Q&A
###前提・実現したいこと
pythonのpandasを使用して移動平均を出したいのですが
'Series' object has no attribute 'rolling'となってしまいます。
--------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-112-570094cd89f4> in <module>() ----> 1 s.rolling(window=3, min_periods=3).mean() /Users/user/.pyenv/versions/anaconda3-2.4.0/lib/python3.5/site-packages/pandas/core/generic.py in __getattr__(self, name) 2244 return self[name] 2245 raise AttributeError("'%s' object has no attribute '%s'" % -> 2246 (type(self).__name__, name)) 2247 2248 def __setattr__(self, name, value): AttributeError: 'Series' object has no attribute 'rolling'
###該当のソースコード
python
1import pandas as pd 2s = pd.Series(range(0,10)) 3s.rolling(window=3, min_periods=3).mean()
