我有兩個檔案。一個包含 id，另一個包含每個 id 的句子，但像這個例子一樣幾乎沒有變化
檔案1：
111_3232
111_ewe2
111_3434
222_3843h
222_39092
檔案2：
111 some_text_1 some_text_1
222 some_text_2 some_text_2
我需要用 id 和它的句子制作一個檔案
111_3232 some_text_1 some_text_1
111_ewe2 some_text_1 some_text_1
111_3434 some_text_1 some_text_1
222_3843h some_text_2 some_text_2
222_39092 some_text_2 some_text_2
我試過這段代碼
import os
f = open("id","r")
ff = open("result","w")
fff = open("sentences.txt","r")
List = fff.readlines()
i =0
for line_id in f.readlines():
for line_sentence in range(len(List)):
if line_id in List[i]:
ff.write(line_sentence)
else :
i =1
但得到了
if line_id in List[i]:
IndexError: list index out of range
因為我從file2得到了整行，而不僅僅是id......有沒有比我做得更好的方法
編輯
我嘗試使用 panads 但我對這段代碼不太熟悉
df = pd.read_csv('sentence.csv')
for line_id in f.readline():
for line_2 in df.iloc[:, 0] :
for (idx, row) in df.iterrows():
if line_id in line_2:
ff.write(str(row) '\n')
else :
ff.write("empty" '\n')
但得到了錯誤的資料，因為我無法很好地捕捉到正確的行

基本方法
with open('file1.txt', 'r') as fd1, open('file2.txt', 'r') as fd2:
lines1 = fd1.read().split() # remove \n
lines2 = fd2.readlines()
new_text = ''
for l1 in lines1:
for id_, t1, t2 in (l.split() for l in lines2):
if l1.startswith(id_):
new_text = f'{l1} {t1} {t2}\n'
with open('file3.txt', 'w') as fd:
fd.write(new_text.strip())
uj5u.com熱心網友回復：
實作結果的一種方法是將sentences和file_id對存盤在字典中并遍歷 id 檔案內容以獲得結果
sentences_dict = {}
# read all sentences into a dictionary as key value pair
with open("sentences.txt", "r") as sentences_file:
for line in sentences_file.read().splitlines():
split_lines = line.split(" ")
sentences_dict.update({split_lines[0].strip(): " ".join(split_lines[1:])})
result_file = open("result.txt", "w")
# iterate over id file and match the starting text
with open("id.txt", "r") as id_file:
for file_id in id_file.read().splitlines():
txt = sentences_dict.get(file_id.split("_")[0], "")
result_file.write(f"{file_id}{txt}\n")
result_file.close()
with除非您與關鍵字一起打開，否則請確保始終明確關閉檔案。
