import arcpy
arcpy.ListUsers("Database Connections/admin.sde")The following example demonstrates how to print a list of connected users along with their connection time.
import arcpy
users = arcpy.ListUsers("Database Connections/admin.sde")
for user in users:
print("Username: {0}, Connected at: {1}".format(
user.Name, user.ConnectionTime))The following example demonstrates how to generate a new list of only SDE IDs from the list returned by ListUsers.
import arcpy
# Set the admistrative workspace connection
arcpy.env.workspace = "Database Connections/tenone@sde.sde"
# Create a list of users
'''
NOTE: When the arcpy.env.workspace environment is set, a workspace
does not need to be provided to the function.
'''
users = arcpy.ListUsers()
# Create a list of SDE ID's.
# Use a list comprehension to get the ID values in a new list.
id_users = [user.ID for user in users]
print(id_users)
