Removing newline character - encryption

Question

So currently I've had a problem for the past few hours. I've looked through many stack overflow posts and have tried every suggestion. What my problem is, is I have a program that grabs words from a text file and gives them an MD5 encryption.
fileName = raw_input("> ")
if fileName.endswith(".txt") or fileName.endswith(".lst"):
fopen = open(fileName, 'r')
else:
fileName = fileName + ".txt"
fopen = open(fileName, 'r')
m = hashlib.md5()
for line in fopen:
sleep(1)
m.update(line)
encHash = m.hexdigest()
hashed = [line, encHash]
new_line = []
for elem in hashed:
new_line.extend(elem.strip('\n').split(' '))
searchfile = open("Passwords.txt").read()
if line in searchfile:
print ""
else:
fopen = open("Passwords.txt", 'a')
fopen.write(str(hashed))
fopen.write("\n")
fopen.close
print str(new_line)
Now as you can see, I've already dealt with the new line characters being outputted. But the encrypted version still has the \n at the end. So instead of "12345" being encrypted "12345\n" is.
I've tried rstrip(), and strip(). But it doesn't seem to work! Any help would be greatly appreciated.
Thanks
Paul
EDIT
I don't know what I did, I just re-wrote the code and its working fine! Thanks for all the suggestions.
elif choice == "2":
os.system('clear')
fileName = raw_input('Filename: ')
fopen = open(fileName, 'rb')
for line in fopen:
line = line.rstrip('\n')
enc = hashlib.md5()
enc.update(line)
encHash = enc.hexdigest()
hashed = {line:encHash}
fwrite = open('Password.txt', 'a')
hashed = str(hashed)
data = open("Password.txt").read()
if hashed in data:
print hashed
else:
fwrite.write(hashed)
fwrite.write("\n")
fwrite.close
print hashed

I don't know Python but it sounds like it could be related to the way you're opening the file.
Try using open(fileName, 'rb') instead of open(fileName, 'r').
This link describes the \r\n \n diffs. Opening a file up as binary will convert the newline character to newline sequence respective of the system you are running the code on.
