Unable to print Dependent vowels - python-3.x

Question

I am reading the text file consisting of bengali words. But I am unable to print the dependent vowels like KA,KI etc...
Here is my sample code and output
import unicodedata
bengali_phoneme_maplist={u'অ':'A',u'আ':'AA',u'ই':'I',u'ঈ':'II',u'উ':'U',u'ঊ ':'UU',u'ঋ ':'R',u'ঌ ':'L',u'এ ':'E',u'ঐ ':'AI',u'ও ':'O',u'ঔ ':'AU',u'ক':'KA',u'খ ':'KHA',u'গ ':'GA',u'ঘ':'GHA',u'ঙ ':'NGA',u'চ ':'CA',u'ছ':'CHA',u'জ ':'JA',u'ঝ':'JHA',u'ঞ':'NYA',u'ট ':'TTA',u'ঠ':'TTHA',u'ড ':'DDA',u'ঢ':'DDHA',u'ণ ':'NNA',u'ত ':'TA',u'ত ':'THA',u'দ':'DA',u'ধ':'DHA',u'ন':'NA',u'প':'PA',u'ফ':'PHA',u'ব':'BA',u'ভ':'BHA',u'ম ':'MA',u'য ':'YA',u'র':'RA',u'ল ':'LA',u'শ ':'SHA',u'ষ':'SSA',u'স ':'SA',u'হ':'ha',u' া ':'AAV',u' ি':'IV',u'ী':'IIV',u'ু':'UV',u'ূ':'UUV',u'ৃ':'RRV',u'ৄ ':'RR',u'ৄ':'EV',u' ৈ':'EV',u'়':'NUKTHA',u'ঽ':'AVAGRAHA'}
bengali_phoneme_maplist_normalise={unicodedata.normalize('NFKD',k):v
for k,v in bengali_phoneme_maplist.items()}
with open('bengali.txt','r')as infile:
lines=infile.readlines()
for index,line in enumerate(lines):
print('Phonemes in line{0}.total{1} symbols'.format(index,len(line)))
unknown=[]
words=line.split()
for word in words:
print(word,':',sep=' ', end='')
for character in word:
c=unicodedata.normalize('NFKD',character).casefold()
try:
print(bengali_phoneme_maplist_normalise[c],sep='',end='')
except KeyError:
print('_',sep='',end='')
if c not in unknown:
unknown.append(c)
print()
if unknown:
print('Unrecognised symbols:{0},total {1} symbols'.format(','.join(unknown),len(unknown)))
Sample input:
শিল্পাঞ্চলে ঢোকার মুখে, স্ন্যাক্সবারে খাবার কিনছিলেন, বহুজাতিক তথ্যপ্রযুক্তি সংস্থার কর্মী, শুভময় বন্দ্যোপাধ্যায়

Answer 1

(Note that I know nohting about Bengali. :)
There are a few problems in your code:
There are many extra SPACE chars in the bengali_phoneme_maplist definition. For example, u'ঊ ' should be u'ঊ'. And it seems like it's not easy to input chars like u'া' in an text editor so I suggest you directly use unicode in the code, like '\u09be':'AAV'. (Actually I'd suggest you use '\uxxxx' for all chars and write the real chars in comments.)
u'ত':'TA',u'ত':'THA' should change to u'ত':'TA',u'থ':'THA'.
The chars in bengali_phoneme_maplist are not complete. For example there's no ো , ৌ , ্ and ং
After fixing these errors you will get the correct result.
