lapets / pydrogen Goto Github PK

Create a few working examples demonstrating how the library can be used to predict running times for a small subset of Python programs, including:

• explicit (i.e., numeric) prediction of steps the number of steps;
• symbolic prediction (i.e., as a polynomial) for functions that take a list of integers.

Identify any issues that arise from the use of the library (and add tickets as necessary).

Hi,

Has anyone met this error before?
When I used the sample code in document, AttributeError occurs.
AttributeError: module 'pydrogen' has no attribute 'Pydrogen'

The codes are:
import pydrogen
class Ty(pydrogen.Pydrogen):
def Statements(self, ss): return ss.post()[-1] # Last statement.
def Module(self, ss): return ss.post()
def FunctionDef(self, ss): return ss.post()
def Return(self, e): return e.post()

def True_(self): return 'Bool'
def False_(self): return 'Bool'
def BoolOp(self, es): return 'Bool'if frozenset(es.post()) == {'Bool'} else 'Error'
def Not(self, e): return 'Bool' if e.post() == 'Bool' else 'Error'

def Num(self, n): return 'Int'
def Add(self, e1, e2): return 'Int' if e1.post() == 'Int' and e2.post() == 'Int' else 'Error'
def Sub(self, e1, e2): return 'Int' if e1.post() == 'Int' and e2.post() == 'Int' else 'Error'
def Mult(self, e1, e2): return 'Int' if e1.post() == 'Int' and e2.post() == 'Int' else 'Error'
def USub(self, e): return 'Int' if e.post() == 'Int' else 'Error'

Thank you very much! Looking forward to the solution!

Hi,

When I execute the example, analysis.py. One error occurs.

TypeError: new() got an unexpected keyword argument 'items'

Should there be any change for the raw code?

Thank you very much!
