[英]is it possible to write a program in python that will ask the user to enter the output of an array?
[英]ask user enter a file to run the program with python
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 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')
您可以按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。 您可以做的是擁有一個“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於同一文件夾中。
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於腳本位置的本地文件,您只需要詢問用戶其名稱並直接使用f = open(filename)
打開它。
注意:如果您想知道為什么file_to_open
有一個/
而不是字符串連接+
這解釋了原因。
