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

Korolek [52]

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

The screenshot of the program along with its output is attached.

When mehtod X calls method Y , method Y called methhod Z, and method Z calles method X, this is called

taurus [48]

Answer:

D.Indirect Recursion.

Explanation:

Indirect recursion is when a method calls other method which calls the original method again.

For example:-

public static int mthd1( int n)

{

if (n == 0)

return 0;

else

return (mthd2(n-1));

}

public static int mthd2(int n2)

{ return mthd1( n2-1); }

This is an example of indirect recursion.Where mthd1 calls mthd 2 and mthd 2 calls mthd 1 again.

Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will rea

irinina [24]

Answer:

Check the explanation

Explanation:

Executable Code:

def all_permutations(permList, nameList):

# Define the function to create a list

# of all the permutations.

def createPermutationsList(nameList):

# Compute and store the length of the list.

n = len(nameList)

# Return an empty list if the size is 0.

if n == 0:

return []

# Return the element if the size is 1.

if n == 1:

return [nameList]

# Create an empty list to store the permutations.

permList = []

# Start the loop to traverse the list.

for i in range(n):

# Store the first element of the current list.

first = nameList[i]

# Compute the store the remaining list.

remaining = nameList[:i] + nameList[i+1:]

# Start the loop and call the function recursively

# with the remaining list.

for perm in createPermutationsList(remaining):

# Append the element in the permutation list.

permList.append([first] + perm)

# Return the permutation list.

return permList

# Call the function to compute the permutation list

# and store the result.

permList = createPermutationsList(nameList)

# Start the loop to display the values.

for perm in permList:

for val in perm:

print(val, end = " ")

print()

# Call the main() function.

if __name__ == "__main__":

# Prompt the user to enter the input.

nameList = input().split(' ')

permList = []

# Call the function to create and output

# the permutations of the list.

all_permutations(permList, nameList)

#endcode

What is the usage of "yield" in python?

Wewaii [24]

Answer:

Yield is a keyword in Python that is used to return from a function without destroying the states of its local variable and when the function is called, the execution starts from the last yield statement. Any function that contains a yield keyword is termed a generator. Hence, yield is what makes a generator.
