python dsws tool DS_Response.py pandas performance warning

dsws gets a performance warning from pandas

…\python3.12\latest\Lib\site-packages\DatastreamDSWS\DS_Response.py:361: PerformanceWarning: DataFrame is highly fragmented. This is usually the result of calling frame.insert many times, which has poor performance. Consider joining all columns at once using pd.concat(axis=1) instead. To get a de-fragmented frame,
use newframe = frame.copy()

offending line :
df[colNames] = None

temp hack:

import warnings
# Suppress PerformanceWarningwarnings.simplefilter(action='ignore', category=pd.errors.PerformanceWarning)

Thank you for reaching out to us.

The DatastreamDSWS library has been rebranded to DatastreamPy.

The code needs to be modified, as follows.

import DatastreamPy as DSWS

ds = DSWS.DataClient(None, username = username, password = password)

Please try this new DatastreamPy library.
