继上一个问题here之后，我面临另一个挑战。
我有以下新的listA
listA = ['rs141130360\tchr1:16495\tC\t653635\tNC_024540.1\tTranscript\tintron_variant,non_coding_transcript_variant\t-\t-\t-\t-\t-\trs3210724\tG\tMODIFIER\t-\t-1\t-\tSNV\tWASH7P\tEntrezGene\tHGNC:38034\ttranscribed_pseudogene\t-\t-\t-\t-\t-\t-\t-\t-\t-\tRefSeq\tG\tG\tOK\t-\t-\t-\t-\t8/10\t-\t-\tNR_024540.1:n.1080+112C>G\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\t-\n',

和相同的listB和空白的listC
ListB = ["NC", "NG", "NM", "NP", "NR", "XM", "XP", "XR", "WP"]
listC = []
使用以下代码，我可以通过将listA中的字符串匹配到listB的第五列来根据listB对listA重新排序：
d = {x: i for i, x in enumerate(listB)}
def get_index(s):
by_tabs = s.split('\t')
by_underscore = by_tabs[4].split('_')
return d[by_underscore[0]]
listC = sorted(listA, key=get_index)
和listC将输出：
print(listC)

我想返回listC中每个listB根据key排序的dictionary中的第一个元素。我尝试快速获得所需的输出如下：我有一个附加的词典，其中包含来自第一TSV列（dictionary = { 'rs141130360': 'value', 'rs62636367': 'value', etc...}
for i in list(dictionary.keys()):
print(next((x for x in listC if i in x), ""))
将正确打印：

但是，问题是我的真实listA包含532493个元素。遍历这个庞大的列表需要花费很多时间。
我希望在上面获得相同的输出，但需要的运行时间更少（30 mins之后，它正在运行，但仍未完成。如果我猜对了，应该对函数{{ 1}}，但目前还不确定该怎么办。
