The value of an entry widget can be obtained with the get method of the widget:
name_entry = tk.Entry(parent)
...
name = name_entry.get()
Optionally, you may associate an instance of a StringVar, and retrieve the value from the StringVar rather than from the widget:
name_var = tk.StringVar()

Modules can be required without using relative paths by putting them in a special directory called node_modules.
For example, to require a module called foo from a file index.js, you can use the following directory structure:
index.js
\- node_modules
\- foo
|- foo.js
\- package.json

Here is an example:
my_array = array('i', [1,2,3,4,5])
c=[11,12,13]
my_array.fromlist(c)
# array('i', [1, 2, 3, 4, 5, 11, 12, 13])
So we see that the values 11,12 and 13 were added from list c to my_array.
index() returns first index of the matching value. Remember that arrays are zero-indexed.
my_array = array('i', [1,2,3,4,5])
print(my_array.index(5))
# 5
my_array = array('i', [1,2,3,3,5])
print(my_array.index(3))
# 3
Note in that second example that only one index was returned, even though...
This method provides you the array buffer start address in memory and number of elements in array. Here is an example:
my_array = array('i', [1,2,3,4,5])
my_array.buffer_info()
(33881712, 5)
count() will return the number of times and element appears in an array. In the following example we see that the value 3 occurs twice.
my_array = array('i', [1,2,3,3,5])
my_array.count(3)
# 2
You are able to append a string to a character array using fromstring()
my_char_array = array('c', ['g','e','e','k'])

An interface is declared like a class, but without access modifiers (public, private, ...). Also, no definitions are allowed, so variables and constants can't be used.
Interfaces should always have an Unique Identifier, which can be generated by pressing Ctrl + Shift + G.
IRepository = interface
