標籤：print   turn   列表   append   很多   continue   +=   end   多種實現   

#coding=utf-8list=[]for i in range(1,101):    list.append(i)# print(list)tempList=[]newList=[]while True:    num=0    for temp in list:        tempList.append(temp)        num+=1        if num==3:            newList.append(tempList)            tempList=[]            num=0            continue    if temp==100:        newList.append(tempList)        breakprint(newList)

輸出：

[[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12], [13, 14, 15], [16, 17, 18], [19, 20, 21], [22, 23, 24],.......[100]]

 

oldList=[x for x in range(1,101)]newList=[oldList[x:x+3] for x in range(0,len(oldList),3)]print(newList)

輸出：

[[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12], [13, 14, 15], [16, 17, 18], [19, 20, 21], [22, 23, 24],.......[100]]

 

def f(x,y,z):    return x,y,zm = list(map(f, [x for x in range(1,101,3)], [y for y in range(2,101,3)], [z for z in range(3,101,3)]))print(list(m))

輸出：

[(1, 2, 3), (4, 5, 6), (7, 8, 9), (10, 11, 12), (13, 14, 15), (16, 17, 18), (19, 20, 21), (22, 23, 24),......(100)]

類似方法還有很多，需要多多研究
