查找仅在 Python 中特定位置处可变的字符串的所有排列

[英]Find all permutations of a string that is variable only at specific positions in Python

I have a DNA sequence which is variable only at specific locations and need to find all possible scenarios:我有一个仅在特定位置可变的 DNA 序列,需要找到所有可能的情况:

DNA_seq='ANGK' #N can be T or C  and K can be A or G
N=['T','C']
K=['A','G']

Results:结果:

['ATGA','ATGG','ACGA','ACGG']

Searching online, It seems permutations method from itertools can be used for this purpose but not sure how it can be implemented.在线搜索,似乎itertoolspermutations方法可以用于此目的,但不确定如何实现。 I would appreciate any help.我将不胜感激任何帮助。

Use itertools.product :使用itertools.product

from itertools import product
result = [f'A{n}G{k}' for n, k in product(N, K)]

Result:结果:

['ATGA', 'ATGG', 'ACGA', 'ACGG']
