Need help on this piece of a program: So i needed to encrypt a text file by putt

Question

Need help on this piece of a program:

So i needed to encrypt a text file by putting a 5 after every character. Now I am asked to take a file encrypted this way, and decrypt out the 5's. Is there a way to dejoin, or is it not going to be as straight forward? Keep in mind this is for an intro level Python3 class.

def Encrypt():
   newName = input("Enter a name for the new encyrpted file: ")
   infile = open("copy.txt", "r")
   outfile = open(newName, "w")
   data = infile.read()
   data = "5".join(data)
   outfile.write(data)
   infile.close()
   outfile.close()

Explanation / Answer

newName = input("Enter a name for the new encyrpted file: ")
infile = open("copy.txt", "r")
outfile = open(newName, "w")
data = infile.read()
data = "5".join(data)
outfile.write(data)
infile.close()
outfile.close()

def encryption():

newname=input(“Enter a name for the new encrypted file:”)

newname=int(newname)

dummy=5

inputfilename=(“copy.text”,”w”)

outputfilename=open(newName,”w”)

mykey=5

mymode=‘encrypt’

if not os.path.exists(input filename)

print(the file doesnot exist.quit(input filename)

sys.exit()

data=inputfilename.read()

data=“5”.join(data)

fileobj=open(inputfile)

pp=fileobj.read(data)

inputfile.close()

print(Mymode.name())

starttime=time.time()

if mymode==‘encrypt’

translated=transpositionencrypt.encrypt(mykey,5)

print(’total time,newsman,5’)

outputfileobj=open(output filename,’w’)

outputfileobj.write(translated)

outputfile.close()

print(output filename)
