Kirat[ad_1] You could use enumerate to iterate over the indices and values. Then use next to stop upon finding the first non-zero value. If StopIteration was thrown, the list contained no non-zero values, so do whatever error handling you’d like there. def first_non_zero(values): try: return next(idx for idx, value in enumerate(values) if value != 0) … Read more
[ad_1] The code is very inefficient because you find the thing, and then you turn around and find the thing again. So you end up looping multiple times. To make it more readable, I broke it up into parts. It also loops one time over the object to locate the items with children and the … Read more
[ad_1] I wrote this before the edit, so refer to your original code to see the differences. I added comments to explain what I did. One of the problems is the lack of {} around the code after the if statements. Without them only the first statement after the if is conditional. if(newLocation == 0) … Read more
[ad_1] What does this function do? It concatenates two strings, i.e. it’s doing the same as the standard strcat function. See https://man7.org/linux/man-pages/man3/strcat.3.html Assume the input is “Hello World”. Just when the function is called, some where in memory it looks like: String1: Hello\0 ^ | s1 String2: World\0 ^ | s2 Now this part while … Read more
[ad_1] You selected the correct regexp, you just have to quote it to use it in Python. You also need to call re.findall(), it’s not a string method. import re txt=”I refer to https://google.com and i never refer http://www.baidu.com” print(re.findall(r'(?<=https:\/\/)([A-Za-z0-9.]*)’, txt)) 1 [ad_2] solved Which of the following regular expressions can be used to get … Read more
[ad_1] You can do this with the Azure CLI which can be run in Powershell. You should be able to do this as a contributor with the az role assignment create command. Keep in mind that permissions with this command are granted at the container scope. Data Lake storage could be used to give folder … Read more
[ad_1] You could try a regex replacement: var text=”Hello. World… Lorem? Ipsum 123″; var output = text.replace(/([.?!])(?!.*[.?!]).*$/, “$1”); console.log(output); The replacement logic here says to: ([.?!]) match and capture a closing punctuation (?!.*[.?!]) then assert that this punctuation in fact be the final one .* match and consume all remaining text $ until the end … Read more
[ad_1] Is XSLT the right choice to interpret CDATA in a certain way and write to a file? Yes, CDATA is just a (part of a) text node and is processed as any other text node. Yes, the XSLT 2.0 xsl:result-document instruction is used to write to (possibly many different) file(s). .2. Use some sort … Read more
[ad_1] You’re using “…” instead of quotes “…”. Looks like code copied from a web page that transforms quotes into “fancy quotes” and pasted in a text file. Replace all occurrences of “ and ” with “. 4 [ad_2] solved sending an mail with attachment using php
[ad_1] 1) the count is number of milliseconds that are remaining for the timer to expire. This time seems to be relative to the previous timer and gets decremented every millisecond only for the topmost timer. Other timers’ count value remains untouched in the ISR. 2) because when second timer expires (its count goes down … Read more
[ad_1] To Implement FontAwesome, you will need to reference it on your page. This can be wherever you have refrenced other stylesheets (i.e. the header). In this example, I have used an online host (CDNJS) to provide the url. You can just copy and paste it. Otherwise, you can go to fontawesome’s website and sign … Read more
[ad_1] In 12c the FETCH clause allows you to do this select * from the_table order by value desc FETCH FIRST 1 ROWS WITH TIES; 4 [ad_2] solved SQL – How to select a row having a column with max value without using sub query in Oracle
[ad_1] Source you using is wrong multiple times. int a,b,c; a=b++, c++; first of all reading from uninitialized variables leads to UB, so you cannot predict what would be in a. Second, even if you would initialize b and c that expression is equal to: (a=b++), c++; to see behaviour predicted on that site you … Read more
[ad_1] The terminating condition a + b <= i is equivalent to b <= i – a which in turn (as Python for uses less than not less than or equal) would be b < i – a + 1. That means in Python you could write: for b in range((i – a) / 2, … Read more
[ad_1] You can run any program from Qt5 and capture it’s standard output using the QProcess class. The official documentation with examples is here: http://doc.qt.io/qt-5/qprocess.html So what I would do then is simply make a GUI with 2 QTextEdit widgets, one for the code and one for the compile/run output. Documentation for QTextEdit is here: … Read more
