replace trademark symbol (™) when alone

I'm trying to remove trademark symbol (™) but only in the case it's not followed by any other symbol for instance I might have ’ which is a bad encoding of quotation mark (') so I don't want to remove trademark symbol (™) and hence broking the pattern that i'm using to replace xx™ with quotation mark.
dict = {};
chars = {
'\xe2\x84\xa2': '', # ™
'\xe2\x80\x99': "'", # ’
}
def stats_change(char, number):
if dict.has_key(char):
dict[char] = dict[char]+number
else:
dict[char] = number # Add new entry
def replace_chars(match):
char = match.group(0)
stats_change(char,1)
return chars[char]
i, nmatches = re.subn("(\\" + '|\\'.join(chars.keys()) + ")", replace_chars, i)
count_matches += nmatches
Input: foo™ oof
Output: foo oof
Input: o’f oof
Output: o'f oof
Any suggestions ?

This code returns the following error:
Error message
I have checked that file named x01.bat exists in:%USERPROFILE%\Desktop\JAVA\BATCH
I have tried to replace \ with / but windows doesn't recognize / as an way to access a directory.
I have tried to escape the backslash with another backslash. It only makes the same error with three backslashes instead of 2. (Yes I removed r before ' when I escaped a backslash with a backslash.)
I even tried to escape a backslash with a backslash before a backslash but error is the same with more backslashes.
Verdict: It seems that Python 3.6 on Windows 10 wants to add a backslash before a backslash no matter what I do. Because of that windows doesn't know where the .bat file is.
Any help is appreciated, please share your ideas!

For constructing paths in python, it is generally easier to use os.path.join
So something like
os.startfile(os.path.join(os.environ['USERPROFILE'], 'Desktop', 'JAVA', 'BATCH', 'x01.bat'))

It looks like you have an extra double quote at "bold")") ...
if not geschafft:
horst.write("Erwischt!",font=("Arial",14,"bold")")

horst.write("Erwischt!",font=("Arial",14,"bold")")
In this line, You have given an extra double quotes at the end.

How to decrypt in Python?

I am trying to decrypt a file in Python that I encrypted with another program. Some letters are correctly decrypted while others are not. I am not sure what is going on. All I essentially did was reverse the code for the decryption files. I think it has to do with the way it is iterating through the text, but I am not sure how to fix it.
Here is my decryption code:
decryption_library = {'%':'A','9':'a','#':'B','#':'b','1':'C','2':'c','3':'D','4':'d',
'5':'E','6':'e','7':'F','8':'f','0':'G','}':'g','{':'H',']':'h','[':'I',',':'i',
'.':'J','>':'j','<':'K','/':'k','0':'L','\-':'l','\"':'M',':':'m',';':'N',
'+':'n','$':'O','-':'o','$':'Q','%':'q','^':'R','&':'r','*':'S',
'(':'s',')':'T','~':'t','`':'U','5':'u','\\':'V','+':'v','=':'W','7':'w',
'~':'X',')':'x','2':'Y','*':'y',']':'Z','8':'z'}
orig_file = open('ENCRYPTED_Plain_Text_File.txt','r')
file_read = orig_file.read()
orig_file.close()
encrypt_file = open('DECRYPTED_Plain_Text_File.txt','w')
for ch in file_read:
if ch in decryption_library:
encrypt_file.write(decryption_library[ch])
else:
encrypt_file.write(ch)
encrypt_file.close()
encrypt_file = open('ENCRYPTED_Plain_Text_File.txt','r')
file_read = encrypt_file.read()
encrypt_file.close()
codes_items = decryption_library.items()
for ch in file_read:
if not ch in decryption_library.values() or ch == '.' or ch == ',' or ch == '!':
print(ch)
else:
for k,v in codes_items:
if ch == v and ch != '.':
print(k,end='')
Here is the encrypted text:
)]6 ^-94 ;-~ )9/6+
#2 ^$#5^) 7^$*)
)7- &-94( 4,+6&}64 ,+ 9 *6\-\--7 7--4,
%+4 (-&&* [ 2-5\-4 +-~ ~&9+6\- #-~]
%+4 #6 -+6 ~&9+6\-6&, \--+} [ (~--4
%+4 \---/64 4-7+ -+6 9( 89& 9( [ 2-5\-4
)- 7]6&6 ,~ #6+~ ,+ ~]6 5+46&}&-7~];
Here is what it should be:
The Road Not Taken
BY ROBERT FROST
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Here is what it decrypts to:

Your decryption_library is not correct. F.e for index ')' you have value 'T' and also 'x'

Python + getopt - Problems with parsing

I have some problems with writing some Gerrit http://code.google.com/p/gerrit/ hooks.
http://gerrit.googlecode.com/svn/documentation/2.2.0/config-hooks.html
If I parse the command line for
patchset-created --change --change-url --project --branch --uploader --commit --patchset
def main():
if (len(sys.argv) < 2):
showUsage()
exit()
if (sys.argv[1] == 'update-projects'):
updateProjects()
exit()
need = ['action=', 'change=', 'change-url=', 'commit=', 'project=', 'branch=', 'uploader=',
'patchset=', 'abandoner=', 'reason=', 'submitter=', 'comment=', 'CRVW=', 'VRIF=' , 'patchset=' , 'restorer=', 'author=']
print sys.argv[1:]
print '-----'
optlist, args = getopt.getopt(sys.argv[1:], '', need)
id = url = hash = who = comment = reason = codeReview = verified = restorer = ''
print optlist
for o, a in optlist:
if o == '--change': id = a
elif o == '--change-url': url = a
elif o == '--commit': hash = a
elif o == '--action': what = a

('--change-url', 'http://<hostname>:8080/308'),
('--project', 'private/bar'),
('--branch', 'master'),
('--uploader', 'xxxxxxx-xxxxx')]
I don't know why the script generates
'--uploader', 'xxxxxxx-xxxxx', 'xxxxxxx', '(xxxxxxxxxxxxx.xxxxxxx#xxx-xxxx.xx)'
and not
'--uploader', 'xxxxxxx-xxxxx xxxxxxx (xxxxxxxxxxxxx.xxxxxxx#xxx-xxxx.xx)'
because so the script dont't parse --commit --patchset ...
When I parse comment-added all things works:
Command line input:
-change I87f7802d438d5640779daa9ac8196aeb3eec8c2a
--change-url http://<hostname>.intra:8080/308

'http://<hostname>:8080/308',
'--project', 'private/bar',
'--branch', 'master',
'--author', 'xxxxxxx-xxxxx xxxxxxx (xxxxxxxxxxxxx.xxxxxxx#xxx-xxxx.xx)', <<< That's right!
'--commit', '49aae9befaf27a5fede51b498f0660199f47b899',
'--comment', 'asdf',
'--CRVW', '0',
'--VRIF', '0']

As the options names and values are space-separated, you have to put the values in quotes if they contain spaces themselves.
If you write --uploader xxxxxxx-xxxxx xxxxxxx (xxxxxxxxxxxxx.xxxxxxx#xxx-xxxx.xx), the last two strings will actually end up in args from the line
optlist, args = getopt.getopt(sys.argv[1:], '', need)
as they are not associated with --uploader

You should quote an argument, if it contains spaces, like for all commandline tools:
--uploader "xxxxxxx-xxxxx xxxxxxx (xxxxxxxxxxxxx.xxxxxxx#xxx-xxxx.xx)"

You may also consider using gnu_getopt() as it would allow you to mix option and non-option arguments.
From the Documentation
The getopt() function stops processing options as soon as a non-option argument is encountered
If you use gnu_getopt, the rest of the options namely commit and pathset will still be parsed correctly even though the uploader argument has missing quotes
