#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!

Answer:

Here is the function called replace_all:

def replace_all(target_string,find_string,replace_string):

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

return result_string

#To see how this function operates, you can invoke it using the following code:

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 aforementioned program contains a function named replace_all that accepts three parameters: target_string, which is the string to search within; find_string, which is the string you are searching for; and replace_string, which is the string utilized to replace all occurrences of find_string. The function executes the following statement:

replace_string.join(target_string.split(find_string))

The split() method in this context divides target_string into a list according to find_string. Here, find_string is provided to the split() method as a parameter, acting as a separator. For example:

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

find_string = good

After executing target_string.split(find_string), we obtain:

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

The join() method then concatenates the elements of the list generated by target_string.split(find_string). Here, join takes that list as a parameter and connects its elements using 'bad'.

The resulting replace_string = badSubsequently, after using replace_string.join(target_string.split(find_string)), we generate:

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