0 Basic python-3.7 There's a program Python read and write text

Today we introduce another program that reads and writes files

Let's stick to the simple program code first. And then through our many improvements. Hopefully, it will 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 ')
