for row in myresult: print(row) In this code, the param_value is passed as a tuple to the execute method, replacing the ? (or %s in MySQL's Python connector) in the SQL query. C. Benefits Parameterized queries help prevent SQL injection attacks. Suppose we have a user input field in...
Becausea tuple containing a single value must be followed by a trailing comma. (See the documentation for thetuple data type in Python.) Without the trailing comma,('test')becomes the string'test'. Strings are a particular type of Python sequence, a sequence ofcharacters. This is why the ...

In this way, we evaluate f using a finite number of measurement shots; in this setting, we are only allowed imprecise queries to the cost function due to statistical errors with the finite number of measurement shots. Based on the central limit theorem61, we may model each imprecise query ...
