can perform the following operations on the list: append (), insert (), pop (), and [].
Of course, list can be defined by nesting, as follows:
#define a nest listl=['Michael','Luffy','Nancy', ['Corey','Jason']]
Tuple must be assigned a value during initialization, as shown below:
#define a tuplet=('Michael','Luffy','Nancy')
Here we need to explain the Non-modification of tuple. Tuple cannot be modified only by pointing to its elements. For example, in the above example, tuple points to 'Michael

And the decision to storeFour keys per node is really arbitrary. While all nodes would store the same number ofElements (except along the fringe-sometimes there just aren ' t enough elements to fill upThe fringe of the B-tree), the actual node size can be tweaked to maximise performance.In practice, the number is typically even, and a

If an element points to the same tree node as its sibling elements, they can share the entire style context .

use "kill" to end the task.
For processes running in the background, you can use the kill command to terminate:
# Du-A/| sort-Rn>/tmp/du. Sorted
[1] 237
# Killed 237
Or run the following command:
# Du-A/| sort-Rn>/tmp/du. Sorted
[1] 237
# Kill % 1
(2) For zombie processes, kill-9 can be used to force termination and exit.
For example, if a program has completely died and kill cannot exit without signal strength, the best way is to add signal strength-9, followed by killing the parent process.
