Question

Part A: CHALLENGE ACTIVITY 7.6.2: For loop. Printing a list.

Write the Python code to accomplish the following tasks:

• Input a string from the keyboard that represents three or more stock prices separated by spaces

o Example: ‘34.62 76.30 85.05’

• Convert the string into a Python list of floats

• Print each price in the list on a separate line with a dollar sign ($) as the first character on each line

• Print the output such that the decimal points are aligned vertically even if the user enters values such as ‘1.23 23.45 345.56’

Part B: Based on CHALLENGE ACTIVITY 7.7.3: Hourly temperature reporting.

Write the Python code to perform the following tasks:

• Use the same list of floats from part A

• Take as input from the user a two-character string from the keyboard to use as a separator during printing

o Example: user should enter something like ‘->’, ‘=>’, ‘<>’

• Write a loop that will print all elements of the list to the same line on the display

o Each element should be separated from other elements by the user-chosen separator characters including a space on each side. The space and separator should not be printed after the last number.

Example output (using input 1.23 23.45 345.56 and ->):

Enter three or more stock prices separated by spaces: 1.23 23.45 345.56

$ 1.23

$ 23.45

$ 345.56

Enter a two-character separator: -> 1.23 -> 23.45 -> 345.56

Answer 1

SOLUTION-

1)

CODE-

s = input('Enter stock prices separated by spaces: ')
prices = [float(v) for v in s.split()]  
for p in prices:
   print('${:7.2f}'.format(p))

OUTPUT-

2)

CODE-

string = input('Enter three or more stock prices seperateed by spaces : ')
lst =string.split()

for i in lst:
    print('$',i)
  
sep=input('Enter a two character sepearator: ')
for i in range(len(lst)):
    print(lst[i], end=' ')
    if i != len(lst) - 1:
        print(sep, end=' ')

OUTPUT-
