Append string in the middle of a query in python -

-

i'm trying build query in python, i'm looking elegant way append condition in middle of string:

def get_raw_queryset(frequency=none, where_condition=none):     qs = "select id, count(*) count user_transaction_log " \          # want append if not none          if where_condition:              "where .... = 1" \          "group type , strftime('{0}', datetime) order id" \          .format(frequency)     return qs

this work long can safely evaluate string if where_condition not string:

"select ..." + bool(where_condition) * ("where ...") + "group ..."

i hope you're being extremely careful avoid sql injection.
