程序for+i+in+range(1,10,2):print(i)输出的结果是您好亲，range(stop) -> range object range(3) -> (0, 1, 2) range(start, stop[, step]) -> range object range(1, 6) -> (1, 2, 3, 4, 5) range(1, 6, 2) -> (1, 3, 5) 上面的是range的使用方法, 结合for...

In summary, you should not write Python code like this: Python for i in range(len(lst_1)): print(lst_1[i]) In this code, you are creating a range of integers from 0 to the length of lst_1 and then you are accessing each element in the list by its index. This can lead to...
