Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
Parameterized queries allow the moving of user data out of a string to be interpreted. Additionally, Criteria API [8] and similar APIs move away from the concept of command strings to be created and interpreted. Enforcing language separation via a static type system. [9] Validating or "sanitizing" input, such as whitelisting known good values ...

The Philadelphia Eagles were down to their third-string quarterback. That didn't keep them from dominating the Dallas Cowboys and their second-string thrower in a 41-7 Philadelphia blowout.
The problem stems from the use of unchecked user input as the format string parameter in certain C functions that perform formatting, such as printf(). A malicious user may use the %s and %x format tokens, among others, to print data from the call stack or possibly other locations in memory.
