Today we introduce another program that reads and writes files

We first paste the simple program code, and then through our many improvements, we hope to eventually become a simple text editor

Here's our simplest code:

' crudfile--read-write file ' def readwholefile (filename):    ' Read the entire file ' files    = open (FileName, mode= ' R ')    text = [] for    Eachline in file:        print (eachline)        text.append (eachline)    return textdef WriteFile (fileName):    ' Write file '    handler = open (FileName, mode= ' W ') while    True:        inputtext = input (' > ')        if inputtext = = ' exit ': C13/>break        Else:            handler.write (Inputtext) Try:    filename = "test.txt"    writefile (filename);    Textinfile = Readwholefile (fileName); except IOError as E:    print (e)    print (' file does not exist ')
