Concepts not extracted by the current parser

[jordanbarriap]

Many concepts are not being extracted by the current parser, here is an example with the missing concepts on comments per line:

try:
    f=open("test.txt","r")#file opening
    print(f.read())#file reading
    f.close()#file closing
    s="this is a test"
    sub=s.split()#string split and other built-in functions related to str
    for word in sub:
        print(word)
    aux=s[1:4]
    lst=[]#list creation
    lst.append(4)#list append
    lst.append(45)
    print(str(lst[0]))#typecasting and list access
    lst.pop(1)#list element removal
    del lst[0]
    lst2d = [[34,34,23],[12,2,1]]#2d list initialization
    print(float(lst2d[1][0]))#typecasting and 2dlist access
except:
    print("error")
    d={"a":5}#dict initialization
    print(d["a"])#dict access
    d["a"]=454

Concepts that are extracted:

Dict
Assign
Int
Del
Str
Slice
Delete
List
Attribute
Try
ExceptHandler
For
print

The parser uses only the AST and the mentioned thngs cannot be seen there - or at least not by the current logic in the parser.
