title: Can't get new line to work in python?
body: <p>This is the code that i'm currently using to try to get a new line. Sadly it just rewrites the first line in the program. What is going on? If you can help I will be very thankful.</p>
  
  <pre><code>import itertools
  import string
  import sys, os, cmd
  
  from datetime import datetime
  FMT = '%Y-%m-%d %H:%M:%S'
  passwordstried = 0
  
  
  numbers = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '0',]
  symbols = ["!","@","#","$","%","^","&amp;","*","(",")","_","-","'",'"',":",";","+","=","[","{","]","}","&lt;",",","&gt;",".","?","/","|","\"","~","`"]
  lowercaseletters = ["q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","g","h","j","k","l","z","x","c","v","b","n","m"]
  uppercaseletters = ["Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","G","H","J","K","L","Z","X","C","V","B","N","M"]
  
  
  stuff = lowercaseletters + uppercaseletters + numbers + symbols
  
  
  if (input("Do you have the length of the password?") == 'y'):
      lengthstartingvalue = int(input("Password length: "))
  else:
      lengthstartingvalue = 1
  
  
  starttime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
  print(starttime)
  
  
  starttime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
  for L in range(lengthstartingvalue, len(stuff)+1):
      for subset in itertools.combinations_with_replacement(stuff, L):
          #print(subset)
  
  
          password = ''.join(subset)
          print(password)
  
          file = open("generatedpasswords.txt","w")
          file.write(str(password) + '\n')
  
          passwordstried = passwordstried + 1
      if (L&gt;lengthstartingvalue+1):
          break
  
  endtime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
  elapsed = datetime.strptime(endtime, FMT) - datetime.strptime(starttime, FMT)
  print ('Time elapsed:',elapsed)
  print ('Passwords tried:',passwordstried)
  file.close()
