追加时取出特定字符串

如何解决追加时取出特定字符串

我正在尝试将某些DNA序列翻译成蛋白质序列，但遇到了一些核酸不完整的DNA序列。到目前为止，我已经通过使用它们在每次出现时增加一个计数器来克服它们，但是在添加它们时，我想将这些序列从我的列表中删除。 .strip（）函数仅在出现特定字母时才将其取出，但是如果发现不完整的核酸，我希望从列表中删除整个字符串。 作为参考，我将大约100个这些序列（请参见下文）并全部翻译。综上所述，当仅找到一个不是ACTG的字母时，如何删除序列之一？

C

到目前为止，正如我之前提到的，我的代码只是通过计算计数器来绕过任何错误。

protein = ''
protein_list = []
mutation = False
completed_HAseq = []
for sequence in selected_HAseqs:
    for i in range(0,len(sequence)-2,3):
        codon = sequence[i:i+3]
        if codon not in FASTAdict:
            total_mutation_count += 1
        elif codon in FASTAdict:
            protein += FASTAdict[codon]
            completed_HAseq.append(sequence)
    protein_list.append(protein)
    protein = ''

除了检查RYMKSWHBVDN的每个字符串外，我什么都没想到，如果有，请删除它。如果没有，我将其附加到翻译序列的最终列表中

解决方法

您可以检查并替换子字符串
