we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined

In this example, power() gets the value of exponent from the outer function, generate_power(). Here’s what Python does when you call generate_power(): Define a new instance of power(), which takes a single argument base. Take a snapshot of the surrounding state of power(), which ...
Parameters are specified within the pair of parentheses in the function definition, separated by commas. When we call the function, we supply the values in the same way. Note the terminology used - the names given in the function definition are called parameters whereas the values you supply ...
Finally, note that in the earlier example, you executed the inner functions within the parent function—for example, first_child(). However, in this last example, you didn’t add parentheses to the inner functions, such as first_child, upon returning. That way, you got a reference to ...
This implementation provides a clean and reliable way of calling any needed cleanup functionality upon normal program termination. Obviously, it’s up tofoo.cleanupto decide what to do with the object bound to the nameself.myhandle, but you get the idea. ...

The grid() method is used to specify the relative layout (position) of the label within its containing frame widget, similar to how tables in HTML work. A button widget is then created, and placed to the right of the label. When pressed, it will call the destroy() method of the root...
