问题 I have some almost identical rows in a dataframe, see ex., the criteria to establish they are related are some variables "sel1,sel2" in this example, the other variables, var1 and var2, must be integrated by the following criteria: 1. discarding NA, or 2. discarding the shorter string (in var2 in the example). So, until now I have discarded the NA, but not find a way to at the same time discard the shorter string. The strings are complex and might have commas, spaces and several types of

问题 My aim is to find City that matches row from column general_text , but the match must be exact. I was trying to use searching IN but it doesn't give me expected results, so I've tried to use str.contain but the way I try to do it shows me an error. Any hints on how to do it properly or efficient? I have tried code based on Filtering out rows that have a string field contained in one of the rows of another column of strings df['matched'] = df.apply(lambda x: x.City in x.general_text, axis=1)

问题 I am trying to achieve the expand/contract functionality of table rows in JSF using core faces implementation. As answered in one of my earlier thread this is not straight forward to achieve in core faces implementation. So, I thought of using HTML + jQuery to achieve the functionality. I am calling the row with +/- gif as parent row and the rows that are to be expanded and contracted are its child rows. To make parent row aware of which child it needs to show or hide, I am making use of

问题 In PostgreSQL, what is the ROW() function used for? Specifically what is the difference between SELECT ROW(t.f1, t.f2, 42) FROM t; where f1 is of type int , f2 is of type text and CREATE TYPE myrowtype AS (f1 int, f2 text, f3 numeric); 回答1: You are confusing levels of abstraction. As other answers already point out, CREATE TYPE only registers a (composite / row) type in the system. While a ROW constructor actually returns a row. A row type created with the ROW constructor does not preserve
