To access the items in a sublist, simply append an additional index:索引也是根据嵌套来的>>> x[1] ['bb', ['ccc', 'ddd'], 'ee', 'ff'] >>> x[1][0] 'bb' >>> x[1][1] ['ccc', 'ddd'] >>> x[1][2] 'ee' >>> x[1][3] 'ff' >>> x[3] ['hh', 'ii'] >>...
An iterable which supports efficient element access using integer indices via the getitem() special method and defines a len() method that returns the length of the sequence. Some built-in sequence types are list, str, tuple, and bytes. Note that dict also supports getitem() and len(), bu...
access Python数据分析(中英对照)·Tuples 元组 python 元组是不可变的序列,通常用于存储异构数据。 Tuples are immutable sequences typically used to store heterogeneous data. 查看元组的最佳方式是将其作为一个由多个不同部分组成的单个对象。 The best way to view tuples is as a single object that consist...
导入time模块,通过time.timezone查看时区,28800是秒单位,除60是分钟,在除60的结果是小时,也就是说中国时区比UTC早8个小时。 1.1 time.time time.time()查看时间戳,以秒为单位,这个数字实际没什么大的意义,只不过是从1970年开始算起到当前经历了多少秒。从1970年开始算是因为这是Unix诞生的时间。
Tuple Items Tuple items are ordered, unchangeable, and allow duplicate values. Tuple items are indexed, the first item has index[0], the second item has index[1]etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not chan...
