StartCreateListForLoopAddToNewListEnd 以上流程图展示了整个操作的过程:从创建包含数字的列表开始,然后通过for循环遍历每个数字,最后将每个数字的平方添加到新列表中。 状态图 为了更好地理解操作过程中的状态变化,我们可以使用状态图来表示: Create a new listBegin for loopAdd item to list

Here, we are going to learn how to create a list from the specified start to end index of another (given) list in Python. By IncludeHelp Last updated : June 22, 2023 Given a Python list, start and end index, we have to create a list from the specified index of the list...
Have a look at the Python syntax below. It shows a for loop that consists of two lines. The first line specifies that we want to iterate over a range from 1 to 4. The second line specifies what we want to do in this loop, i.e. in each iteration we want to add a new column ...
