Python:每次出现 "clear"时，我都希望文本与列表相关联

Question

我正在尝试将我的测试框架与我的日志文件相关联，以确定哪些实例通过，哪些实例失败。为了更好地解释，这里有一个例子:我有一个列表:

data = ['F','P'] # first test pass, second test fail 

这是我的日志文件:

USER INPUT :  “clear”                   ------
SYSTEM RESPONSE: “Hello! How are you?”        | Fail
USER INPUT : “Good thank you”                 |
SYSTEM RESPONSE: "Okay"                 ------ 
USER INPUT : “clear”                    ------
SYSTEM RESPONSE: “Hello! How are you?”        |
USER INPUT : “I am good, Thank you!”          | Pass
SYSTEM RESPONSE: "Great!"                     | 
USER INPUT : “Good”                     ------

所以“清除”的每个实例都显示一个新日志，因此我希望第一个“清除”直到下一个清除发生与 P 相关联，我正在使用 html 构建代码，每当 P 出现时它都会绿色每次 F 出现时，代码为红色

到目前为止我所拥有的是:

            for line in lines :
                for i in cc:
                    if (data[i]== 'P'):
                        n = """<p style="color:green;>""" + line + '</p>'
                    else:
                        n = """<p style="color:red;>""" + line + '</p>'

我真的不确定结构。如何在每次出现“清除”时找到并为其分配特定颜色，直到下一个实例出现。请随时问我有关此的任何问题或进一步澄清!万分感谢!

您可以使用 re 根据 USER INPUT : "clear" 拆分日志文件:

log_file = """USER INPUT :  “clear”
SYSTEM RESPONSE: “Hello! How are you?”
USER INPUT : “Good thank you”
SYSTEM RESPONSE: "Okay"
USER INPUT : “clear”
SYSTEM RESPONSE: “Hello! How are you?”
USER INPUT : “I am good, Thank you!”
SYSTEM RESPONSE: "Great!"
USER INPUT : “Good”"""

import re
from pprint import pprint

groups = re.findall(r'USER INPUT.*?clear.*?(?:(?=USER INPUT :\s+\Wclear\W)|(?=\Z))', log_file, flags=re.DOTALL)
data = ['F','P']

style = {'P': '<p style="color:green;>', 'F': '<p style="color:red;>'}

html = ''
for d, g in zip(data, groups):
    for line in g.splitlines():
        html += style[d] + line + '</p>\n'

pprint(html)

这打印:

('<p style="color:red;>USER INPUT :  “clear”</p>\n'
 '<p style="color:red;>SYSTEM RESPONSE: “Hello! How are you?”</p>\n'
 '<p style="color:red;>USER INPUT : “Good thank you”</p>\n'
 '<p style="color:red;>SYSTEM RESPONSE: "Okay"</p>\n'
 '<p style="color:green;>USER INPUT : “clear”</p>\n'
 '<p style="color:green;>SYSTEM RESPONSE: “Hello! How are you?”</p>\n'
 '<p style="color:green;>USER INPUT : “I am good, Thank you!”</p>\n'
 '<p style="color:green;>SYSTEM RESPONSE: "Great!"</p>\n'
 '<p style="color:green;>USER INPUT : “Good”</p>\n')
