'w',

'iw':'v',

'ew':'v',

'uw':'w',

'ow':'w'

}

"

and you'll notice the last few keys have two letters, except your for loop is going through the word one letter at a time so these keys will never be used.

3. (probably the cause of your error)

the line in each elif statement you have some code along the lines of: pronunciation += dictionary[key]

except this key is only being defined in the for loop and and never changes. This key is actually just going to be the last letter of the word in each case assuming the first if condition is met the for loop runs and key is finally set to the last letter and never changes until it runs again but even then after it finishes it is set to the last letter. This word is unlikely to be in each dictionary. I'm assuming you meant to actually do:

elif hawaiian_word[0][0] in vowels_dict:

   key = hawaiian_word[0][0]

   pronunciation += vowels_dict_capitalized[key]

elif hawaiian_word[i] in vowels_dict:

   key = hawaiian_word[i]

   pronunciation += vowels_dict[key]

elif hawaiian_word[i-2] in vowels_dict:

   key = hawaiian_word[i-2]

   pronunciation += vowels_no_hyphen_dict[key]

because you're checking if the current letter you're on in word is in the dictionary but then you use something completely different?

Answer:  A. the network identifier

The words that would best complete this if-then statement is option B. Then you are a student.

A statement with a hypothesis and a conclusion is known as a conditional statement (also known as an If-Then Statement). "If this happens, then that will happen" is another approach to define a conditional statement. The initial clause, or "if," of a conditional statement is the hypothesis.

Note that the hypothesis is a prediction of what will transpire in your experiment. The terms "IF" and "THEN" are frequently used when writing the hypothesis. For instance, "I will fail the exam if I don't read." Your independent and dependent variables are reflected in the "if" and "then" statements.
