I actually have a big problem.
I already have a tkinter window and I want to open an other.

self.root.c = Canvas(tkroot, bg='black')
self.root.c.pack(fill=BOTH, expand=YES)
self.initialize()

self.imgclear = PhotoImage(file="img/clear.png")
self.root.title = Tkinter.Label(self.root, text="Enregistreur Orgue Sensoriel", bg="black", fg="white", font=("Helvetica", 16))
self.root.title.pack()

When I call my object I do:
rec = Gui_Record(self.tkroot)
rec.mainloop()
When I launch a single window it's okay. But when i add my new window to my parent window it happened that:

RuntimeError: maximum recursion depth exceeded while calling a Python object
I don't do recursion on my code.
I don't know what happened and didn't find anything in the web.
You are creating a class that inherits from Tk, but it also creates a new instance of Tk, and even though you don't show it you're also creating another root at some point (the object being passed in as tkroot) I'm not sure if that's the only problem, but it's definitely a problem.
Since this is a secondary window, you shouldn't be inheriting from Tkinter.Tk. Instead, inherit from Tkinter.Toplevel
You also have the problem that even though this creates a new window as a child of tkroot, some of the internal widgets are being created as children of tkroot so they won't appear in this window.
You also need to fix your imports -- you shouldn't be doing a global import from Tk and also importing Tk as a module.
You're likely going to have other problems. Tkinter doesn't work well with threads. I've heard that it sometimes works on linux, but in general you should never call any GUI function from any thread other than the one in which the widget was created.

What am I doing wrong?
You are trying to create two instances of Tk window. You can't do that. If you want second window or pop-up window you should use Toplevel() widget.
Also, self doesn't mean anything in this context. Using the widget's image property would be better to keep a reference.
import tkinter
ssw = tkinter.Tk()
def six():
toplvl = tkinter.Toplevel() #created Toplevel widger
photo = tkinter.PhotoImage(file = 'American-Crime-Story-1.gif')
lbl = tkinter.Label(toplvl ,image = photo)
lbl.image = photo #keeping a reference in this line
lbl.grid(row=0, column=0)
def base():
la = tkinter.Button(ssw,text = 'yes',command=six)
la.grid(row=0, column=0) #specifying row and column values is much better
base()
ssw.mainloop()

Do you know where is the problem?
The fault is that you don't have an __init__ method in the class CalendarDialog. So just rename the body method to __init__. Now you have initialized the instance every time one is made and a pack() method is defined.
I also encountered this problem putting a ttkCalendar into a Dialog box.
I suspect the author of this post "borrowed" the same code for building a calendar as I did:
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwiWgYWKsJ3nAhVKl3IEHYrhCU8QFjABegQICBAB&url=https%3A%2F%2Fsvn.python.org%2Fprojects%2Fpython%2Ftrunk%2FDemo%2Ftkinter%2Fttk%2Fttkcalendar.py&usg=AOvVaw0ifTox4EI7CtBFWlRYD_m9
There are two problems I found using this code to create a Calendar object and placing it into a Dialog box.
The first one causes the traceback as shown in the post. The fix is to modify the ttkcalendar.py file to pack the calendar when it is created, not after it is created using the pack() function.
Here is the diff:
102c102
< self._calendar = ttk.Treeview(show='', selectmode='none', height=7)
---
> self._calendar = ttk.Treeview(self, show='', selectmode='none', height=7)
109c109
< self._calendar.pack(in_=self, expand=1, fill='both', side='bottom')
---
> self._calendar.pack(expand=1, fill='both', side='bottom')
Once you make this change, the calendar will appear in the dialog box. However, your problems are not yet done. Another exception occurs when trying to set the minimum size of the calendar:

I am writing my own Library, so I can use some functions later faster and easier. At the moment, I am working with python's GUI Library Tkinter. (from tkinter include *)
def guiFrameNew(title, width, height):
guitmp = Tk();
return guitmp;
def guiTextboxReadonlyNew(frame, width, text):
guitmp = Entry(Frame, state="readonly", textvariable=text, width=width);
guitmp.pack();
return guitmp;
def guiFrameRun(frame):
frame.mainloop();
This all is in one file (file_one.py).
In an other file (file_two.py) i included this file:
include file_one as f
Code in file_two is:
main = f.guiFrameNew("Test", 0, 0);
main_tbro = f.guiTextboxReadonlyNew(main, 20, "Some Text");
f.guiFrameRun(main);
Yes, I know that I don't need the values Title, width, height in def guiFrameNew because the function does not create a frame.
After I started the file_two.py the python Interpreter says:
> File "file_two", line 5, in <module>
> main_tbro = f.guiTextboxReadonlyNew(main, 20, "Some Text"); File "/Users/MyUsername/Documents/py/file_two.py", line 190, in

I don't know why, because the function def guiTextboxReadonlyNew(...) is similar to the function
def guiTextboxNew(frame, width):
guitmp = Entry(frame, width=width);
guitmp.pack();
return guitmp;
and def guiTextboxNew(...) works!
What is wrong in my file?
Assumming by include you mean import (which is really the case, since you are able to import the module file_one).
The Entry() takes a frame object as the first argument, not the Frame class. You should do -
def guiTextboxReadonlyNew(frame, width, text):
guitmp = Entry(frame, state="readonly", textvariable=text, width=width)
guitmp.pack()
return guitmp
Also, there is not really any need for ; (semi-colon) in python after statements.

Please help!Answers will be appreciated!
You need to call super class' __init__ method:
class myproject(Tkinter.Tk):
def __init__(self, parent, master):
Tkinter.Tk.__init__(self) # <----
self.button()
self.checkbox()
self.radiobutton()
...
In addition to that, there's undefined variables CheckVar2, var.
I'm new to python. I'm trying to open a dialog box to get a value from within a widget that does a list of other staff allready.

So as may be apparent to you, I'm importing dataset with an Import button, executing some analysis in another code through a button called Execute, and then showing some graphs.
What I wanted was to open a pop up kind of window on click of "Execute" button that will input a value. But I'm getting the following error:

I've no idea what to do. Please help.
When you create the toplevel widget, you are passing self as the first argument. Tkinter requires that this be a parent widget. However, in your code self does not represent a widget.
In your specific case you want to pass in self.mymaster rather than self:
top = self.top = Tkinter.Toplevel(self.mymaster)
Use Tkinter.Toplevel() instead of Tkinter.Toplevel(self)
