FWIW, I wrote a generic AST pretty printer for a personal compiler project (see
attached file). Perhaps it can be adapted to the Python AST.
## Example input ###############################
Program(procs=[Procedure(name='FACTORIAL', params=['N'], is_test=False,
body=Block(blocknum=0, stmts=[Assign(name=Output(is_bool=False),
value=Number(x=1)), Assign(name=Cell(i=0), value=Number(x=1)),
Loop(times=Id(name='N'), fixed=False, body=Block(blocknum=1,
stmts=[Assign(name=Output(is_bool=False),
value=BinOp(value1=Output(is_bool=False), op='x', value2=Cell(i=0))),
Assign(name=Cell(i=0), value=BinOp(value1=Cell(i=0), op='+',
value2=Number(x=1)))]))]))], calls=[])
## Example output ###############################
Program(
procs = [
Procedure(
name = 'FACTORIAL',
params = [
'N'
],
is_test = False,
body = Block(
blocknum = 0,
stmts = [
Assign(
name = Output(is_bool=False),
value = Number(x=1)

Assign(
name = Cell(i=0),
value = Number(x=1)
),
Loop(

fixed = False,
body = Block(

value1 = Output(is_bool=False),
op = 'x',
value2 = Cell(i=0)

Assign(

value = BinOp(
value1 = Cell(i=0),
op = '+',
value2 = Number(x=1)
