User prompt as file to read


K

I'm trying to create a program that will prompt the user for a list of textfiles to read from, then read those text files and build a dictionary of all the unique words found. Then finally put those unique words into anotherfile and make it alphabetical order.

What I've got:

import string

s = input("Enter a file name: ") + ".txt"
filepath = "I:\\" + s

# remove all punctuation marks and make lower case
s_nopunct = "".join(c for c in s if c not in string.punctuation).lower()

# convert to a sorted list of unique words via set comprehension
list_unique = sorted(list({word for word in s_nopunct.split()}))

print("\nSorted list of unique words in sentence:")
print(list_unique)

with open("C:\\Users\\Desktop\\words.dat", "w") as f:
for x in list_unique:
f.write(x + "\n")

I need help making it so that the user is prompted to enter at least 3 files.
And also, I tried making those unique words to write to another file (I gotit that far), but how do I make it more of an arbitrary path (rather than the C:\Users etc) since I need it so that anyone can run that program and write/find to that file.

Specify python version and os. I assume python 3 and Windows.
What I've got:

import string

s = input("Enter a file name: ") + ".txt"
filepath = "I:\\" + s

So you've got a filename. You're not using it for anything.
Where's your open? Where's your read or readline?

# remove all punctuation marks and make lower case
s_nopunct = "".join(c for c in s if c not in string.punctuation).lower()

Are you sure you want a single string nearly the total size of
your 3 files? Could be huge. Might be better to do it
incrementally.

It's a lot safer to include the characters you want, instead of
excluding some of the ones you don't. And many valid words
contain punctuation such as apostrophe.
# convert to a sorted list of unique words via set comprehension
list_unique = sorted(list({word for word in s_nopunct.split()}))


print("\nSorted list of unique words in sentence:")
print(list_unique)

with open("C:\\Users\\Desktop\\words.dat", "w") as f:
for x in list_unique:
f.write(x + "\n")

I need help making it so that the user is prompted to enter at least 3 files.

Need a while loop for that.
And also, I tried making those unique words to write to another file (I got it that far), but how do I make it more of an arbitrary path (rather than the C:\Users etc) since I need it so that anyone can run that program and write/find to that file.

That could be another input, or it could be a command line
parameter. Your choice.
