In the string: This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression
Assign the regular expression to a variable named pattern
Using the sub() method from the re package substitute all occurrences of the 'pattern' with 'substitution'
Assign the outcome of the sub() method to a variable called replace_result
Output to the console replace_results
Answer:
Here is the Python program:
import re # module for regular expressions
search_string='''This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression''' #string to search for a regular expression
pattern = "regular.expression" #Assigns the regular expression to pattern
substitution="regular expression" #substitute all occurrences of pattern with regular expression string stored in substitution
replace_results = re.sub(pattern,substitution,search_string) # sub() method from the re package to substitute all occurrences of the pattern with substitution
print(replace_results) #Assigns the outcome of the sub() method to this variable
Explanation:
This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression
search_string='''This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression'''
The following statement assigns the regular expression to a variable named pattern .
pattern = "regular.expression"
The following statement is used to substitute the pattern (regular expression) in the search_string by replacing all occurrences of "regular expression" sub-string on search_string.
substitution="regular expression"
The following statement uses re.sub() method to replace all the occurrences of a pattern with another sub string ("regular expression"). This means in search_string, the sub strings like regular expression, regular-expression, regular:expression or regular&expression are replaced with string "regular expression". This result is stored in replace_results variable. Three arguments are passed to re.sub() method:
sub string to replace i.e. pattern
sub string to replace with i.e. substitution
The actual string i.e. search_string
replace_results = re.sub(pattern,substitution,search_string)
The following print statement displays the output of replace_results
print(replace_results)
The output of the above program is:
This is a string to search for a regular expression like regular expression or regular expression or regular expression or regular expression

Bill Schultz is thinking of starting a store that specializes in handmade cowboy boots. Bill is a longtime rancher in the town of Taos, New Mexico. Bill's reputation for honesty and integrity is well-known around town, and he is positive that his new store will be highly successful.
Before opening his store, Bill is curious about how his profit, revenue, and variable costs will change depending on the amount he charges for his boots. Bill would like you to perform the work required for this analysis and has given you the AYK12_Data.xlsx data file. Here are a few things to consider while you perform your analysis:_______.
• Current competitive prices for custom cowboy boots are between 5225 and $275 a pair.
• Variable costs will be either S100 or S150 a pair depending on the types of material Bill chooses
• to use.
• Fixed costs are $10,000 a month.
Data File: AYK12_Data.xlsx
Answer:
To calculate the profit of the month, the monthly cost should be extracted from the monthly generated revenue, while the revenue is the total sales of the store for the month.
Explanation:
In the excel file worksheet, the total number of shoes should be calculated. And a formula to calculate the revenue for the month should multiply the total shoes by the price of shoes per pair
The formula to calculate the profit is gotten from total sales minus the fixed cost.
The contains_acronym function checks the text for the presence of 2 or more characters or digits surrounded by parentheses, with at least the first character in uppercase (if it's a letter), returning True if the condition is met, or False otherwise. For example, "Instant messaging (IM) is a set of communication technologies used for text-based communication" should return True since (IM) satisfies the match conditions." Fill in the regular expression in this function:
Answer:
Following are the code to this question:
import re#import package regular expression
def contains_acronym(val): #defining a method contains_acronymn that accepts text value in parameter
match= r"\([A-Z1-9][a-zA-Z1-9]*\)"#defining match variable that uses upper case, number, and lower case value
r= re.search(match, val)#defining r varaible that uses search method to search values
return r!= None #use return keyword
val="Instant messaging (IM) is a set of communication technologies used for text-based communication"

How do the following technologie help you in your quest to become a digital citizen: kiosks, enterprise computing, natural language processing, robotics, and virtual reality?
Answer:
kiosks
Explanation:
It is generally believed that a digital citizen refers to a person who can skillfully utilize information technology such as accessing the internet using computers, or via tablets and mobile phones, etc.
Kiosks (digital kiosks) are often used to market brands and products to consumers instead of having in-person interaction. Interestingly, since almost everyone today goes shopping, consumers who may have held back from using digital services are now introduced to a new way of shopping, thus they become digital citizens sooner or later.
Enterprise computing, natural language processing, robotics, and virtual reality are vital for an individual to become a digital citizen.
Enterprise computing simply means a business-oriented technology that's vital to the operations of a company. It's part of the critical infrastructure of a company.
Robotics is the design, construction, and the use of robots. It's used for assisting human beings to perform different operations.
Virtual reality refers to a stimulated experience that appears to make objects and scenes real. It should be noted that robotics, virtual reality, natural processing language, etc are vital for an individual to become a digital citizen.

Describe how catching exceptions can help with file errors. Write three Python examples that actually generate file errors on your computer and catch the errors with try: except: blocks. Include the code and output for each example in your post. Describe how you might deal with each error if you were writing a large production program. These descriptions should be general ideas in English, not actual Python code.
Answer:
Three python errors are; import error, value error, and key error.
Explanation:
Errors occur in all programming languages and just like every other language, python has error handling techniques like the try and except and also the raise keyword.
A value error occurs when an output of a variable or expression gives an unexpected value. Import error results from importing a module from an unknown source while a key error is from a wrong input keypress.
Catching these errors and raising an error gives more control and continuity of the source code.
Answer:
Catching exceptions helps a programmer to resolve raised issues at runtime instead of deliberately closing their program.
There are a lot of types of file errors. e.g. hadware/os errors, name errors,
operation errors, data errors.
Explanation:the function try will provide a testing of your code validating if it is correct, it will continue running. and adding the function except, it will print the error.
Dealing with the error depends on what you like the program to do and how you want to identify the errors so you can work on them.
