I want to write a program such that I can enter in a pop-up entry box the stock symbol of my choice:
I know how to create an entry box in TKinter generally, but I don't know how to employ the .get() method here:
import datetime
import tkinter
from tkinter import *
import matplotlib.finance as finance
root = Tk()
E1 = Entry(root, bd=8)
E1.pack(fill=Y)
root.mainloop()
startdate = datetime.date(2013,1,1)
today = enddate = datetime.date.today()
ticker = 'I WANT THIS TO COME FROM THE ENTRY BOX '?
fh = finance.fetch_historical_yahoo(ticker, startdate, enddate)
You could use StringVar . For example
import datetime
import tkinter
from tkinter import *
import matplotlib.finance as finance
root = Tk()
# create a StrringVar
ticker_entry_var = StringVar()
E1 = Entry(root, bd=8, textvariable=ticker_entry_var)
E1.pack(fill=Y)
root.mainloop()
startdate = datetime.date(2013,1,1)
today = enddate = datetime.date.today()
# get value from the entry box
ticker = ticker_entry_var.get()
print(ticker)
Now, when you close the tk window, ticker will have the value from the stringvar.
