To create it, let's run this code:
import pandas as pd
df = pd.read_clipboard(index_col="Index")
I want to concatenate the lists and get a pandas.Series. Here is how I do it:
print(df.sum(axis=1))
I get what I want but I have the following warning:
C:\Program Files\JetBrains\PyCharm Community Edition 2022.1.3\plugins\python-ce\helpers\pydev\_pydevd_bundle\pydevd_utils.py:605: FutureWarning: The behavior of `series[i:j]` with an integer-dtype index is deprecated. In a future version, this will be treated as *label-based* indexing, consistent with e.g. `series[i]` lookups. To retain the old behavior, use `series.iloc[i:j]`. To get the future behavior, use `series.loc[i:j]`.
s = s[:max_items]
C:\Program Files\JetBrains\PyCharm Community Edition 2022.1.3\plugins\python-ce\helpers\pydev\_pydevd_bundle\pydevd_utils.py:606: FutureWarning: iteritems is deprecated and will be removed in a future version. Use .items instead.
for item in s.iteritems():
I'm using PyCharm 2022.2.3 (Community Edition).
I'm using Python 3.10.2.
I'm using the latest version of the library pandas pandas==1.5.0.
The pydevd_utils included in your PyCharm version aren't compatible with the to-be-changed behavior described in the warning.
You can ignore the warnings for now.
The bug is being tracked here on JetBrains' YouTrack system.
