Instructions

Write a python code file named read$\_$file$\_$exercise.py

Your code should do the following:

ask the user for the name of a text file $($a shopping list$)$

read the data in the text file $($lines of text$)$

print the shopping list data

When printing the shopping list, there should be no blank lines

between items to be bought. You can use the rstrip$()$ function

to remove newline characters from the lines read from the data file.

Example

file name? shopping$\_$list$\_1.$txt

Shopping List

bananas

cat food

paper towels

brownie mix

carrots

brussel sprouts

catfish fillets

Error Handling

If the file asked for by the user does not exist,

the program should not crash. It should instead

print an error message as shown below.

file name? shopping$\_$list$\_3.$txt

ERROR: file shopping$\_$list$\_3.$txt could not be read

One way to handle a file opening error is to use try$/$except$.$

try:

file code goes here

open file

read file

close file

except:

error message code goes here
