parsing Python-like code

Maybe use the ast module?

>>> import ast
>>> ast.parse('thing[4] = "banana"')
<_ast.Module object at 0x000002619ECBB1D0>
>>> pp(_)
ast.Module(
    body=[
        ast.Assign(
            targets=[
                ast.Subscript(
                    value=ast.Name(id='thing', ctx=ast.Load()),
                    slice=ast.Index(value=ast.Num(n=4)),
                    ctx=ast.Store()
                )
            ],
            value=ast.Str(s='banana')
        )
    ]
)
