问题 This is the 3rd question on the same project: I was trying to grep string "Distance: " from "pairsAngles.txt" within each of over 2,000 subdirectories; the names of the subdirectories are obtained from a csv file.

问题 I really love the autofromat feature. I makes your code more readable and in case of JavaScript tells you, when there are synatcs errors (missing brackets etc.). However sometimes the formatting makes the code harder to read. e.g. when it puts a long array inizalisation into a single line. In that case I don't want him to format it, but rather leave it ofer multiple lines. E.g. define([ 'jquery', 'aloha', 'aloha/plugin', 'ui/ui', 'ui/scopes', 'ui/button', 'ui/toggleButton', 'ui/port-helper

问题 So I'm writing some code in Fortran that multiplies a square matrix by itself. But the matrix I have to multiply is in a file and I'm having some issues reading it into the program. I think its because the sample data is in the following format: 3 101 010 101 The first row is the dimension of the matrix, and each row is a now in the matrix, but there aren't spaces in between the entries. So I guess my question is how do I split up those rows as I read them into a 2d array? 回答1: Read in the

问题 I have a bunch of xml files, in each of these files there could be multiple variants (different language locale codes en-us, en-ca, en-gb etc.) I am new to powershell so I'm probably not understanding several concepts. I'm able to pull all this information but I'm having trouble outputting it in the format I want. I have tried using Out-File and have looked into Export-Csv but I'm just not able to get it to do what I want. Any help would be greatly appreciated. This is the format I want out

问题 I have a small question. I have this piece of code: #include <stdio.h> int main(){ printf("%d, %f, %d\n", 0.9, 10, 'C'); } And the output is this: 10, 0.900000, 67 But I would have expected: 0, 10.0, 67 But it looks like the printf searches for the corresponding type in the expressions (int and float are turned) Could anyone help me with this problem? Thank you very much! 回答1: But I would have expected: … When the format string does not match the types of the arguments in order, the behavior

Float { totalAmount += expensesAmount } 回答1: Try Follwoing : let entity:NSManagedObject = data?.object(at: i) as!

问题 I would like to covert a CSV to a set of JSON objects with Python, formatted in rows. I tried this script below, put together from a couple SO answers, but this formats this way: { key:'value' }, { key:'value' } // etc I would like to format this as: { key, 'value'}, { key, 'value'}, // etc I tried a few ways suggested here to insert a newline, but none worked so far. script below: import sys, getopt import csv import json CSV_PATH = 'path/file.csv' JSON_PATH = 'path/demo.json' csv_file = csv

问题 I'm still a beginner in Python, and I wanted to know why this : dict = {} dict[0] = '123' a = 0 if dict["{}".format(a)]["{}".format(a)] == '1': print('True') gives me a Key Error '0' but not this : dict = {} dict[0] = '123' if dict[0][0] == '1': print('True') Thanks in advance. 回答1: You're trying to compare the key 0 with "0". They are different. One is an integer and another is a string. 来源： https://stackoverflow.com/questions/24228161/key-error-0-with-dict-format
