Replace four letter word in python

Question

I am trying to write a program that opens a text document and replaces all four letter words with **. I have been messing around with this program for multiple hour

Answer 1

You need replace the letter w in w+ on line 4: file1 = open(filename, 'w') haves to be file1 = open(filename, 'w+') (I was working on this project too so this was my code)

import os
import time
localtime = time.asctime( time.localtime(time.time()) )
a = input("What is your first name?   ").title()
b = input("And your last name?   ").title()
c = input("What is your e-mail adderess?   ")
d = input("And your phone number?   ")
f = input("When were you born? (02-01-1900 is 1 February 1900)")
print(a)
print(b)
print(c)
print(d)
print(f)
e = input("Is this correct? (Y\N)  ")
g = (a+"-"+b)




if e == "Y" or "y":
    new_path = '/users/Pivo/registreren/%s.txt' % g
    new_days = open(new_path,'w+')
    new_days.write(localtime)
    new_days.write('\n')
    new_days.write(a)
    new_days.write(" ")
    new_days.write(b)
    new_days.write('\n')
    new_days.write(c)
    new_days.write('\n')
    new_days.write(d)
    new_days.write('\n')
    new_days.write(f)
    new_days.write('\n')
    new_days.write('\n')
    new_days.write('\n')
    new_days.write('\n')
    new_days.close()
    print("Okay, done!")
if e == "N" or "n":
    os.startfile("C:/Users/Pivo/registreren/registreren.py")
