我偶然發(fā)現(xiàn)了一個我不理解或找不到解決方案的問題。我鍵入的代碼在我的 Jupyter Notebook 中運行完美，但在我使用 PyCharm 時出現(xiàn)錯誤。我在 PyCharm 中輸入了這些代碼：df_ticker.loc[df_ticker['Red'] == True, 'Value'] = df_ticker['Open'] - df_ticker['Close']df_ticker.loc[df_ticker['Red'] == False, 'Value'] = df_ticker['Close'] - df_ticker['Open']單獨使用這些代碼并打印它們的值是成功的。H但是，當(dāng)與這些代碼行匹配時：for i in range(1, len(df_ticker)):if df_ticker.Close[i] > df_ticker.Close[i-1] and df_ticker.Red[i] == False and \        df_ticker.Value.round(decimals = 0)[i] >= df_ticker.Value.round(decimals = 0)[i-1] \        and not df_ticker.Close[i-1] >= df_ticker [i-2]:    rise.append(df_ticker.Close[i])它返回此錯誤：Traceback (most recent call last):  File "/Users/benjaminwong/PycharmProjects/Yahoo Finance project/venv/lib/python3.8/site-packages/pandas/core/indexes/base.py", line 2889, in get_loc    return self._engine.get_loc(casted_key)  File "pandas/_libs/index.pyx", line 70, in pandas._libs.index.IndexEngine.get_loc  File "pandas/_libs/index.pyx", line 97, in pandas._libs.index.IndexEngine.get_loc  File "pandas/_libs/hashtable_class_helper.pxi", line 1675, in pandas._libs.hashtable.PyObjectHashTable.get_item  File "pandas/_libs/hashtable_class_helper.pxi", line 1683, in pandas._libs.hashtable.PyObjectHashTable.get_itemKeyError: 5The above exception was the direct cause of the following exception:Traceback (most recent call last):  File "/Users/benjaminwong/PycharmProjects/Yahoo Finance project/Rise_Finder 2.py", line 29, in <module>    and not df_ticker.Close[i-1] >= df_ticker [i-2]:  File "/Users/benjaminwong/PycharmProjects/Yahoo Finance project/venv/lib/python3.8/site-packages/pandas/core/frame.py", line 2899, in __getitem__    indexer = self.columns.get_loc(key)  File "/Users/benjaminwong/PycharmProjects/Yahoo Finance project/venv/lib/python3.8/site-packages/pandas/core/indexes/base.py", line 2891, in get_loc    raise KeyError(key) from errKeyError: 5請幫忙，謝謝你的時間:)
