Write an application that determines whether the first two files are located in the same folder as the third one. The program sh

marissa [1.9K]

Answer:

The program in Python is as follows:

fname1 = input("Filepath 1: ").lower()

fname2 = input("Filepath 2: ").lower()

fname3 = input("Filepath 3: ").lower()

f1dir = ""; f2dir = ""; f3dir = ""

fnamesplit = fname1.split("/")

for i in range(len(fnamesplit)-1):

f1dir+=fnamesplit[i]+"/"

fnamesplit = fname2.split("/")

for i in range(len(fnamesplit)-1):

f2dir+=fnamesplit[i]+"/"

fnamesplit = fname3.split("/")

for i in range(len(fnamesplit)-1):

f3dir+=fnamesplit[i]+"/"

if f1dir == f2dir == f3dir:

print("Files are in the same folder")

else:

print("Files are in the different folder")

Explanation:

The next three lines get the file path of the three files

fname1 = input("Filepath 1: ").lower()

fname2 = input("Filepath 2: ").lower()

fname3 = input("Filepath 3: ").lower()

This initializes the directory of the three files to an empty string

f1dir = ""; f2dir = ""; f3dir = ""

This splits file name 1 by "/"

fnamesplit = fname1.split("/")

This iteration gets the directory of file 1 (leaving out the file name)

for i in range(len(fnamesplit)-1):

f1dir+=fnamesplit[i]+"/"

This splits file name 2 by "/"

fnamesplit = fname2.split("/")

This iteration gets the directory of file 2 (leaving out the file name)

for i in range(len(fnamesplit)-1):

f2dir+=fnamesplit[i]+"/"

This splits file name 3 by "/"

fnamesplit = fname3.split("/")

This iteration gets the directory of file 3 (leaving out the file name)

for i in range(len(fnamesplit)-1):

f3dir+=fnamesplit[i]+"/"

This checks if the file directories hold the same value

This is executed, if yes

if f1dir == f2dir == f3dir:

print("Files are in the same folder")

This is executed, if otherwise

else:

print("Files are in the different folder")
