Question

I have a python question

Answer 1

The trustees of a small college are considering voting a pay raise for their faculty members. They want to grant a 7 percent raise for those earning more than $50,000.00, a 4 percent raise for those earning more than $60,000.00 and 5.5 percent raise for all others. However before doing so, they want to know how much this will cost. Write a program that will print the pay raise for each faculty member, the total amount of the raises, and the average of the raises. Also, print the total faculty payroll before and after the raise. Use the end of file as a sentinel value. The input data is available in program7.txt on the I: drive. Do NOT use a logical operator in the program

So far, all I have is this, and I am stuck on how to finish it.

program7.txt:

52500.00 64029.50 56000.00 50001.00
65500.00 42800.00 45000.50 68900.00
60000.00 59999.94 54120.25 64100.00
44000.50 80100.20 90000.00 41000.00
60500.50 72000.00 50000.01 50000.00
80001.75 60001.00

Program:

def main():

inFile = open('program7.txt', 'r')

lineRead = inFile.readline()
while lineRead != '':
words = lineRead.split()
for word in words:
num = float(word)
print(format(num, '.2f'))
percentRaise()
lineRead = inFile.readline()

# Close the file.
inFile.close()

def percentRaise():
while lineRead <= 50000:
salary = word * .55
newsal = word + salary
print("New Salary = ", newsal)

# Call the main function.
main()

Answer 2

First of all I would like you to show you a trick to enter code here in OS so that it can be copied without having to put in all end of line and idents back in again:
enter three \` at the ~ key (you have to enter a space after each to have it turn up). This ``` makes a new block start. Start it at a new line, then enter your code and then at a new line enter three ``` again
```
def percentRaise():
while lineRead <= 50000:
salary = word * .55
newsal = word + salary
print("New Salary = ", newsal)

# Call the main
function. main()
```

That way you can copy the code without loosing end of lines and idents

Answer 3

So, the program may not make use of any logical operators: and, or, not

Answer 4

I think, your function def percentRaise(): lacks a return statement

Answer 5

and you need to send the relevant variables to the functions you use

Answer 6

@immanuelv
In def percentRaise() you use use
```
while lineRead <= 50000:
```
You probably mean 'word'

Answer 7

You also use
```
salary = word * .55
```
but that is 55%, you probably mean 0.055

Answer 8

Itś best to break up the assignment into chunks that you can solve

The trustees of a small college are considering voting a pay raise for their faculty members. They want to grant

a 7 percent raise for those earning more than $50,000.00,
a 4 percent raise for those earning more than $60,000.00 and
a 5.5 percent raise for all others.

in pseudocode that could be more like

if salary > 60 000 then raise=0.07 # remember that 7% is 0.07
elif salary > 50 000 then raise=0.04
# this is valid for all salaries > 50 000 and smaller than 60 000
else raise=0.055
```
if salary > 60000::
raise=0.07
elif salary > 50 000: # 50 000< salary < 60 000
raise=0.04
else:
raise=0.055
```

Answer 9

However before doing so, they want to know how much this will cost.
Write a program that will

print the pay raise for each faculty member pay
raise= salary*raise print pay raise

Python 2.7
```
pay_raise = salary*raise
print salary, pay_raise
```
Python 3 something like ?
```
pay_raise = salary*raise
print(format(salary, '.2f'), format(pay_raise, '.2f'),
```

Answer 10

the total amount of the raises, and the average of the raises.
total amount of the pay raises = sum over all pay raises
average pay raise = sum over all pay raises/nr of salaries

So after each calculation of the raise, you need to keep track of the totoal
```
total_pay_raise += pay_raise
```
You also need to count the number of salaries:
so for instanceafter
words = lineRead.split()
```
nr_of_sal += len(words)
```
Now
average pay raise = sum over all pay raises/nr of salaries
could be coded as
```
averrage_pay_rase = total_pay_raise / nr_of_sal
```


```
average_pay_raise = total_pay_raise

Answer 11

forget the last line, that is some kind of glitch

Answer 12

Also,
print the total faculty payroll before and after the raise.

total faculty payroll before the raise = sum over all salaries
total faculty payroll after the raise =
total faculty payroll + total amount of the raises

so we also need to sum over all salaries that are read from the file
```
total_sal_before += salary
total_sal_after = total_sal_before + total_pay_raise
```

Answer 13

Now you've got all the ingredients from which you can improve your code

Answer 14

in my code snippets, you cannot use the word 'raise', because it is a keyword in Python

Answer 15

Your overall structure is quite well
You do need to pass each salary to the function
and you need to return the pay_raise back to your main() function
and you need to pass that return value to the pay_raise where you call it

```
pay_raise = percentRaise(salary) # you used 'num', where I use 'salary'
```

Answer 16

thank you so much

Answer 17

btw @abtster i did it almost the way you said it

midSalary = 50000
maxSalary = 60000


def main():

inFile = open('program7.txt', 'r')

lineRead = inFile.readline()
while lineRead != '':
words = lineRead.split()
total = 0.0
ntotal = 0.0
for word in words:
num = float(word)
total += num
print("\nFaculty Member:$", format(num, '.2f'), sep ="")
if num >= maxSalary:
prcntRaise = .04
salRaise = num * prcntRaise
newSal = num + salRaise
print("Your pay raise percent will be:", format(prcntRaise*100, ".1f")+'%')
print("Your pay raise will be:$", format(salRaise, ',.2f'), sep ="")
print("Your new salary will be:", format(newSal, ',.2f'), sep = "")
ntotal += newSal
elif num >= midSalary:
prcntRaise = .07
salRaise = num * prcntRaise
newSal = num + salRaise
print("Your pay raise percent will be:", format(prcntRaise*100, ".1f")+'%')
print("Your pay raise will be:", format(salRaise, ',.2f'), sep ="")
print("Your new salary will be:", format(newSal, ',.2f'), sep ="")
ntotal += newSal

else:
prcntRaise = .055
salRaise = num * prcntRaise
newSal = num + salRaise
salAvg = num / newSal
print("Your pay raise percent will be:", format(prcntRaise*100 ,".1f")+'%')
print("Your pay raise will be:", format(salRaise, ',.2f'), sep ="")
print("Your new salary will be:", format(newSal, ',.2f'), sep ="")
ntotal += newSal


lineRead = inFile.readline()
print("\nTotal Faculty payroll:$", format(total , ",.2f"),sep ="")
print("The New Faculty payroll:$", format(ntotal , ",.2f"),sep ="")



# Close the file.
inFile.close()

Answer 18

Does it work ok?

Answer 19

I think your initialisations have to be befrore the while loop
```
total = 0.0
ntotal = 0.0

while lineRead != '':
words = lineRead.split()
```

Answer 22

absolutely

Answer 23

after every 4 payroll calculation it gives me total salary

Answer 24

I see

Answer 25

i think the part you said about "initialisations have to be befrore the while loop" fixed that problem

Answer 26

nvm

Answer 27

Do not forget the average raise part

Write a program that will print

print the total amount of the raises,
print the average of the raises.

Answer 28

this is my new code and its solution
i have not put average raise yet

midSalary = 50000
maxSalary = 60000


def main():

inFile = open('program7.txt', 'r')

lineRead = inFile.readline()
total = 0.0
ntotal = 0.0

words = lineRead.split()
for word in words:
num = float(word)
total += num
print("\nFaculty Member:$", format(num, '.2f'), sep ="")
if num >= maxSalary:
prcntRaise = .04
salRaise = num * prcntRaise
newSal = num + salRaise
print("Your pay raise percent will be:", format(prcntRaise*100, ".1f")+'%')
print("Your pay raise will be:$", format(salRaise, ',.2f'), sep ="")
print("Your new salary will be:", format(newSal, ',.2f'), sep = "")
ntotal += newSal
elif num >= midSalary:
prcntRaise = .07
salRaise = num * prcntRaise
newSal = num + salRaise
print("Your pay raise percent will be:", format(prcntRaise*100, ".1f")+'%')
print("Your pay raise will be:", format(salRaise, ',.2f'), sep ="")
print("Your new salary will be:", format(newSal, ',.2f'), sep ="")
ntotal += newSal

else:
prcntRaise = .055
salRaise = num * prcntRaise
newSal = num + salRaise
salAvg = num / newSal
print("Your pay raise percent will be:", format(prcntRaise*100 ,".1f")+'%')
print("Your pay raise will be:", format(salRaise, ',.2f'), sep ="")

Answer 29

You also need

to print the total amount of the raises, and
to print the average of the raises.

Answer 30

thats the part im having trouble on right now... :(

Answer 31

sum over all the pay_rayses

and a counter that adds 1 after the you assign

calculate and print at the end of your program

Answer 32

count =0
while lineRead != '':
words = lineRead.split()
for word in words:
num = float(word)
count += 1
total += num
print("\nFaculty Member:$", format(num, '.2f'), sep ="")

Answer 33

would it be something close to this?

Answer 34

yes, that is right

Answer 35

do i calculate and print it after

inFile.close() ?

Answer 36

I would, yes

Answer 37

omg that fix it :D
you're the best man!!!!!

Answer 38

Great that you've got it

Answer 39

well..... i made a small mistake :(

Answer 40

i tried to do
nr_of_sal += len(words) in my program as

for word in words:
num = float(word)
total += num
count += 1
averagePayRaise = total / numOfSal
print("\nFaculty Member:$", format(num, '.2f'), sep ="")

and it gave me an error

Answer 41

total is the sum of all salaries, not of the pay raise
and
numOfSal
should be count

and count needs to be set to zero (initialised) at the top of your main() function

Answer 42

this was my final code :D and it works neatly

midSalary = 50000
maxSalary = 60000


def main():

inFile = open('program7.txt', 'r')

lineRead = inFile.readline()
total = 0.0
ntotal = 0.0
count = 0
while lineRead != '':

for word in words:
num = float(word)
total += num
count += 1

print("\nFaculty Member # ",count, ": $" , format(num, '.2f'), sep ="")
if num >= maxSalary:
prcntRaise = .04
salRaise = num * prcntRaise
newSal = num + salRaise
print("Pay Raise Percent :", format(prcntRaise*100, ".1f")+'%')

print("The New Total Faculty payroll : $", format(ntotal , ",.2f"),sep ="")
print("Average Pay Raise : $", format(averagePayRaise, ",.2f"), sep ="")


# Call the main function.
main()

// thank you so much man. I could've not finished it without you

Answer 43

Nice work,
Your intial overall structure was really good

Answer 44

thank you @abtster
