Answer:
The Solution to the given question can be defined as follows:
Explanation:
Please find the complete question in the attachment file.
In this case, the compiler will try to correct the model type by both the form we used when we try and call the method with both the appropriate form variable. It type of function. Consequently, unless the function in another file is specified, the compiler cannot locate the digital strategy. The point to note here is that only when this code is used, the template code shall be compiled.
The construct component will therefore be efficient so in this case, its connection stage would fail. An undefined connection to the feature <function name> can constitute a possible error in this case. It rules, therefore, address the construction project problem. Furthermore, the template function throughout the main program is generally recommended. It can be solved alternatively because parameters of a template like <function name><type> could be specified throughout the CPP file.
Answer:
There is a problem in the given code in the following statement:
Problem:
punctuation = r"[.?!,;:-']"
This produces the following error:
Error:
bad character range
Fix:
The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.
So the above statement becomes:
punctuation = r"[-.?!,;:']"
You can also do this:
punctuation = r"[.?!,;:'-]"
You can also change this statement as:
punctuation = r"[.?!,;:\-']"
Explanation:
The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2 which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false
import re #to use regular expressions
def compare_strings(string1, string2): #function compare_strings that takes two strings as argument and compares them
string1 = string1.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
string2 = string2.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
punctuation = r"[-.?!,;:']" #regular expression for punctuation characters
string1 = re.sub(punctuation, r"", string1) # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument
string2 = re.sub(punctuation, r"", string2) # same as above statement but works on string2 as 3rd argument
print('string1:',string1,'\nstring2:',string2) #prints both the strings separated with a new line
return string1 == string2 # compares strings and returns true if they matched else false
#function calls to test the working of the above function 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
