| 2 年前 3 >>> classmates = ['Michael', 'Bob', 'Tracy']
>>> classmates
['Michael', 'Bob', 'Tracy']
变量 classmates 就是一个 list。用 len() 函数可以获得 list 元素的个数：
>>> classmates[0]
'Michael'
>>> classmates[1]
'Bob'
>>> classmates[2]
'Tracy'
>>> classmates[3]
Traceback (most recent call last):
File "", line len(classmates) - 1。
如果要取最后一个元素，除了计算索引位置外，还可以用-1做索引，直
接获取最后一个元素:
>>> classmates[-1]
'Tracy'
以此类推，可以获取倒数第 2 个、倒数第 3 个：
>>> classmates[-2]
'Bob'
>>> classmates[-3] 0 码力 |

## PROFILING
- Many Profilers used in Game Development Tracy, Intel VTune, Microsoft PIX, Custom
• Need profiler with instrumentation
• Need to see whole process dependencies
Using VTune - best view for data building

## Adding New Zones
To add new zones, use the JL_TIMING macro. You can find [Image](/uploads/documents/b/d/a/a/bdaac89e23dda6abe285d4efb4330c27/p1652_1.jpg)
