One way to find the shortest distance between a series of surface (x, y) points is to let Python module itertools find the non-repeating combinations of point pairs. Now you can apply the Pythagoras' theorem to find all the distances and the minimum distance.

Knowing the longitude and latitude coordinates of two cities you can calculate the distance between them. Use the code in https://www.daniweb.com/software-development/python/code/490561/postal-code-zips-and-location-python to find the coordinates.

Hello, I have the following problem: Entering coordinates of points on a plain with keyboard (as rows x,y). Analysing this coordinates. Replacing coordinates in vector (point - structure data type). Then calculating distance from the first point to all another points. I've written the code of this problem using arrays …

If I input an arbitrary amount of points [x1,y1].....[xn,yn] into a function I need to somehow return/print the shortest distance between all of the points. I understand how to find the distance between two points (fairly easy and straight forward), but how do I take an arbitrary amount of points …

How do i implement levenshtein disance on records in a database table using python? I know how to connect python with database, coding in python may not be problem, and I also have the records in a database table. The problem is how do i make it work. Below is …

So I've been working on a page to locate shops based on zip code and mile distance. I used this tutorial as a walk-through http://htmlcampus.com/build-a-zip-code-store-locator-application-in-php/ Now I've changed a couple of things like the mySQL table is called locations instead of zip_codes. I've tested it and it connects to the …

Hi all. I'm having trouble with this simple Java program. When I compile it, numerous errors would happen. I put in let's say 50 miles for the speed of the car and 2 hours for the traveling hours. I run it and it you see this: Hours Distance Traveled --------------------------------- …

Hi, basically ive been trying to write code to work out where the nearest station for a person is based on their current location. I did have it working to display nearest station name and distance from that station but something went wrong I must have accidently deleted something or …

Problem: solve the following Source of SHORTEST DISTANCE path of A,B,C,D,E,F,G. I already did link the strings of dots of ABCDEFG and made a polygon which is the other objectives, my only problem now is calculating the source of the shortest distance part of A,B,C,D,E,F,G. Am using net beans. Guys …

i see this code in this thread, i want to know how to get input by user or from file in this code. for example this list how to use it as input in this code. i don't know how to modify and how to use it. Daniweb thread reference …

Dear Frendz, How to find distance between two latitude and longitude points using php.

Could someone give me help on how to simplify this? Trying to write code to solve this equation: Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2) I subbed a,b,c as the second set of coords. Im probably using too many vars as weel but im …

hello. I am quite new in python so i have a question. I have a csv file in which i have names of 30 cities and their coordinates(lat and long). i want to generate a distance matrix for these cities. How can i do this ?

Hi.. how to calculate distance between two points.. each point have a coordinates (x,y). please help..

Hello Everyone, I have a list of digits. What is the most efficient way to count the number of tokens between two known digits? Here is what I came up with: [CODE] def dis(l, a1, a2): i1 = l.index(a1) i2 = l.index(a2) distance = i2 - i1 - 1 return …

Hi I have several PCs and want to connect them on a home network. It makes sense to upgrade to a gigbit system. The trouble is how far may I locate a pc from the keyboard, mouse, and display?
