假设TXT文件中的所有部分都以“-”开头,您可以创建两个字符串标志,并将它们用作嵌套for循环中的检查,如下所示:

import os
import sys

def get_ingredients_from_file():
  recipe_file = open("/Filepath/", "r")
  final_ingredients_list = list()
  string_flag1 = "-Ingredients"
  string_flag2 = "-"

  for line in recipe_file:                                                                                   
    if line.startswith(string_flag1):           #Line is ingredients
      for line in recipe_file:                  
        if not line.startswith(string_flag2):   #Loop until second string flag is encountered
          final_ingredients_list.append(line)   #append lines to the list
        else:
          break

希望这有帮助。
