Question

Write an expression to print each price in stock_prices. Sample output with inputs: 34.62 76.30 85.05

Answer 1

Answer:

Here is the Python program:

stock_prices = input().split() #to take input and splits it into a list

for price in stock_prices: #iterates through stock_prices

   print("$",price) #prints each value of stock_prices with a dollar sign

Explanation:

The program is well explained in the attached comments. I will explain the logic of the program with the help of an example:

Suppose the user enters the following input as stock_prices values

34.62 76.30 85.05

input() method is used to take input from user

split() method is used to split or break this input string and returns a list of strings as:

['34.62', '76.30', '85.05']    

Now the statement for price in stock_prices: iterates through each item of the list and print("$",price) prints each value of list with a dollar sign on the output screen as:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05    

Answer 2

The program inputs the dollar sign to each of the user inputted stick prices. The program written in python 3 goes thus ;

t = input('Enter values : ')

#takes inputs from user for stock prices

stock_prices = [eval(x) for x in t.split()]

#splits the values based on whitespace assigns to a list variable using list comprehension

for price in stock_prices :

#iterates through the prices in the list

print("$", price)

#place the dollar sign behind each value and display
