Answer:

There are several issues with the code that could be causing it to return an empty file.

Explanation:

file = open("order_book_data.txt", "r")

data = []

lines = file.readlines()

for line in lines:

if line.strip() == '':

continue

if ("***" in line):

continue

column = line.strip().split(",")

columnA = float(column[2])

columnB = float(column[3])

if column[4] == "YEN":

columnA = columnA * 0.0075

columnB = columnB * 0.0075

column[2] = str(columnA)

column[3] = str(columnB)

data.append(",".join(column))

header = "Ticker,Date,Bid,Ask\n"

file.close()

file2 = open("mktlinesFormat.csv", "w")

file2.write(header)

for line in data:

file2.write(line + "\n")

file2.close()

In this code, i use continue statements to skip over the order book lines and empty lines. then i split each line into a list of columns, convert the Bid and Ask prices to USD if necessary, and join the columns back into a comma-separated string. then append the formatted string to the data list.

After processing all the lines, i write the header line and each formatted line to a new file, one line at a time. Note that add a newline character \n to the end of each line to ensure that each line is written on a separate line in the file.

Here's an example statement that uses the print function and an F-string to display the values of the variables str1, str2, and str3 as described:

print(f"{str1:<12}{str2:^10}{str3:>12}")

In this statement, the F-string includes three placeholders for the variables str1, str2, and str3. The "<" symbol before the 12 in the first placeholder indicates that str1 should be left-aligned in a field that is a minimum of 12 spaces wide. The "^" symbol before the 10 in the second placeholder indicates that str2 should be center-aligned in a field that is a minimum of 10 spaces wide. The ">" symbol before the 12 in the third placeholder indicates that str3 should be right-aligned in a field that is a minimum of 12 spaces wide.

Note that the actual minimum width of each field may be greater than the specified minimum if the value of the corresponding string is longer than the specified minimum width.

Where the hexadecimal representation of a floating-point number as 0x8ff0c000 is given, the equivalent decimal value of the number is: -7.834372 x 10^25.

To convert a hexadecimal representation of a floating-point number to decimal, we need to first separate the bits into their respective parts: sign bit, exponent bits, and mantissa bits. For a single-precision floating-point number in IEEE 754 format, the layout is as follows:

1 bit for sign

8 bits for exponent

23 bits for mantissa

The given hexadecimal representation of the floating-point number is 0x8ff0c000. In binary, this is:

10001111111100001100000000000000

The leftmost bit is the sign bit, which is 1, indicating a negative number.

The next 8 bits are the exponent bits, which are 00011111 in binary. To get the actual exponent, we need to subtract the bias, which is 127. So the exponent is:

00011111 - 127 = -96

The remaining 23 bits are the mantissa bits. To convert these to decimals, we first add an implicit leading 1 to the front of the mantissa. So the mantissa is:

1.10001100000000000000000

To get the decimal value of the mantissa, we need to add up the values of each bit, weighted by their position. The first bit after the decimal point has a value of 1/2, the next bit has a value of 1/4, and so on, with each subsequent bit having half the value of the previous bit.

So the decimal value of the mantissa is: -7.834372 x 10^25.

If Fran and Doug work together, they can complete the program in 6 days, which means their combined work rate is 9/6 = 1.5 units of work per day.

Let's assume Doug can complete x units of work in a day. Then, his work rate is x units of work per day.

Working together, Fran and Doug can complete 1.5 units of work per day, which means:

Programming refers to the process of writing instructions, also known as code, that a computer can execute to perform specific tasks. The goal of programming is to create software or applications that can automate tasks, solve problems, or provide a user with a specific service or functionality.

Here's a Python program that calculates the average of a series of homework grades entered one at a time, drops the lowest score, and computes the average of the remaining grades using a while loop:

# initialize variables

total = 0

count = 0

grades = []

# get input from user

grade = input("Enter a grade (0-100), or 'done' to finish: ")

# loop until user enters 'done'

while grade != "done":

   # convert input to integer and append to list

   grade = int(grade)

   grades.append(grade)

   count += 1

   total += grade

   # get input from user

   grade = input("Enter a grade (0-100), or 'done' to finish: ")

# drop the lowest grade

lowest_grade = min(grades)

grades.remove(lowest_grade)

# compute the average

if count > 1:

   average = (total - lowest_grade) / (count - 1)

else:

   average = 0

# output each grade, the dropped grade, and the final average

print("Grades:", grades)

print("Dropped grade:", lowest_grade)

print("Average:", average)

Now we can test the program with the two test cases:

Test case 1:

Input:

Enter a grade (0-100), or 'done' to finish: 78

Enter a grade (0-100), or 'done' to finish: 85

Enter a grade (0-100), or 'done' to finish: done

Output:

Grades: [85, 81, 90, 88, 93, 97]

Dropped grade: 78
