Deleting suffix from feature class name using ArcPy?

Question

I have to edit the Name of the feature classes in my databank by deleting the Suffix part called "_AAA_VV". I am not pro in ArcPy but prepared something which does not work.

Can you help to find my mistake?

import arcpy, os
database = r'C:...\Data_test.gdb' 
try:
for dataset in datasets:
 arcpy.env.workspace = os.path.join(database,dataset)
 features = arcpy.ListFeatureClasses()
 for feature in features:
 # feature.replace('_AAA_VV,'')
 feature.split('_AAA_VV,1)[0]
except Exception as e:
print("Found an error - {0}".format(e))

Answer 1

This should work

import arcpy
database = r'C:...\Data_test.gdb'
arcpy.env.workspace = database
datalist = arcpy.ListDatasets("*", "Feature")
for data in datalist:
 try:
 features = arcpy.ListFeatureClasses("*", "ALL", data)
 for feature in features:
 split = feature.split('_AAA_VV')
 arcpy.Rename_management(feature, split[0])
 except IndexError:
 print('Error found in feature - {0}'.format(feature))
