overwrite

I am using a Fortran 90 program that writes a file. The first line of this file is supposed to indicate the number of lines in the remaining file. The file is written by the program when a certain criterion is met and that can't be determined beforehand. Basically, I will know the total number of lines only after the run is over. I want to do it in the following manner: 1) open the file and write the first line with some text say, " Hello " 2) Write rows in the file as desired and keep a counter for number of rows. 3) Once the run is over and just before closing the file, replace the first

I am using Python csv module to read a csv file with every line being like: 2013-04-16 7:11:01,186744,3,2,2,1.89E-03 I then convert row[0] to unix time but then I want to replace the datetime with the unix time I just found for every row of my csv file import pymongo import datetime import re import csv import calendar X = [] OBD = [] Y = [] csv_in = open('FakeAPData.csv', 'rb') for row in reader: date = datetime.datetime.strptime(row[0], '%Y-%m-%d %H:%M:%S') datet = unicode(datetime.datetime.strptime(row[0], '%Y-%m-%d %H:%M:%S')) datett = tuple(int(v) for v in re.findall("[0-9]+", datet)) y =

Can anyone help me on how can I overwrite the excel file without prompting the users in VB.Net.. I have try this code but It doesn't work..

How to join and overwrite data appears to be a common request, but I have yet to find an elegant solution that applies to an entire dataset. (Note: to simplify the data, I will use only 1s and NAs for values and a small subset of columns, but in reality I have hundreds of columns with different values). I have one data table (d1) that has NA values in certain columns and rows. library(data.table) d1 = fread( "r id v1 v2 v3 1 A 1 1 1 2 B 1 1 1 3 C 1 NA NA 4 D 1 1 NA 5 E 1 NA 1")[, r := NULL] And I have another data table (d2) that consists of additional columns as well as data points missing

I have troubles with testing Model in CakePHP 2.0 and it seems the problem is on the model's constructor. public function __construct(){ parent::__construct(); $this->_pagi_cuantos = 2; } Even if I delete all its content, I still getting problems trying to run the test. Mark Story told me: if you have a constructor make sure you're overriding the constructor correctly. Failing to do so will cause errors like this. What do I wrong? why don't you look into the core code its open source after all: https://github.com/cakephp/cakephp/blob/2.1/lib/Cake/Model/Model.php#L653 so for all your models:

how do you overwrite the previous print in python 2.7? I am making a simple program to calculate pi. here is the code: o = 0 hpi = 1.0 i = 1 print "pi calculator" acc= int(raw_input("enter accuracy:")) if(acc>999999): print "WARNING: this might take a VERY long time. to terminate, press CTRL+Z" print "precision: " + str(acc) while i < acc: if(o==0): hpi *= (1.0+i)/i o = 1 elif(o==1): hpi *= i/(1.0+i) o = 0 else: print "loop error." i += 1 if i % 100000 == 0: print str(hpi*2)) print str(hpi*2)) It basicly outputs the current pi after 100000 calculations. how can I make it overwrite the previous

I have 3 tables: dentists, groups, and groupdentlink. Many dentists link to many groups through the groupdentlink table. So I'm trying to make a query where it will insert rows into groupdentlink (linking all dentists in the state with all the groups in the state) but only if those rows don't already exist. In a nutshell I want to add new rows without overwriting existing ones or duplicating them. So the intent of the query is something like: INSERT INTO groupdentlink (f_dent_id, f_group_id, f_schedule_id) VALUES ('$_POST[id]', '$groupid', '$scheduleid') WHERE NOT EXISTS ('$_POST[id]', '

The following code allows me to create a directory if it does not already exist. dir = 'path_to_my_folder' if not os.path.exists(dir): os.makedirs(dir) The folder will be used by a program to write text files into that folder. But I want to start with a brand new, empty folder next time my program opens up. Is there a way to overwrite the folder (and create a new one, with the same name) if it already exists? inspectorG4dget import os import shutil dir = 'path_to_my_folder' if os.path.exists(dir): shutil.rmtree(dir) os.makedirs(dir) cybertextron import os import shutil path = 'path_to_my
