Description

You may access elements of python sequences using getitem or the shortcut _. This is equivalent to square brackets ([]) in Python. For example, this works for lists.

i1 : x = pythonValue "[1,2,3,4]"

o1 = [1, 2, 3, 4]

o1 : PythonObject of class list

i2 : getitem(x, 0)

o2 = 1

o2 : PythonObject of class int

i3 : x_1

o3 = 2

o3 : PythonObject of class int

It also works for dictionaries.

i4 : x = pythonValue "{'spam':1,'eggs':2}"

o4 = {'spam': 1, 'eggs': 2}

o4 : PythonObject of class dict

i5 : getitem(x, "spam")

o5 = 1

o5 : PythonObject of class int

i6 : x_"eggs"

o6 = 2

o6 : PythonObject of class int
