问题描述

此问题与以下历史记录有关:链接

This question is with this history: Link

这是json格式的表:

Here is a json format table:

ID Title
19 I am doing great
25 [Must fix problem] Stomach not well
31 [Not-so-urgent] Wash cloths
498 [VERY URGENT] Pay your rent
517 Landlord wants you to pay your rent tomorrow
918 Girlfriend wants to help you to pay rent if you take her out
1000 [Always reproducible issue] Room partner dont want to pay any rent, he is out of cash

我做到了

在: selected_row_title = df.loc [df ['id'] == 4] [标题"]

In: selected_row_title = df.loc[df['id'] == 4]["title"]

输出:

[VERY URGENT] Pay your rent

现在，通过使用Python Pandas，我试图将函数编写为:

Now, by using Python Pandas, I am trying to write a function as:

get_matching_rows(selected_row_title )

输出

ID 498 has pay your rent 
ID 517 has pay your rent
ID 918 has pay rent
ID 1000 has pay rent

我一直在为此努力，我确实需要一些帮助，至少对如何实现这一目标提供了指导.感谢任何输入.

I have been tearing my hair out on this and I really need some help, atleast a guidance on how once can implement this. Appreciate any inputs.

推荐答案

我认为您可以使用

I think you can use str.replace with str.contains:

s = "[VERY URGENT] Pay your rent"

#replace all [] in column title
tit = df.Title.str.replace(r'[\[\]]', '')
print (tit)

0                                     I am doing great
1                    Must fix problem Stomach not well
2                            Not-so-urgent Wash cloths
