Go to Menu

```python from zipline.pipeline.filters import StaticAssets from zipline.pipeline import Pipeline from zipline.api import symbol, attach_pipeline, pipeline_output import pandas as pd

此處假設 assets 來自前面 bundle 的資料：

assets 已經定義，例如：assets = bundle.asset_finder.retrieve_all(sids)

def make_pipeline(): return Pipeline( columns = { "StaticAssets": StaticAssets( assets = assets[4:8] ) } )

def initialize(context): attach_pipeline(make_pipeline(), 'my_pipe')

def handle_data(context, data): pipe = pipeline_output('my_pipe') print("=" * 100) print(pipe)

def analyze(context, perf): pass

run_pipeline(make_pipeline(), pd.Timestamp("2019-01-02", tz='utc'), pd.Timestamp("2019-01-02", tz='utc'))
