问题 I am trying to find the start and stop index of numbers > 0 in list cross = [7,5,8,0,0,0,0,2,5,8,0,0,0,0,8,7,9,3,0,0,0,3,2,1,4,5,0,0,0,7,5] I am getting the indexes of values > 0 followed by index of value = 0. Desired output: (0 2),(7 9), (14 17).. Actual output: (2 3), (7 8).. My code cross = [7,5,8,0,0,0,0,2,5,8,0,0,0,0,8,7,9,3,0,0,0,3,2,1,4,5,0,0,0,7,5) for i in range(0,len(cross)): if cross[i]==0: while(cross[i-1]>0): i+=1 print(i-1,i) 回答1: How about using some flags to track where you

问题 I'm trying to create a jQuery function that counts the character length of each anchor tag & applies a class if the character count is greater than "5". Additionally, if the character count is greater than 7 (4 + 3) then apply a different class. This is where I got to (JSFIDDLE: http://jsfiddle.net/2mg3q/): HTML <div id="global-nav"> <ul id="nav"> <li><a href="#">One</a></li> <li><a href="#">Item5</a></li> <li><a href="#">Item with11</a></li> <li><a href="#">One</a></li> </ul> </div> CSS #nav

问题 I am new to VBA programming, and I need some help writing a simple macro in Excel 2010. I need to search for a text string in Column A (the exact text I'm searching for is not specified ) and if that string is found within the cell, cut and paste that cell's entire row into another sheet in the workbook and then delete the empty rows in the original sheet. I searched the forum a bit and found some code examples that almost got me where I wanted to get but not quite. 回答1: OK. I used the

问题 How do i load my React toolbar component conditionally on state change? constructor(props) { super(props); this.state = { currentpagenum: 0, }; } render(){ return( <View> {this.state.currentpagenum!==0 ? this.getToolbar(): null;} </View> ); } getToolbar(){ return( <ToolbarAndroid /> ); } 回答1: Looks like you got a typo error you added ; after null this is unneeded also you can get rid of the getToolbar function Instead try: constructor(props) { super(props); this.state = { currentpagenum: 0, }

问题 So I have done some research and am close to an answer, but what I am trying to do may not be possible with CSS alone which I really hope it is. The end goal is to set the width of the elements with a class of bricks to 90% if the width of the element with the id of primary is 915 or less. html snippet: <div id='primary'> <div class='bricks'> <p>div-1</p> </div> <div class='bricks'> <p>div-2</p> </div> </div> css snippet: #primary{ width:100%; } .bricks{ width:45%; } @media only screen and (

问题 I would like to count how many rows there are per type if they meet the condition x == 0 . Sort of like a group by in SQL Here is an example of the data type x search 0 NULL 0 public 0 search 1 home 0 home 1 search 0 回答1: I am assuming that you want to find the number of rows when a particular condition (when a variable is having some value) is met. If this is the case, then I suppose you have "x" as a variable represented in a column. "x" can take multiple values. Suppose you want to find

问题 So I didn't see a question here that really answers this question. It's kinda a newbie question about linq but I would like to know if it would be possible to convert the following sql query (built using C#) into a linq query: public void DoSomeQuery(bool whereCriteria1, bool whereCriteria2) { string sqlQuery = "SELECT p.*"; string fromClause = " FROM person p"; string whereClause = " WHERE "; if (whereCriteria1) { fromClause += ", address a"; whereClause += " p.addressid = a.addressid and a

问题 This is not about the API. This is about using Mailchimp and setting conditional merge fields in the backend of Mailchimp when building a campaign. So this question is about how Mailchimp works rather than about integrating Mailchimp via an API or something similar. (You're still here? Great! :-) I'm trying to use a date field to show conditional content. I have 3 people in my test mailing list, one with birthday 1/1/1960, one with 1/1/1970 and one with 1/1/1980. I've set up an email with

问题 I have found myself doing a "conditional left join" several times in R. To illustrate with an example; if you have two data frames such as: > df a b 1 1 0 2 2 0 > other.df a b 1 2 3 The goal is to end up with this data frame: > final.df a b 1 1 0 2 2 3 The code I've been written so far: c <- merge(df, other.df, by=c("a"), all.x = TRUE) c[is.na(c$b.y),]$b.y <- 0 d<-subset(c, select=c("a","b.y")) colnames(d)[2]<-b to finally arrive with the result I wanted. Doing this in effectively four lines

问题 I'm trying to calculate a running count (i.e., cumulative sum) that is conditional on other variables and that can reset for particular values on another variable. I'm working in R and would prefer a dplyr -based solution, if possible. I'd like to create a variable for the running count, cumulative , based on the following algorithm: Calculate the running count ( cumulative ) within combinations of id and age Increment running count ( cumulative ) by 1 for every subsequent trial where
