tkinter window empty , not displaying text

I'm running a simple tutorial on tkinter but for some strange reason my window comes up empty and not displaying the 'text=' whatsoever. I browsed all the related Qs (there are a few here) but none gave a solution.

The script executes without an error message but the window is not meant to be empty. Any advice would be appreciated as I feel like I explored all dead ends..

Here's the code:

import tkinter as tk
LARGE_FONT=("Verdana", 12)
class SeaofBTCapp (tk.Tk):
    def _init_(self,*args,**kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand = True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}
        frame = StartPage(container, self)
        self.frames[StartPage] = frame
        frame.grid(row=0, column = 0, sticky="nsew")
        self.show_frame(StartPage)


    def show_frame(self,cont):
        frame = self.frames[cont]
        frame.tkraise()


class StartPage(tk.Frame):
    def _init_(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text="Start Page", font=LARGE_FONT)
        label.pack(pady=10, padx=10)



app= SeaofBTCapp()
app.mainloop()

Python version: 3.5.2 |Anaconda 4.1.1 (64-bit)

Some other Qs on the subject discussing not using .frame and .pack together , I have tried deleting either .frame line or the .pack line but same result. Script runs w/o error but the window is empty.

Thanks!

As per Steven's answer:

You need two underscores for __init__ – Steven Summers

I was simply blind from staring at the lines looking for where it goes wrong.. Thanks.

The reason this code didn't work is because you did not display init correctly. You used _init_, which should have 2 underscores per each, e.g. __init__. Here's what you should have done:

import tkinter as tk
LARGE_FONT=("Verdana", 12)
class SeaofBTCapp (tk.Tk):
    def _init_(self,*args,**kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand = True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}
        frame = StartPage(container, self)
        self.frames[StartPage] = frame
        frame.grid(row=0, column = 0, sticky="nsew")
        self.show_frame(StartPage)


    def show_frame(self,cont):
        frame = self.frames[cont]
        frame.tkraise()


class StartPage(tk.Frame):
    def _init_(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text="Start Page", font=LARGE_FONT)
        label.pack(pady=10, padx=10)



app = SeaofBTCapp()
app.mainloop()

Also, you were using python 3.5 and this code works better in python 2.

Hope I could help :)
