但是在循环体中不能怎么做,列表循环一般有两种方式,一种是for i in range(len(lst)),另外一种是for item in lst。 第一种循环 AI检测代码解析 num_list = [1, 2, 3, 4, 5] print(num_list) for i in range(len(num_list)): if num_list[i] == 2: ...
c=list(zip(a,b))foriinrange(len(c)):print("本次的长度是:",len(c))print("本次的i是:",i) c.pop(i)#原因就在于其i一直增大,而本身i的范围一直减小 本次的长度是: 3本次的i是: 0 本次的长度是:2本次的i是:1本次的长度是:1本次的i是:2Traceback (most recent call last): ...
