Our first if statement checks to determine if the variable i is between 1 and 9; if it is, we will add five to it and continue. The continue operator says: “Stop here, and go to the next iteration of our loop.” Experiment with this script to see how adding other conditions can ...
Python 使用的是左闭右开区间,意思是切片区间包含 start,但不包含 stop。如果省略了start 或者 stop,则切片会分别包含从头开始或者从末尾开始的所有元素。step 决定了切片的方向和步长。如果令步长为 2,那么切片就会从左到右每两个元素取一个值;如果令步长为 -3,则切片会从右到左每 3 个元素取一个值。默认步...
