问题 How do I return all the unique words from a text file using Python? For example: I am not a robot I am a human Should return: I am not a robot human Here is what I've done so far: def unique_file(input_filename, output_filename): input_file = open(input_filename, 'r') file_contents = input_file.read() input_file.close() word_list = file_contents.split() file = open(output_filename, 'w') for word in word_list: if word not in word_list: file.write(str(word) + "\n") file.close() The text file

问题 I have three input data files. Each uses a different delimiter for the data contained therein. Data file one looks like this: apples | bananas | oranges | grapes data file two looks like this: quarter, dime, nickel, penny data file three looks like this: horse cow pig chicken goat (the change in the number of columns is also intentional) The thought I had was to count the number of non-alpha characters, and presume that the highest count was the separator character. However, the files with

问题 I am newbie in Lucene, and I'm having some problems creating simple code to query a text file collection . I tried this example, but is incompatible with the new version of Lucene. UDPATE: This is my new code, but it still doesn't work yet. 回答1: Lucene is a quite big topic with a lot of classes and methods to cover, and you normally cannot use it without understanding at least some basic concepts. If you need a quickly available service, use Solr instead. If you need full control of Lucene,

问题 I want to read in data from a text file which is full of integers and have the program print those integers out to the screen while summing them. This shouldn't be hard, but I can't figure it out!!! Here is the extremely simplified text file: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 And here is my code that is supposed to work: import java.util.*; import java.io.File; import java.io.IOException; public class ReadFile { public static void main(String[] args) throws IOException {

问题 I have a simple piece of code that outputs console text to a text file in Java: PrintStream out = new PrintStream(new FileOutputStream("test2_output.txt")); System.setOut(out); However I require this text file to contain the error messages that is produced in the console but they are not included. How do I do this? 回答1: Add: System.setErr(out); at the end. 回答2: There is also a System.setErr() call to redirect stderr. 回答3: System.setErr(out) 回答4: You're currently redirecting the standard

问题 I'm trying to convert the data from a large number of PDF files to data frames in R. I've been converting the PDF files to .txt files using read.fwf(), but the issue is that the widths of all .txt files are not the same. Is there a way to determine the widths of the columns, or is there a way to use a function other than read.fwf()? I have a large number of files to convert and they all have different formats to begin with, so finding the specific column widths for each file is getting very

问题 I'd like to send the text content of a file over the serial port, over PuTTY. I know that extensions exists such as Xmodem and Zmodem, but they all use some checksum protocols to confirm that a file is sent over the port. However, my requirements are more simple. I'd like to simply send a bunch of text (in a file) over the serial port in Windows (under Linux this would be must more simple), but my preferred terminal program is PuTTY. Is this possible? Is there another terminal program that

问题 I have to write a textfile in VB6. I need to do it in appending and utf-8 encoded. I tried two solutions, one with "TextStream" and another one with "ADODB.Stream". The first one: Set fsoFile = fso.OpenTextFile(FileIn(fi), ForAppending, True) fsoFile.WriteLine "<tag>kkkjòòkkkkjlòlk</tag>" fsoFile.Close Works good in appending but how can I write it utf-8 encoded? The second one: Dim ST As ADODB.Stream Set ST = New ADODB.Stream ST.Mode = adModeReadWrite ST.Type = adTypeText ST.Charset = "UTF-8

问题 sample user id User Name U456 Mathew U457 Leon U458 Cris U459 Yancy U460 Jane and so on up to 500k. I need to read this text file and insert to MySQL in two columns say User ID and User Name. How do I do this in PHP? 回答1: LOAD DATA INFILE Example: NOTE: if you run this from Windows you need to escape the forward slashes in the file path. EXAMPLE: C:\\path\to\file.txt Looks like: C:\\\\path\\to\\file.txt Here is the query: LOAD DATA INFILE '/path/to/sample.txt' INTO TABLE `database_name`.
