所以我有一個DNA序列 DNA = "TANNNT" where N = ["A", "G", "C", "T"] 我希望有TAAAAT, TAAAGT, TAAACT, TAAATT.....等所有可能的輸出。 現在從網上我發現了排列的解決方案,我可以做 perms = [''.join(p) for p in permutations(N, 3)] 然後就重複我的DNA序列 TA + perm
from datetime import datetime, timedelta
d = datetime.now()
data = [d + timedelta(minutes=i) for i in range(100)]
# prepare and group the data
from itertools import groupby
def get_key(d):
我有,我想每一個循環的末尾增加一倍龜元素的列表,但它沒有返回 level = 1
number_of_enemies = 5
enemies = []
for i in range(number_of_enemies):`
enemies.append(turtle.Turtle())
while True:
for level < 4
[for ene
list_a = []
for color in [True,False]:
for piece in range(1,7):
list_a = list_a + function(piece,color)
這裏function(piece,color)返回一個列表,我想加入,最後返回長長的名單,可以itertools.chain在這裏使用?因爲我認爲它可能會更快。我只
