enumerate()函数用于将一个可遍历的数据对象(如列表，元组，字符串)组合为一个索引序列，同时列出数据和数据索引(下标)，一般用于for循环当中

读取pymol，显示sequence 将24-26号氨基酸改为β折叠alter 24-26/, ss='S'rebuild类似的代码还有如下，将不同的序列部分改为helix，lo

今天想分享一个主题：人类基因组时代的泛基因组学。主要内容源自今年《Nature Reviews Genetics》上一篇题为《Pan-genomics in the human genome era》的文章。

Among all the factors of a positive integer N, there may exist several consecutive numbers. For example, 630 can be factored as 3×5×6×7, where 5, 6, and 7 are t...

Given an increasing sequence S of N integers, the median is the number at the middle position. For example, the median of S1 = { 11, 12, 13, 14 } is 12, and the...

The set [1,2,3,...,_n_] contains a total of n! unique permutations.

The count-and-say sequence is the sequence of integers with the first five terms as following:

Given an unsorted array of integers, find the length of the longest consecutive elements sequence.

enumerate() 函数用于将一个可遍历的数据对象(如列表、元组或字符串)组合为一个索引序列，同时列出数据和数据下标，一般用在 for 循环当中。
