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 ...
考虑将一个矩阵（列表的列表）中所有元素乘以2：matrix =[[1,2,3],[4,5,6],[7,8,9]]doubled_matrix =[[2* elem for elem in row]for row in matrix]print(doubled_matrix)# 输出：[[2, 4, 6], [8, 10, 12], [14, 16, 18]]使用条件表达式过滤元素列表推导式中，if condition部分可以对...
