Hi! I just started using Python yesterday and I have written a program that reads in a very large data file and rearranges the data so that it can be read into a different program. I am doing this for some engineering modeling simulations. I wanted to create an interface for it, so I started writing a GUI for Tk.
I do not understand how the even handlers work and I can't seem to hack it out by my internet findings. I would like to create 4 radio buttons (2 groups of 2) which provide the user with some options as well as an openfile and savefile. Then I want a button that based on the input of the other buttons, inserts the file names into my code and then "converts" the file using one of 4 codes based on those inputs. I will paste the code below.
I will also attach the necessary files (a smaller .csv file than I am using, however to save memory)
1). Conversion Code -- ftop.py
# This file is for converting Fluent .csv file to Polyflow.csv file in 3D
import psyco
psyco.profile()
import csv
import sys
import time
print "Running..."
secStart = time.time()
# Adds the header information for Polyflow
saveout = sys.stdout
temp = open("temp.dat","w")
temp.write("# \n")
temp.write("# \n")
temp.write("# \n")
temp.write("# \n")
temp.write("# \n")
temp.write("COORDINATES \n")
# Opens the Fluent .csv file for converting
file = open("quinn.csv","r")
first_line = file.next()
for line in file:
v = eval(line)
x = (v)
n,x,y,z,t = x
sys.stdout = temp
# Prints out the coordinate data
print '%8d' % n,";",'%E' % x,";",'%E' % y,";",'%E' % z
sys.stdout = saveout
# Adds the header information for the Temperatures
temp.write(" \n")
temp.write("TEMPERATURE \n")
# Opens the Fluent .csv file for converting again
file = open("quinn.csv","r")
first_line = file.next()
for line in file:
v = eval(line)
x = (v)
n,x,y,z,t = x
sys.stdout = temp
# Prints out the temperature data
print '%8d' % n,";",'%E' % t
sys.stdout = saveout
temp.close()
print "Elapsed time: %f sec." % (time.time() - secStart)2). The code I am trying to use to create the GUI-- radio.py
from Tkinter import *
from tkMessageBox import *
from tkColorChooser import askcolor
from tkFileDialog import askopenfilename
from tkFileDialog import asksaveasfilename
class gui(Tkinter.tk):
master = Tk()
dim = StringVar()
trans = StringVar()
w = Label(master, text="Please Select Model Dimensions:")
w.pack()
Radiobutton(master, text="2D", variable=dim, value='2D').pack(anchor=W)
Radiobutton(master, text="3D", variable=dim, value='3D').pack(anchor=W)
w = Label(master, text="Please Select Translation Options:")
w.pack()
Radiobutton(master, text="Polyflow to Fluent", variable=trans, value='ptof').pack(anchor=W)
Radiobutton(master, text="Fluent to Polyflow", variable=trans, value='ftop').pack(anchor=W)
# I want this to define the filename currently named "quinn.csv" in the conversion code
def callback():
filename = askopenfilename()
Button(text='Select source .csv File', command=callback).pack(fill=X)
# I want this to define the filename currently named "temp.dat" in the conversion code
def saveto():
destination = asksaveasfilename()
Button(text='Select destination', command=saveto).pack(fill=Y)
# I want this to be an if statement like...
# if dim == 3D and trans ==ftop3d.py (i know this is not correct, but I just wanted to give the general idea)
Button(text = "Convert",command = 'exit').pack()
mainloop()Please help me to understand what I am trying to do! Thanks for your help in advance!
