Ultimately, this is because some base-10 numbers (like 0.9) cannot be represented in base 2 in a finite number of digits, just like the fraction 1/3 cannot be represented in base 10 in a finite number of digits (you get 0.333…). 0.9 converted to base 2 is 0.1110011001100…, and this binary representation gets truncated such … Read more
You can use ruby ranges for this: list = (1..num).to_a To print an array use the inspect method, i.e. puts list.inspect 3 solved Send in a number and return an array in Ruby [closed]
Your question is very broad and ambiguous, but I will attempt to provide an answer to what I think you’re looking for: Assuming you already have an .xap file (that is, the file produced by building a Silverlight Application in Visual Studio 2010), you can simply embed it in any HTML or ASPX page by … Read more
How about: \d{1,2}(?:[.,]\d{1,2})? explanation: \d{1,2} : one or two digits (?: : start non capture group [.,] : . or , \d{1,2} : one or two digits )? : end group, optional 1 solved Custom regular expression [closed]

You’ve got <?php ?> inside existing PHP code. You cannot nest <?php ?>. Since you are using double quotes, simple variables like $kinsource will be interpolated but the function call to get_bloginfo() will have to be concatenated in. Switch all other double quotes inside the string to single quotes. $return .= “<a href=”https://stackoverflow.com/questions/9354628/$kinsource” class=”lightbox” rel=”pics”><img … Read more
A simple solution: int[] card1 = nums.OrderBy(it => Guid.NewGuid()).Take(6).ToArray(); Ordering the original array by a new guid should give you a decent approximation of randomness while avoiding the requirement to explicitly guard against duplication. Then you just take the first 6 results. Warning: The random-like behaviour of ordering by guid is an implementation detail of … Read more
Use a regular expression. str_replace will only replace static values. $RAMBOX = ‘hardwareSet[articles][123]’; $Find = ‘/hardwareSet\[articles\]\[\d+\]/’; $Replace=”hardwareSetRAM”; $RAMBOX = preg_replace($Find, $Replace, $RAMBOX); Output: hardwareSetRAM The /s are delimiters. The \s are escaping the []s. The \d is a number. The + says one or more numbers. Regex101 Demo: https://regex101.com/r/jS6nO9/1 If you want to capture the … Read more
import pandas as pd sys.path.insert(0, “/usr/lib/python2.7/site-packages”) This line contains two statements. Split them into two lines: import pandas as pd sys.path.insert(0, “/usr/lib/python2.7/site-packages”) Or, if they must be in one line, separate them with semicolon (highly not recomended!!!): import pandas as pd; sys.path.insert(0, “/usr/lib/python2.7/site-packages”) 1 solved Python returns “SyntaxError: invalid syntax sys module” [closed]
When you create an instance of a subclass JVM creates instances of all superclasses (including Object). If you don’t call constructor of parent class yourself JVM will do it for you if parent class has noarg constructor or you will have a compilation error if your parent class doesn’t have noarg constructor and you don’t … Read more
Try this: from io import StringIO csvtext = StringIO(“””1 1 1 1 1 2 3 4 4 4 4″””) data = pd.read_csv(csvtext, sep=’\n’, header=None) data.to_csv(‘out.csv’, index=False, header=False) #on windows !type out.csv Output: 1 1 1 1 1 2 3 4 4 4 4 2 solved converting a text file to csv file with out index
Declare the linkedlist first, then add to it in the constructor. public static LinkedList list = new LinkedList(); public LibraryUser() { count ++; // add to the list list.add(this); } 2 solved i want to add an object to the linked list
[&](int n) {} means that in the lambda block you capture every variable from the scope by reference in contrast for example to [=](int n) {} where you have an access by value. You could also specify excactly what variable you need to be passed by reference or by value [&a, b](int n) {} PS. … Read more
If you want to check for substrings also i.e azy in lazy, you need to check each word from words is in each substring of message: message = “The quick brown fox jumps over the lazy dog” words = [“the”,”over”,”azy”,”dog”] print(sum(s in word for word in set(message.lower().split()) for s in words)) 4 Or simply check … Read more
