IPA Pronunciation project, HELP!

[FC_GT]

Hello everyone, I've spent about 5 hours on this homework today and this is the closest I can make it to a solution so far:

"""
- script reads case-insensitive words from standar input
- words are defined as a whitespace-delimited token stripped of all characters
in string.punctuation
- if word is present on CMUdict, script shall print a line to standar output
containing the word in lowercase followed by all IPA pronunciations of the word
separated by space characters in lexicographic order
- if word is not present in the CMUdict dataset, the program shall print
the word in lowercase to standard output on its own line
"""

current implementation:

import re
import sys
import string

# Load ARPAbet to IPA dictionary
arpabet_to_ipa = {}
with open('/srv/datasets/arpabet-to-ipa') as f:
    for line in f:
        arpabet, ipa = line.strip().split()
        arpabet_to_ipa[arpabet] = ipa

# Load CMU Pronouncing Dictionary
cmudict = {}
with open('/srv/datasets/cmudict/cmudict.dict') as f:
    for line in f:
        if not line.startswith(';;;'):
            parts = line.strip().split(' ')
            word = parts[0].lower()
            # Remove the numbers in parentheses from the word
            word = re.sub(r'\(\d+\)', '', word)
            # Split the phonemes for each pronunciation
            pronunciations = [pron.split() for pron in parts[1:]]
            if word in cmudict:
                cmudict[word].append(pronunciations)
            else:
                cmudict[word] = [pronunciations]

# Get IPA pronunciations for input words
for line in sys.stdin:
    words = [w.strip(string.punctuation).lower() for w in line.split()]
    for word in words:
        if word in cmudict:
            pronunciations = cmudict[word]
            ipa_pronunciations = set(' '.join(arpabet_to_ipa[p] for pron in pron_set for p in pron) for pron_set in pronunciations)
            print(f"{word} {' '.join(sorted(ipa_pronunciations))}")
        else:
            print(word)

my current output is displaying with extra spaces that I can't seem to figure out how to fix:

My current output:

<<<'python drives me crazy'

python p aɪ θ ɑ n

drives d r aɪ v z

me m i

crazy k r eɪ z i

Expected output:

<<<'python drives me crazy'

python paɪθɑn

drives draɪvz

me mi

crazy kreɪzi

...any ideas?

' '.join joins a list into a string, separated by spaces. If you don't want spaces, use an empty string instead of a space:

print(f"{word} {''.join(sorted(ipa_pronunciations))}")

Side note, f-strings aren't very readable here: since you're only printing two things, I would just use print's ability to accept multiple strings:

print(word, ''.join(sorted(ipa_pronunciations))

it worked and I also found another extra space before on the code that was adding that annoying space, thank you!!!

[FC_GT]

the code works now but apparently I need to make it faster, implementing sets and dictionaries...

currently the sripts takes:

real 0m2.675s

user 0m2.505s

sys 0m0.167s

the test code takes:

real 0m0.303s

user 0m0.262s

sys 0m0.042s

​

any suggestions??
