Question

以下是我到目前为止：在提示用户输入两个序列时似乎有错误。

def matchSequences(sequence1, sequence2):

    numMatches = 0

    (input("Enter the RNA sequences")==(sequence1, sequence2)

    for i in range(0,len(sequence1))

        if sequence1[i] == A and i in sequence2[i] == U
            numMatches = numMatches+1
        if sequence1[i] == C and i in sequence2[i] == G
            numMatches = numMatches+1
        if sequence1[i] == G and i in sequence2[i] == C
            numMatches = numMatches+1
        if sequence1[i] == U and i in sequence2[i] == A
            numMatches = numMatches+1
        elif numMatches == numMatches+0:


            for i in range (sequence1, sequence2)
                if i in sequence1[i]:
                    numMatches == numMatches+1
                elif numMatches == numMatches+0:
                    return numMatches

matchSequences()

Answer 1

在我看来，你应该拥有这样的东西，而不是(input("Enter the RNA sequences")==(sequence1, sequence2)：

sequence1, sequence2 = input("Enter the RNA sequences, seperated by a comma: ").split(",")

在这种情况下，您不需要函数来获取参数，您可以def matchSequences()。

如果您想要使用参数，请删除包含输入的行，保留原始def matchSequences(sequence1, sequence2)，而不是仅仅执行此操作：

matchSequences()

这样做：

first_sequence = input("Enter the first sequence: ")
second_sequence = input("Enter the second sequence: ")
matchSequences(first_sequence, second_sequence)

或者这个：

matchSequences(*input("Enter the RNA sequences, seperated by a comma: ").split(","))

（有关*在此处所做的事情，请参阅this问题。此外，here是str.split的文档。）

Answer 2

您可以尝试以下方式：

sequences = tuple(seq for seq in raw_input().split("."))

格式化一对序列：

AAAA.CCCC
