character

问题 Below I was wondering if there might be a way to extract the columns Name and Groups from vc1 and vc2 and respectively paste them as the column names for objects AA , BB . For example, for MODEL 1 (below), my expected output of AA will be: plate_(Intercept) #: Name & Groups column from `vc1` Standard deviation 1.54 Proportion of Variance 1.00 Cumulative Proportion 1.00 sample_(Intercept) #: Name & Groups column from `vc1` Standard deviation 3.513 Proportion of Variance 1.000 Cumulative

问题 I am going to display Unicode dynamically, For example, I know "\U00020001" will display a character. (variable "standard_format" below). However, I can only show the whole string directly ( "\U00020001" ). I would like to know how can I show that string into a character. 回答1: If you write "\U0002B695" the whole string will be recognized as an escape sequence. In "\\U0002B695" however only \\ will be recognized as an escape sequence for \ . I don't know a way to build a string literal this

问题 Using the Python programming language, I'm having trouble outputting characters such as å, ä and ö. The following code gives me a question mark (?) as output, not an å: #coding: iso-8859-1 input = "å" print input The following code lets you input random text. The for-loop goes through each character of the input, adds them to the string variable a and then outputs the resulting string. This code works correctly; you can input å, ä and ö and the output will still be correct. For example, "år"

问题 I had a text content which is converted from a pdf file. There are some unwanted character in the text and I want to convert them to utf-8 characters. For instance; 'Artificial Immune System' is converted like 'Arti fi cial Immune System'. fi is converted like a one character and I used gdex to learn the ascii value of the character but I don't know how to replace it with the real value in the all content. 回答1: I guess what you're seeing are ligatures — professional fonts have glyps that

问题 I'm trying to get the length of a string in SQL (using Firebird version 2.x+). Whenever I select the length of a string it gives me the actual assigned maximum length of that string as opposed to getting the length of how many of the characters are taken in a record, as you can see here: as you can imagine, this does not help me, as I can't order by the length, since I'm trying to order by an attribute that has a constant length assigned. How would I achieve what I am trying to achieve? That

问题 I'm trying to write a little program where I ask the user to enter an email address. And then I verify if its a valid email address or not. Like "example@example.com" would be valid, but "example@@example.com.org" would be invalid. Here's my code, I have made it work to detect if there is an @ and . character in there, but I need to make sure it only appears once, and that the @ appears before the dot (.) import java.util.Scanner; public class email { public static void main(String args[]) {

问题 I would like to create a derived type containing allocatable character array components. However, when I try to allocate memory in subroutines, nothing happens. It may be more clear with the code example below: program test type t1 character(len=:), allocatable :: c(:) end type t1 type(t1) :: t call test_string1() call test_string2(t) contains subroutine test_string1() character(len=:), allocatable :: c(:) allocate( character(10) :: c(1) ) write(*, *) 'Size in string1: ', len(c) end

问题 I'm trying to make a program that counts all the vowels and all the consonants in a text file. However, if the file has a word such as cat it says that there are 3 consonants and 1 vowel when there should be 2 consonants and 1 vowel. #include <string> #include <cassert> #include <cstdio> using namespace std; int main(void) { int i, j; string inputFileName; ifstream fileIn; char ch; cout<<"Enter the name of the file of characters: "; cin>>inputFileName; fileIn.open(inputFileName.data());
