I have been using the following snippet: library(data.table) filepaths <- list.files(dir) resultFilename <- “” for (i in 1:length(filepaths)) { content <- fread(filepaths, header = FALSE, sep = “,”) ### some manipulation for the content results <- content[1] fwrite(results, resultFilename, col.names…
I ran the code in gdb, it runs perfectly. It opens the file, gets the < cr > character from stdin, writes that to the first line which wipes out the first line, then tries to read the first line…
Using Python 2.7.6 this works for me: filename = raw_input(“File Name: “) with open(filename, ‘r+’) as f: text = f.read() f.seek(0) f.write(text.upper()) f.truncate() 2 solved Python converting text file to all caps
You can build a list of lines skipping the digit ones this way : lines = [line for line in data.splitlines() if not line.strip().isdigit()] assuming data is your text file content. 1 solved How to extract a line from text…
Your question seems to have two main parts to it: how do I get inputs in Python and how do I save data to a file in Python. To get input from the terminal: >>> data = input(‘Input: ‘) >>>…
In order to connect to other computers in Java, you should use Sockets, and define your own Protocol (Basically, your protocol would consist on a handshake, and some way on asking the other part of the connection to send the…
What you want is to use a BufferedReader instance to read from the file, and parse each line that you get from it. For example: try { BufferedReader reader = new BufferedReader(new FileReader(“filename”)); String line; while ((line = reader.readLine()) !=…
I’ve created a basic class for you that will save the wins to a text file and retrieve them from a text file. import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; import java.util.Scanner; public class WinsFileManager { String path = System.getProperty(“user.home”).replace(“\\”, “\\\\”)…
Try this, if you want to save username password in the same file string fileName = textBox1.Text + “.txt”; System.IO.File.WriteAllText(@”C:\\Users\\User\\Documents\\1ClickData\\ID\\” + fileName, “Username=”+textBox1.Text+” Password=”+textBox2.Text); or if you want to save username and password in separate file //for username string fileName1…
The problem is that you are over-writing the value of namelist and scorelist with each pass through the loop. You need to add each item to a list. Adding a sequential list of items to a list is usually done…
// Retrieve 10 lines from Somefile.txt, starting from line 1 string filePath = “C:\\Somefile.txt”; int startLine = 1; int lineCount = 10; var fileLines = System.IO.File.ReadAllLines(filePath) .Skip((startLine-1)) .Take(lineCount); solved Read txt file from line to line to list?
import java.io.BufferedReader; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; public class Read_Text_File { public static void main(String[] args) { System.out.println(getValues()); } public static ArrayList<String> getValues() { FileInputStream stream = null; try { stream = new FileInputStream(“src”); }…
Similar to previous answer but with the following suggestions Initialize longest and shortest. Ignore case when comparing. Could still do this with SequenceEqual instead of comparing strings. May not be needed if you know you won’t be comparing Anna to…
Your were breaking out of the loop: (Btw i added a with statent for opening the file in a more pythonic way) order = input(“Please enter the name of the product you wish to purchase\n”) with open(“barcode.txt”,”r”) as myfile: details=myfile.readlines()…
