Resampler.iter() not working (original) (raw)

Code Sample, a copy-pastable example if possible

for i, k in df.resample('W-MON'): print(i, k)

AttributeError Traceback (most recent call last) in () ----> 1 for i, k in df.resample('W-MON'): 2 print(i, k) 3 break

/xxx/lib/python3.5/site-packages/pandas/core/groupby.py in iter(self) 629 for each group 630 """ --> 631 return self.grouper.get_iterator(self.obj, axis=self.axis) 632 633 @Substitution(name='groupby')

AttributeError: 'NoneType' object has no attribute 'get_iterator'

Problem description

can't iterate the resampler's key and grouped dataframe

Expected Output

iterate the resampler's key and the grouped dataframe, now workaround

for key in df.resample('W-MON').groups.keys(): try: print(key, df.resample('W-MON').get_group(key)) except KeyError: continue

Output of pd.show_versions()
