[英]Key error 5 issue when using Jupyter notebook commands into pycharm
I stumbled over a issue in which I do not understand or can not find a solution in solving.我偶然发现了一个我不理解或找不到解决方案的问题。
The codes I type functions perfectly in my Jupyter Notebook but caused an error when I used PyCharm.我键入的代码在我的 Jupyter Notebook 中运行完美,但在我使用 PyCharm 时出现错误。
I typed in these codes in PyCharm:我在 PyCharm 中输入了这些代码:
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']
Using these codes alone and printing their values are a success.单独使用这些代码并打印它们的值是成功的。 H
H
However when matched with these lines of code:但是,当与这些代码行匹配时:
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])
it returns this error:它返回此错误:

The above exception was the direct cause of the following exception:
Traceback (most recent call last):

and not df_ticker.Close[i-1] >= df_ticker [i-2]:

raise KeyError(key) from err

Please help, Thank you for your time:)请帮忙,谢谢你的时间:)
and not df_ticker.Close[i-1] >= df_ticker [i-2]:
and和
KeyError: 5
df_ticker.Close[ 5 ] or df_ticker [ 5 ] doesn't exist. df_ticker.Close[ 5 ] 或 df_ticker [ 5 ] 不存在。
it was supposed to be:它应该是:
df_ticker.Close[i] > df_ticker.Close[i-2]
I missed the second Close.我错过了第二次关闭。
