In Python 3, map returns an iterable object of type map, and not a subscriptible list, which would allow you to write map[i]. To force a list result, write

payIntList = list(map(int,payList))

However, in many cases, you can write out your code way nicer by not using indices. For example, with list comprehensions:

payIntList = [pi + 1000 for pi in payList]
for pi in payIntList:
    print(pi)

In Python 3 map returns a generator. Try creating a list from it first.

with open("/bin/ls", "rb") as fin: #rb as text file and location 
  buf = fin.read()
bytes = list(map(ord, buf))
print (bytes[:10])
saveFile = open('exampleFile.txt', 'w')
saveFile.write(bytes)
saveFile.close()

If you think that is ugly, you can replace it with a list generator:

bytes = [ord(b) for f in buf]

In Python 3 .keys() returns an iterator, which you can't slice. Convert it to a list before slicing.

fdist1 = FreqDist(text1)
vocabulary1 = fdist1.keys()
x = list(vocabulary1)[:50]
# or...
vocabulary1 = list(fdist1.keys())
x = vocabulary1[:50]

Hi @tye-shutty, and thanks for posting. Looking at the traceback, and investigating further, this seems to have something to do with newer versions of PIL/pillow. As defined in its requirements.txt, pdfplumber requires Pillow>=8.4. The code works fine for me with 8.4 (and 9.0) but falis (with the same error) when I upgrade to the latest version, 9.1, released just 10 days ago. (Specifically, it appears to stem from the addition of these lines checking for negative crops.)

If you'd like to check for your particular case, can you add this line to your script and rerun on your two machines:

import PIL
print(PIL.__version__)

If that's indeed the case for you, the immediate fix would be to run pip install pillow==9.0 in your relevant environment. In the long run, I'll aim to release a fix to the relevant code in pdfplumber.
