Question

我有一个程序，该程序将文本中用星号分隔的法语单词连接起来。因为我希望该程序可供不同的用户使用，所以我想在程序中插入一行，要求用户输入文本文件的路径或仅输入文本名称……该怎么做？仅使用功能“输入”？我不知道……有没有一种优雅的方法可以要求用户运行该程序？该程序如下：

import nltk
from nltk.tokenize import word_tokenize
import re



with 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:
           continue

for i, w in enumerate(l):
    if w == "*":
        l.remove(l[i-1])
    else:
        continue

for i, w in enumerate(l):
    if w == "$":
        l.remove(l[i+1])
    else:
        continue


text=' '.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:
        continue


final_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')

Answer 1

您可以按照自己喜欢的任何方式进行操作，但是让用户写出文件的完整路径既繁琐又容易出错。您可以做的是拥有一个“监视文件夹”。这是您的脚本已经知道的文件夹，甚至可能与脚本位于同一文件夹中。

一个小例子：

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)

输出：

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

Answer 2

from pathlib import Path
data_folder = Path(input("type the path you would like to use"))
file_to_open = data_folder / 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径，而只是使用位于脚本位置的本地文件，则只需询问用户名称，然后直接用f = open(filename)打开即可。

注意：如果您想知道为什么/中有file_to_open而不是字符串串联+ this解释了原因。

要求用户输入文件以使用python运行程序
