如何用Python找出list中所有升序片段

Question

如shuzu=[1,2,4,5,6]输出1,2和4,5,6

Answer 1

shuzu = [1,2,4,5,6,5,12,11,12,13]
cnt = 0     # 记录升序元素个数
for i in range(len(shuzu) - 1):
    if shuzu[i] + 1 == shuzu[i+1]:
        cnt += 1
        print(shuzu[i],end=",")
    else:
        if cnt >= 1:
            print(shuzu[i])
        cnt = 0
    if i == len(shuzu)-2:   #末尾元素处理
        print(shuzu[len(shuzu)-1])
