Question

How would I open a file and encrypt that file from a dictionary in Python? Attached is a picture of my current code. I am currently stuck at the getFiles() and convert(inputFile, outputFile) functions.

def main ):
userInput - displayMenuAndGetOption )
if userInput-"E" or userInput "D":
getFiles ()
elif userInput-"Q
print ("nErrorInvalid option.")
input ("nRun complete. Press the Enter key to exit.")
def displayMenuAndGetoption ):
print ("File Encryption Program\n")
print ("E Encrypt a file\nD = Decrypt a file\nQ Quit the Program")
userInput= input ("\nEnter menu selection (E, D, or Q) : ").upper()
return userInput
def getFiles 0:
outFileopen ("encryptedFile.txt", "w")
try:
encrypt File
open (input ("Enter the file to ENCRYPT. Press Enter alone to abort.
"),
'r')
except FileNotFoundError:
print ("Error - that file does not exist. Try again.")
convert (encryptFile, outFile)
def convert (inputFile, outputFile):
# Encryption and decryption are inverse of one another
CODE = {'A' : ' ) ' , ' a' : ' 0' , 'B':'(','b':'9','C':'*','c':18',\

Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;
