The compare_strings function is supposed to compare just the alphanumeric content of two strings, ignoring upper vs lower case a

nd punctuation. But something is not working. Fill in the code to try to find the problems, then fix the problems.
import re
def compare_strings(string1, string2):
#Convert both strings to lowercase
#and remove leading and trailing blanks
string1 = string1.lower().strip()
string2 = string2.lower().strip()

#Ignore punctuation
punctuation = r"[.?!,;:-']"
string1 = re.sub(punctuation, r"", string1)
string2 = re.sub(punctuation, r"", string2)

#DEBUG CODE GOES HERE
print(___)

return string1 == string2

print(compare_strings("Have a Great Day!", "Have a great day?")) # True
print(compare_strings("It's raining again.", "its raining, again")) # True
print(compare_strings("Learn to count: 1, 2, 3.", "Learn to count: one, two, three.")) # False
print(compare_strings("They found some body.", "They found somebody.")) # False

Answer:

The issue within the provided code is located in this part:

Problem:

punctuation = r"[.?!,;:-']"

This results in the following error:

Error:

bad character range

Solution:

The hyphen - needs to be positioned at either the beginning or end of the character list. In this context, the hyphen acts to specify a range of characters. Another option is to escape the hyphen - using a backslash \.

Thus, the corrected statement would be:

punctuation = r"[-.?!,;:']"  

Alternatively, you can write it as:

punctuation = r"[.?!,;:'-]"  

Additionally, you might modify it like this:

punctuation = r"[.?!,;:\-']"

Explanation:

The complete program is outlined as follows. I have inserted a print statement print('string1:',string1,'\nstring2:',string2) that outputs string1 and string2 , followed by return string1 == string2, which will return either true or false. However, you can omit the print('string1:',string1,'\nstring2:',string2) line and the result will still show true or false

import re  #to employ regular expressions

def compare_strings(string1, string2):  #defining compare_strings function that takes in two strings and checks them

   string1 = string1.lower().strip()  # converts string1 to lowercase using lower() method and gets rid of leading and trailing spaces

   string2 = string2.lower().strip()  # similarly converts string2 to lowercase and removes spaces

   punctuation = r"[-.?!,;:']"  #regular expression for punctuation marks

   string1 = re.sub(punctuation, r"", string1)  # applies RE pattern for punctuation in string1

   string2 = re.sub(punctuation, r"", string2)  # same action as above for string2

   print('string1:',string1,'\nstring2:',string2)  #displays both strings, separated by a new line

   return string1 == string2  #compares the strings and returns true if they match, otherwise false

#function calls to validate the functionality of compare_strings

print(compare_strings("Have a Great Day!","Have a great day?")) # True

print(compare_strings("It's raining again.","its raining, again")) # True

print(compare_strings("Learn to count: 1, 2, 3.","Learn to count: one, two, three.")) # False

print(compare_strings("They found some body.","They found somebody.")) # False

A screenshot of the program and its output is provided.

I'd argue that D is the correct option; Target based budgeting.


Target based budgeting centers on achieving objectives and competing alternatives. This budgeting approach uses pricing as a strategic tool to influence sales outcomes. It involves market research to determine the precise selling price of a product.
