我正在使用 python 创建一个程序，将一组 DNA 序列转换为氨基酸（蛋白质）序列。然后我需要找到一个特定的子序列，并计算存在这个特定子序列的序列数。这是我到目前为止的代码：

#Open cDNA_sequences file and read in line by line
with open('cDNA_sequences.csv', 'r') as results:

    for line in results:

        columns = line.rstrip("\n").split(",") #remove end of line characters and split commas to produce a list
        ensemblID = columns[0] #ensemblID is first element in our list
        dna_seq = columns[1] #dna_seq is second element in our list
        genetic code = {


        "UUU":"F", "UUC":"F", "UUA":"L", "UUG":"L",
        "UCU":"S", "UCC":"s", "UCA":"S", "UCG":"S",
        "UAU":"Y", "UAC":"Y", "UAA":"STOP", "UAG":"STOP",
        "UGU":"C", "UGC":"C", "UGA":"STOP", "UGG":"W",
        "CUU":"L", "CUC":"L", …
