From JoyceUlysses.txt -- words occurring exactly once
by HenHanna June 1, 2024

June 1, 2024

Given a text file of a novel (JoyceUlysses.txt) ... could someone give me a pretty fast (and simple) Python program that'd give me a list of all words occurring exactly once? -- Also, a list of words occurring once, twice or 3 times re: hyphenated words (you can treat it anyway you like) but ideally, i'd treat [editor-in-chief] [go-ahead] [pen-knife] [know-how] [far-fetched] ... as one unit.

Serializing pydantic enums
by Larry Martell May 29, 2024

May 29, 2024

Just getting started with pydantic. I have this example code: class FinishReason(Enum): stop = 'stop' class Choice(BaseModel): finish_reason: FinishReason = Field(...) But I cannot serialize this: json.dumps(Choice(finish_reason=FinishReason.stop).dict()) *** TypeError: Object of type FinishReason is not JSON serializable I get the object not the value: (Pdb) Choice(finish_reason=FinishReason.stop) Choice(finish_reason=<FinishReason.stop: 'stop'>) Also tried it with .value, same result. What am I missing here?

For a simple conversion that has a little touch of generality: s1 = 'this is a test' def convert(i, ch): return ch.upper() if i % 2 else ch result = ''.join([convert(i, ch) for i, ch in enumerate(s1)]) print(result) # tHiS Is a tEsT However, this has a weakness: what to do about spaces. Should they be counted among the characters to be uppercased? or should they not be included in the count of the alternation? If you want to uppercase every other letter that is not a space, things become a little more complicated. And then do you want this to apply to all whitespace or only spaces? If you want to skip changing spaces, then you need to track the state of converted characters in some way. It would probably be easier (and more readable) to use a "for x in t:" construction: def convert(convert_this, ch): """Convert character ch if convert_this is True. Don't convert spaces. """ if convert_this: if ch == ' ': return (convert_this, ch) elif convert_this: return (False, ch.upper()) return (True, ch) convert_next = False result = '' for ch in s1: convert_next, ch = convert(convert_next, ch) result += ch print(result) # tHiS Is A TeSt There could be even more complications if you allow non-ascii characters but you were asking about processing character by character so I won't get into that.

Flubbed it in the second interation through the string: range error... HOW?

The following is my effort to understand how to process a string, letter, by letter: def myfunc(name): index = 0 howmax = len(name) # while (index <= howmax): while (index < howmax): if (index % 2 == 0): print('letter to upper = {}, index {}!'.format(name[index], index)) name = name[index].upper() print('if block {} and index {}'.format(name[index], index)) elif (index % 2 > 0): print(index) print('Start: elseif block, index is {}, letter is {}'.format(index, name)) # print('letter to lower = {}'.format(name[index])) # print('Already lowercase do noting: name = {}'.format(name[index])) index += 1 # index = name.upper() return name myfunc('capitalism') Error message: Not making sense, index is 1, letter s/b 'a'letter to upper = c, index 0! if block C and index 0 1 Start: elseif block, index is 1, letter is C --------------------------------------------------------------------------- IndexError Traceback (most recent call last) Cell In[27], line 21 17 # index = name.upper() 19 return name ---> 21 myfunc('capitalism') Cell In[27], line 8, in myfunc(name) 6 while (index < howmax): 7 if (index % 2 == 0): ----> 8 print('letter to upper = {}, index {}!'.format(name[index], index)) 9 name = name[index].upper() 10 print('if block {} and index {}'.format(name[index], index)) IndexError: string index out of range*************************************************** So, I'm doing something...
