file-writing

问题 I am working on a script where it will breakdown another python script into blocks and using pycrypto to encrypt the blocks (all of this i have successfully done so far), now i am storing the encrypted blocks to a file so that the decrypter can read it and execute each block. The final result of the encryption is a list of binary outputs (something like blocks=[b'\xa1\r\xa594\x92z\xf8\x16\xaa',b'xfbI\xfdqx|\xcd\xdb\x1b\xb3',etc...] ). When writing the output to a file, they all end up into

问题 I am attempting to read in a JSON file in Golang, modifying this JSON file, and then creating a new JSON file/writing over this JSON file. I have seen several samples online, but can't seem to put two and two together to get the required result. I tried just making my own JSON str in GO and modifying that, but have still failed. package main import ( "encoding/json" "fmt" ) type Person struct { Name string Age int Details interface{} } func main() { //I created a simple Json structure here to

问题 I have Spark Dataframe with a single column, where each row is a long string (actually an xml file). I want to go through the DataFrame and save a string from each row as a text file, they can be called simply 1.xml, 2.xml, and so on. I cannot seem to find any information or examples on how to do this. And I am just starting to work with Spark and PySpark. Maybe map a function on the DataFrame, but the function will have to write string to text file, I can't find how to do this. 回答1: When

问题 I've written a code in Python that goes through the file, extracts all numbers, adds them up. I have to now write the 'total' (an integer) at a particular spot in the file that says something something something...Total: __00__ something something . I have to write the total that I have calculated exactly after the Total: __ part which would mean the resulting line would change to, for example: something something something...Total: __35__ something something . So far I have this for the

问题 I have a list that looks like this list_geo = [[5], ['Optimized energy: -39.726863484331 E_h'], ['C\t', '-1.795202\t', ' 0.193849\t', ' 0.019437'], ['H\t', '-0.728046\t', '0.337237\t', ' 0.135687'], ['H\t', '-2.044433\t', '-0.840614\t', ' 0.220592'], ['H\t', '-2.085087\t', ' 0.444715\t', '-0.993886'], ['H\t', '-2.323267\t', ' 0.834105\t', ' 0.714902']] I want to write this to file outputfile , and I tried to use with open(outputfile, "w") as output_file: output_file.write(list_geo) But this

问题 I am trying to write a struct to a file and read it back. The code to do so is here: #include <fstream> #include <iostream> #include <cstring> using namespace std; struct info { int id; string name; }; int main(void) { info adam; adam.id = 50; adam.name = "adam"; ofstream file("student_info.dat", ios::binary); file.write((char*)&adam, sizeof(info)); file.close(); info student; ifstream file2("student_info.dat", ios::binary); file2.read((char*)&student, sizeof(student)); cout << "ID =" <<

问题 I have a .txt file of words I want to 'clean' of swear words, so I have written a program which checks each position, one-by-one, of the word list, and if the word appears anywhere within the list of censorable words, it removes it with var.remove(arg) . It's worked fine, and the list is clean, but it can't be written to any file. wordlist is the clean list. newlist = open("lists.txt", "w") newlist.write(wordlist) newlist.close() This returns this error: newlist.write(wordlist) TypeError:

问题 I am using Windows 7, Python 2.7. I am trying to write to a text file with one file ID in one program that continues writing new data/numbers for several minutes. In a separate program, after the writing has begun, I am trying to read from the file that is being written in order to update and plot the data in the file. While the first program is writing the data, I am unable to read the data until it finishes. Here is some example code to illustrate my point: Program 1: import time fid = open

问题 I have a C server that writes packet data to an output file. The problem is I terminate the server in terminal using control c, and I've noticed that my output file is never finished writing to. Is there a way to make sure that my output file is completely written to before quitting? (I know I could just let the server run longer so I'm sure the data I want has been written, but I'm looking for an alternative method) Thanks Here's my code for reference. #include <stdio.h> #include <stdlib.h>

问题 I have a requirement where a zip file is sent to the ROR application after encoding it with Base64 encoding. I should decode it, save it as a zipfile and unzip it and do some operations. They are sending the zip file encoded data as a parameter called zip through POST method. Here, is what I have done in code. require 'rubygems' require 'zip/zip' require 'base64' def get_pdf encoded_data = Base64.decode64(params[:zip]) File.open("#{RAILS_ROOT}/zip_archive/zip_file.zip", "w") {|f| f.write
