Classes

Annotation	An annotation, such as the `int` part of `x: int`
AssignExpr	An assignment expression, such as `x := y`
Attribute	An attribute expression, such as `value.attr`
AugLoad	The context of an augmented load. This is an artifact of the Python grammar which includes an AugLoad context, even though it is never used.
AugStore	The augmented store context, the context of var in var += 1
Await	An await expression such as `await coro`.
BooleanLiteral	A boolean named constant, either `True` or `False`
Bytes	A bytes constant, such as `b'ascii'`. Note that unadorned string constants such as `"hello"` are treated as Bytes for Python2, but Unicode for Python3.
Call	A call expression, such as `func(...)`
Del	The delete context, the context of var in del var
Dict	A dictionary expression, such as `{'key':'value'}`
Ellipsis	An ellipsis expression, such as `...`
Expr	An expression
ExprContext	A context in which an expression used
False	The boolean named constant `False`
Filter
FloatLiteral	A floating point numeric constant, such as `0.4` or `4e3`
FormattedValue	A formatted value (within a formatted string literal). For example, in the string `f'hello {world!s}'` the formatted value is `world!s`.
Fstring	A formatted string literal expression, such as `f'hello {world!s}'`
Guard	A guard in a case statement
IfExp	A conditional expression such as, `body if test else orelse`
ImaginaryLiteral	An imaginary numeric constant, such as `3j`
ImmutableLiteral	An immutable literal expression (except tuples). Consists of string (both unicode and byte) literals and numeric literals.
IntegerLiteral	An integer numeric constant, such as `7` or `0x9`
List	A list expression, such as `[ 1, 3, 5, 7, 9 ]`
Load	The load context, the context of var in len(var)
Name	A (plain variable) name expression, such as `var`. `None`, `True` and `False` are excluded.
NameConstant	A named constant, one of `None`, `True` or `False`
NegativeIntegerLiteral
None	The `None` constant.
Num	A numerical constant expression, such as `7` or `4.2`
Param	The parameter context, the context of var in def f(var): pass
PlaceHolder
Repr	A repr (backticks) expression, such as `value`
Set	A set expression such as `{ 1, 3, 5, 7, 9 }`
Slice	A slice. E.g `0:1` in the expression `x[0:1]`
Starred	A starred expression, such as the `rest` in the assignment `first, rest = seq`
Store	The store context, the context of var in var = 0
StringLiteral	A string constant.
Subscript	A subscript expression, such as `value[slice]`
True	The boolean named constant `True`
Tuple	A tuple expression such as `( 1, 3, 5, 7, 9 )`
Unicode	A unicode string expression, such as `u"\u20ac"`. Note that unadorned string constants such as “hello” are treated as Bytes for Python2, but Unicode for Python3.
Yield	A yield expression, such as `yield value`
YieldFrom	A yield expression, such as `yield from value`
