What is a the Python program you requested given the following:
I am working on the file "Lecture-widgets.ipynb".
The first task is:
The sizer.Add method has three arguments. The first one specifies the control to include in the sizer. The second one is a weight factor which means that this control will be sized in proportion to other ones. For example, if you had three edit controls and you wanted them to have the proportions 3:2:1 then you would specify these factors as arguments when adding the controls. 0 means that this control or sizer will not grow. The third argument is normally wx.GROW (same as wx.EXPAND) which means the control will be resized when necessary. If you use wx.SHAPED instead, the controls aspect ratio will remain the same.
If the second parameter is 0, i.e. the control will not be resized, the third parameter may indicate if the control should be centered horizontally and/or vertically by using wx.ALIGN_CENTER_HORIZONTAL, wx.ALIGN_CENTER_VERTICAL, or wx.ALIGN_CENTER (for both) instead of wx.GROW or wx.SHAPED as that third parameter.
You can alternatively specify combinations of wx.ALIGN_LEFT, wx.ALIGN_TOP, wx.ALIGN_RIGHT, and wx.ALIGN_BOTTOM. The default behavior is equivalent to wx.ALIGN_LEFT | wx.ALIGN_TOP.
One potentially confusing aspect of the wx.Sizer and its sub-classes is the distinction between a sizer and a parent window. When you create objects to go inside a sizer, you do not make the sizer the object's parent window. A sizer is a way of laying out windows, it is not a window in itself. In the above example, all six buttons would be created with the parent window being the frame or window which encloses the buttons -- not the sizer. If you try to create a visual element and pass the sizer as the parent window, your program will crash.
Once you have set up your visual elements and added them to a sizer (or to a nested set of sizers), the next step is to tell your frame or window to use the sizer. You do this in three steps:
python
window.SetSizer(sizer)
window.SetAutoLayout(True)
sizer.Fit(window)
The SetSizer() call tells your window (or frame) which sizer to use. The call to SetAutoLayout() tells your...
Can you write Python program for it?
