我有一個程序可以連接文本中用星號分隔的法語單詞。因為我想讓這個程序被不同的用戶使用，所以我想在程序中插入一行，要求用戶輸入文本文件的路徑或者簡單地輸入文本的名稱……怎么做？只使用函數“輸入”？我不知道......有沒有一種優雅的方式讓用戶運行程序？該程序如下：import nltkfrom nltk.tokenize import word_tokenizeimport rewith open ('text-test.txt') as tx: words = word_tokenize(tx.read().lower())with open ('Fr-dictionary.txt') as fr: dic = word_tokenize(fr.read().lower())l=[ ]errors=[ ]out_file=open("newtext.txt","w")for n,word in enumerate (words): l.append(word) if word == "*": exp = words[n-1] + words[n+1] print("\nconcatenation error:", exp) if exp in dic: l.append(exp) l.append("$") errors.append(words[n-1]) errors.append(words[n+1]) else: continuefor i, w in enumerate(l): if w == "*": l.remove(l[i-1]) else: continuefor i, w in enumerate(l): if w == "$": l.remove(l[i+1]) else: continuetext=' '.join(l)print('\n\n',text)e=len(errors)print('\n',e/2,'WORDS CONCATENATED IN TEXT',errors)user=input('\nREMOVE * AND $ FROM TEXT? Type "Y" for yes or "N" for no:')for x in l: if user=='Y' and x=='*': l.remove(x) elif user=='Y' and x=='$': l.remove(x) else: continuefinal_text=' '.join(l)print('\n\n', final_text)user2=input('\nWrite text to a file? Type "Y" for yes or "N" for no:')if user2 =='Y': out_file.write(final_text) out_file.close() print('\nText named "newtext.txt" written to a file')

您可以按照自己喜歡的方式進行操作，但讓用戶寫出文件的完整路徑既乏味又容易出錯。你可以做的是有一個“監視文件夾”。這是您的腳本已經知道的文件夾，甚至可能與您的腳本位于同一文件夾中。
一個小例子：
import os
import sys
# This prints the folder where the script is run.
script_directory = os.path.dirname(sys.argv[0])
print(script_directory)
# This is the folder we want to keep track off
our_watched_folder = f'{script_directory}/watch_folder'
print(our_watched_folder)
# Let's see if a user dropped a new file in our folder
print("Files in watch folder")
for file in os.listdir(our_watched_folder):
print(file)
輸出：
C:/your_script_folder/
C:/your_script_folder/watch_folder
Files in watch folder
a_new_text_file.txt
some_old_textfile1.txt
some_old_textfile2.txt

from pathlib import Path
data_folder = Path(str(input("type the path you would like to use")))
file_to_open = data_folder / str(input("insert the file you would like to use with its extension"))
f = open(file_to_open)
如果您不想使用完整路徑而只想使用位于腳本位置的本地文件，您只需要詢問用戶其名稱并f = open(filename)直接打開它。
注意：如果您想知道為什么有/infile_to_open而不是字符串連接，+ 這解釋了原因。
