问题 I am trying to group by a dataframe on one column, keeping several columns from one row in each group and concatenating strings from the other rows into multiple columns based on the value of one column. Here is an example... df = pd.DataFrame({'test' : ['a','a','a','a','a','a','b','b','b','b'], 'name' : ['aa','ab','ac','ad','ae','ba','bb','bc','bd','be'], 'amount' : [1, 2, 3, 4, 5, 6, 7, 8, 9, 9.5], 'role' : ['x','y','y','x','x','z','y','y','z','y']}) df amount name role test 0 1.0 aa x a 1

Excel creating multiply conditions ranking

由 淺唱寂寞╮ 提交于 2020-01-04 09:08:16
问题 I am trying to make a conditional ranking in this chart: On the right you can see the total score and ranking from the Match 1,2,3 (sum) on line A and C I have a tie score (3 points and both ranked at 2nd place), I'd like to to add a 2nd and 3rd conditions to determinate the final ranking. If there is a tie in score (both are in same ranking), then to determine who is 2nd and who is 3rd place I want to use the values from the XX's column first. The higher value will win the 2nd place and in a

100 <= x <= 150 as argument in if (), acting funny

由 爱⌒轻易说出口 提交于 2020-01-04 05:15:08
问题 I have an if statement followed by several else if statements. All of the if/else if statements have an argument structured something like this: if (100 <= x <= 149) //do this else if (150 <= x <= 199) //do that else if ...etc... However, for some reason only the first if statement ever gets executed. X can be 200 and only the first if statement will be recognized. I'm not sure why it isn't moving on to the next else if statement when X doesn't fit the argument of the preceding statement.

Conditional Formatting xlwt

由 半城伤御伤魂 提交于 2020-01-03 10:46:51
问题 I have seen some posts that say you can NOT perform conditional formatting using xlwt , but they were rather old. I was curious if this has evolved? I have been searching for about half a day now. Furthermore, if I con't write it directly from xlwt , can I create an .xls file containing a single cell with the conditional format I want and have xlrd read that format and paste it into the sheet I aim to produce then using xlwt ? 回答1: xlrd and xlwt still don't support conditional formatting .

Conditionally compiling entire namespaces - C#

由 让人想犯罪 __ 提交于 2020-01-03 07:29:13
问题 I was wondering if there is a way to conditionally compile entire namespaces in C#. Or am I left with having to explicitly decorate each source file within the namespace with the preprocessor directives to exclude it? In sub-versions of my application the code in various namespace is simply not required and I would like it excluded. Thanks in advance! 回答1: If your namespace is in a separate assembly which doesn't contain anything else you can use the Configuration Manager for your specific

由 别说谁变了你拦得住时间么 提交于 2020-01-02 19:47:13
问题 I have a Wordpress Memberships website that is built on WooCommerce with WooCommerce Memberships plugin to restrict certain pages to members only. Some of those pages are "drip-fed"... ie. Access to those pages opens 3 days after purchase, etc. I have set this up in WooMemberships. I am trying to simply do a PHP conditional check to see if the current user has access to a certain page. I have found this code piece in the docs: wc_memberships_is_post_content_restricted() However, I have been

Conditionally closing tag in Thymeleaf

由 做~自己de王妃 提交于 2020-01-02 18:27:08
问题 I need to conditionally close tag in my Thymeleaf template. Say, during iterating some collection of elements I have to wrap series of some of them into single <div> : <div>...element1, element2, element3...</div> <div>...element4...</div> <div>...element5, element6...</div> This could be archived if some way of conditionally tag closing would exist. But I can't obviously write </div th:if="..."> . If it would be jsp I could easily write something like: <%if (condition) {%></div><%}%> Any
