如何从输入中选取三个连续的字母并附加到lis

Question

askGene=input("Enter Gene:")

ans=askGene.upper()

print(ans)

newStr=''

start=0

end=0

newList=[]

for i in askGene:

    new=ans[start:end]

    newList.append(new)

    start+=3

    end+=3

print(newList)

Answer 1

使用列表理解：

askGene = "ABCDEFGHIJKLMNOPQR"
newList = [askGene[i:i+3] for i in range(0, len(askGene), 3)]

这将产生以下输出：

['ABC', 'DEF', 'GHI', 'JKL', 'MNO', 'PQR']
