Python 如何提取和打印，保持原始输入字符串中出现的顺序，匹配这些 RegEx 模式之一的子字符串

我在打印字符串中所需的元素时遇到了一些问题，因为这些所需的元素响应不同的模式(在本例中，我将其简化为3 regex patterns).如下面的示例所示，目标是打印存储在substring_to_extract_1或/和substring_to_extract_2变量中的内容，并且这些信息提取必须按照它们在输入字符串中出现的顺序在控制台中打印(什么是棘手的，因为在Read循环中有3个模式需要判断)

import re

input_text = "quizas seria mejor ir de 06 00 am a 11 59 ya que me gusta viajar a esas horas" #example 1

finding loop:

    continue_comparing = True

    # 1) The least restrictive RegEx, not too restrictive but must be extracted by 2 substrings
    #    examples: "entre las 19hs y las 20 30", "entre las 18 y las 20", "entre la 1 y las 15hs"
    regex_1 = "(?:apartir de |de|entre |desde )\s*(?:las|la )\s*" substring_to_extract_1 "\s*(?:de la tarde|de la noche|de la mañana|)\s*(?:y las |y la |hasta las |hasta la |hasta )\s*" substring_to_extract_2 "\s*(?:de la tarde|de la noche|de la mañana|)"
    if (regex_2 == True and continue_comparing == True):
        print(repr(substring_to_extract_1))
        print(repr(substring_to_extract_2))
        continue_comparing = False
    
    # 2) The intermediate restrictive RegEx, but it must be indicated if it is "am" or "pm"
    #    examples:  "las 18:00am", "las 1800pm", "las 1800 p.m.", "las 08 00 am", "la 01 00 a.m.", "las 19 15 pm", "las 23 pm"
    regex_2 = "(?:las|la )\s*" substring_to_extract_1 "\s*(?:a.m.|a.m|am.|am|a m|p.m.|p.m|pm.|pm|p m)\s*(?:de la tarde|de la noche|de la mañana|)"
    if (regex_1 == True and continue_comparing == True):
        print(repr(substring_to_extract_1))
        continue_comparing = False

    # 3) The last and the most restrictive RegEx, it should only extract a substring like the first regex, but this requires that this substring be preceded by more things
    #    examples: "a las 17", "a las 6 y 15", "desde las 15 hs", "a las 15 y 45 hs", "hasta las 17 00", "antes de las 16:06"
    regex_3 = "(?:a eso de |a esas de |despues de |antes de |hasta |tipo |desde |apartir de |de |a )\s*(?:las|la )\s*" substring_to_extract_1 "\s*(?:de la tarde|de la noche|de la mañana|)"
    if (regex_3 == True and continue_comparing == True):
        print(repr(substring_to_extract_1))
        continue_comparing = False

在正则表达式模式中，我将提取数据的位置指示为substring_to_extract_1，但例如，对于第一个正则表达式，我认为类似于r'(\d{1,2}\s*(?::| )\s*\d{1,2}\s*(?:am|pm))'的内容可以工作.然后，我可以使用函数.groups()提取这些匹配

至于另外两个正则表达式，我不确定，因为它们在很大程度上取决于阅读循环的 struct .

一些可能要解析的输入字符串的示例:

Example 1:个

input_text = "quizas seria mejor ir de 06 00 am a 11 59 ya que me gusta viajar a esas horas"

在这种情况下，您必须逐个提取以下子字符串，并按出现的顺序打印它们...

output that I need:个个个个个

"de 06 00 am"   <--- was extracted by the second regex pattern
"a 11 59"       <--- was extracted by the third regex pattern

Example 2:个

input_text = "a eso de las 6 de la tarde o las 19 15 pm deberiamos estar alli, no crees? recuerda que desde las 15 hs ya empieza el evento, pero podemos estar alli antes de las 14 30 hs, aunque eso depende porque el show recien empezara entre las 15 hs y las 18pm"

output that I need:个个个个个

"de las 6 de la tarde"    <--- was extracted by the third regex pattern
"las 19 15 pm"            <--- was extracted by the second regex pattern
"desde las 15"            <--- was extracted by the third regex pattern
"de las 14 30"            <--- was extracted by the third regex pattern
"entre las 15"            <--- was extracted by the first regex pattern
"y las 18pm"              <--- was extracted by the first regex pattern

Example 3:个

input_text = "Hay que estar presentes entre las 19hs y las 20 30 hs, y seguro salimos a las 23 pm"

output that I need:个个个个个

"entre las 19"            <--- was extracted by the first regex pattern
"y las 20 30"             <--- was extracted by the first regex pattern
"a las 23 pm"             <--- was extracted by the second regex pattern

Example 4:个

input_text = "A las 19 salimos!! es importante llegar alla antes de las 20 30 hs"

output that I need:个个个个个

"A las 19"                <--- was extracted by the third regex pattern
"de las 20 30"            <--- was extracted by the third regex pattern

Example 5:个

input_text = "A las 19:30 salimos!! es importante llegar alla antes de las 20 30 hs, ya que a las 21: pm cierran algunos negocios, sin embargo el cine esta abierto hasta las 23:30 pm de la noche"

output that I need:个个个个个

"A las 19:30"                    <--- was extracted by the third regex pattern
"de las 20 30"                   <--- was extracted by the third regex pattern
"a las 21: pm"                   <--- was extracted by the second regex pattern
"hasta las 23:30 pm de la noche" <--- was extracted by the second regex pattern

我应该如何读取输入的字符串？因此，我应该如何构造允许我们在这些情况下判断模式的代码块？
