Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
The Multics shell includes a run command to run a command in an isolated environment. [1] The DEC TOPS-10 [2] and TOPS-20 [3] Command Processor included a RUN command for running executable programs. In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
Stackless Python, or Stackless, is a Python programming language interpreter, so named because it avoids depending on the C call stack for its own stack. In practice, Stackless Python uses the C stack, but the stack is cleared between function calls. [ 2 ]
When several threads are waiting on a single condition variable, the system may decide to wake all threads up when it's signaled. The system treats every signal( ) to wake one thread as a broadcast( ) to wake all of them, thus breaking any possibly expected 1:1 relationship between signals and wakeup. [ 1 ]
There are two main complications. First, there is a risk that a race condition, where the barber sleeps while a customer waits for the barber to get them for a haircut, arises because all of the actions—checking the waiting room, entering the shop, taking a waiting room chair—take a certain amount of time. Specifically, a customer may ...
Processes are also removed from the run queue when they ask to sleep, are waiting on a resource to become available, or have been terminated. In the Linux operating system (prior to kernel 2.6.23), each CPU in the system is given a run queue, which maintains both an active and expired array of processes.
Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely, a parameter is a type, and an argument is an instance.
The Python programming language, which contains many Monty Python references as feature names, has an internal-only module called "Argument Clinic" to pre-process Python files. [17] [18] The sketch is referenced in a line of dialogue in the TV show House, season 6, episode 10, "Wilson". The character Dr. Wilson says to Dr. House "I didn't come ...
