for-loop

问题 Excel Image 1 From "Excel Image 1", I am pulling data into python of Column A and Column B. The goal is to sum the values of Column B, and see whether it is higher or lower than the given sum of 1500. If it is higher or equal to 1500, then there needs to be nothing done. But, if it is lower, then adjust the values that has the word "change" beside them, such that the calculated sum becomes 1500 or more. In our case, the sum is 700, which is lower than 1500. import xlrd excel = '/Users/Bob

问题 I have some data, that looks like the following: "Name","Length","Startpos","Endpos","ID","Start","End","Rev","Match" "Name_1",140,0,138,"1729",11,112,0,1 "Name_2",132,0,103,"16383",23,232,0,1 "Name_3",102,0,100,"1729",22,226,1,1 "Name_4",112,0,130,"16383",99,992,1,1 "Name_5",132,0,79,"1729",81,820,1,1 "Name_6",112,0,163,"16383",81,820,0,1 "Name_7",123,0,164,"1729",54,542,1,1 "Name_8",123,0,65,"16383",28,289,0,1 I have used the order function to order according to first "ID then "Start".

问题 I have been given the code for a tic tac toe game. I produced the code to check to see if the vertical will win and have tried to check the diagonal. I was able to check the primary diagonal but can't seem to determine how to check the secondary. I thought the code i have would work but it does not. The issue I am having begins on line 172 #include <stdio.h> #include <stdlib.h> // rand(), srand() #include <time.h> // time() // Size of the board (square) const int BOARD_SIZE = 3; // Symbols

问题 I have, what I believe to be a simple question with a simple answer that I cannot figure out for the life of me. I've created a plist that I'm trying to use to populate a MapView annotation with info. I've gone through some tutorials and this is the code I've decided to go with (running a loop). It wasn't showing the pins on the map so I decided to set up NSLogs at different point throughout the code to find the problem and if you look at the code below, it logs out "read1" but not "read2" so

However any of the searches after fisrt string are not achieving the objective. Objective The objective of the code is for it to find the string in the speficied row, then search that coloumn for values greater than zero, if so copy the whole row. Private Sub btnUpdateEntry_Click() Dim StringToFind As

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I have noticed similar repetition and trying to work around using a single for loop for this if I can to minimize the code length: I wouldn't need to use a switch case if I can form a loop instead? $returnNo variable starts at 5, each case multiplied by 2 then minus 1. where

问题 This program gives one value of Htm for each value of i. I want to display each value in turn by repeatedly pressing the calculate button. I want it to display the values for i=0 and then when i press the button it changes to i=1 and displays the values thus calculated. I know my question is a bit vague, but your help will be really appreciated..

问题 Similar questions have been asked already but none was able to solve my specific problem. I have a .R file ("Mycalculus.R") containing many basic calculus that I need to apply to subsets of a dataframe: one subset for each year where the modalities of "year" are factors (yearA, yearB, yearC) not numeric values. The file generates a new dataframe that I need to save in a Rda file. Here is what I expect the code to look like with a for loop (this one obviously do not work): id <- identif(unlist
