How do I add my x and y coordinates into list from a text file?-CodePudding

hi im using python on jupyter notebook and i want to know how to add the x and y coordinates to a list from a text file containing coordinates into list.

The list is called citylist=[] filename is cities8 enter image description here

how do i append these coordinates into a list. Thank you so much for your time guys.

Assuming the data is separated by white spaces this can be done as follows:

with open('FILE_NAME_GOES_HERE', 'r') as f:
    data = f.readlines()

x_coordinates = []
y_coordinates = []

for line in data:
    _, x, y = line.split()
    x_coordinates.append(int(x))
    y_coordinates.append(int(y))

You can get the idea from here and make your own list in whatever format you want

First of all you have to read that file and split it using newline

citylist=[]
cities = open("cities8.txt", "r")
coordinates = cities.read().split("\n") # this will read and split file
cities.close() # close the file 
for city in coordinates:
    citylist.append(city.split(" ")[1:])

Now to print coordinates you can loop through the list

for i in citylist:
   print(f"X:{i[0]}, Y:i[1]")
