#Write a function called "replace_all" that accepts three #arguments: # # - target_string, a string in which to search. # - find_string, a string to search for. # - replace_string, a string to use to replace every instance # of the value of find. # #The arguments will be provided in this order. Your function #should mimic the behavior of "replace", but you cannot use #that function in your implementation. Instead, you should #find the result using a combination of split() and join(), #or some other method. # #Hint: This exercise can be complicated, but it can also #be done in a single short line of code! Think carefully about #the methods we've covered. #Write your function here!

Here is the function replace_all:

def replace_all(target_string,find_string,replace_string):

   result_string = replace_string.join(target_string.split(find_string))  

   return result_string

#if you want to see the working of this function then you can call this function using the following statements:

target_string = "In case I don't see ya, good afternoon, good evening, and good night!"

find_string = "good"

replace_string = "bad"

print(replace_all(target_string, find_string, replace_string)

Explanation:

The above program has a function called replace_all that accepts three arguments i.e target_string, a string in which to search ,find_string, a string to search for and replace_string, a string to use to replace every instance of the value of find_string. The function has the following statement:

replace_string.join(target_string.split(find_string))  

split() method in the above statement is splits or breaks the target_string in to a list of strings based on find_string. Here find_string is passed to split() method as a parameter which works as a separator. For example above:

target_string = In case I don't see ya, good afternoon, good evening, and good night!

find_string = good

After using target_string.split(find_string) we get:

["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night']

Next join() method is used to return a string concatenated with the elements of target_string.split(find_string). Here join takes the list ["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night'] as parameter and joins elements of this list by 'bad'.

replace_string = bad

After using replace_string.join(target_string.split(find_string))  we get:

In case I don't see ya, bad afternoon, bad evening, and bad night!  

The program and output is attached as a screenshot.

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.

hope this ! : 3
