Python的 - 組順序的數組成員

Question

我想修改我的文字是這樣的：

arr = [] 
# arr is full of tokenized words from my text 

例如：

"Abraham Lincoln Hotel is very beautiful place and i want to go there with 
Barbara Palvin. Also there are stores like Adidas ,Nike , Reebok." 

編輯：基本上，我想用istitle檢測正確的名稱，並將組（）和isAlpha（）for for語句如：

for i in arr: 
    if arr[i].istitle() and arr[i].isAlpha 

在示例arr中，直到下一個單詞不是他的第一個單詞字母大寫。

arr[0] + arr[1] + arr[2] = arr[0] 
#Abraham Lincoln Hotel 

這就是我要與我的新編曲：

['Abraham Lincoln Hotel'] is very beautiful place and i want to go there with['Barbara Palvin']. ['Also'] there are stores like ['Adidas'], ['Nike'],['Reebok'].

「也」不是我的問題，將是有益的，當我嘗試，以配合我的數據集。

Answer 1

你可以做這樣的事情：

sentence = "Abraham Lincoln Hotel is very beautiful place and i want to go there with Barbara Palvin. Also there are stores like Adidas, Nike, Reebok." 
all_words = sentence.split() 
last_word_index = -100 
proper_nouns = [] 
for idx, word in enumerate(all_words): 
    if(word.istitle() and word.isalpha()): 
     if(last_word_index == idx-1): 
      proper_nouns[-1] = proper_nouns[-1] + " " + word 
     else: 
      proper_nouns.append(word) 
     last_word_index = idx 
print(proper_nouns) 

這段代碼：

• 拆分所有的單詞放入一個列表
• 遍歷所有的單詞和
  • 如果最後一個大寫的字是以前的話，它會追加它到列表中的最後一個條目
  • 否則它會將該詞作爲新條目存儲在列表中
  • 記錄最後一個索引alized字被發現

Answer 2

這是你在問什麼？

sentence = "Abraham Lincoln Hotel is very beautiful place and i want to go there with Barbara Palvin. Also there are stores like Adidas ,Nike , Reebok." 

chars = ".!?,"         # Characters you want to remove from the words in the array 

table = chars.maketrans(chars, " " * len(chars)) # Create a table for replacing characters 
sentence = sentence.translate(table)    # Replace characters with spaces 

arr = sentence.split()       # Split the string into an array whereever a space occurs 

print(arr) 

的輸出是：

['Abraham', 
'Lincoln', 
'Hotel', 
'is', 
'very', 
'beautiful', 
'place', 
'and', 
'i', 
'want', 
'to', 
'go', 
'there', 
'with', 
'Barbara', 
'Palvin', 
'Also', 
'there', 
'are', 
'stores', 
'like', 
'Adidas', 
'Nike', 
'Reebok'] 

注意這個代碼：即在chars變量的任何字符將來自陣列中的字符串被刪除。代碼中包含Explenation。

要卸下非名稱只是這樣做：

import string 
new_arr = [] 

for i in arr: 
    if i[0] in string.ascii_uppercase: 
     new_arr.append(i) 

此代碼將包括以大寫字母開頭的所有單詞。

爲了解決這個問題，你需要改變chars到：

chars = "," 

並更改上面的代碼：

import string 
new_arr = [] 
end = ".!?"  

b = 1 
for i in arr: 
    if i[0] in string.ascii_uppercase and arr[b-1][-1] not in end: 
     new_arr.append(i) 
    b += 1 

，這將輸出：

['Abraham', 
'Lincoln', 
'Hotel', 
'Barbara', 
'Palvin.', 
'Adidas', 
'Nike', 
'Reebok.']
