下面通过一段代码给大家介绍python 使用for 循环实现九九乘法表,具体代码如下所示:
#for 循环实现99乘法表 for i in range (1,10): for j in range (1,i+1): print("{}*{} = {:<4}".format(i,j,i*j),end = " ") print("") print('第1种'+"-"*96) for i in range (9,0,-1): for j in range (1,i+1): print("{}*{} = {:<4}".format(i, j, i * j), end=" ") print("") print('第2种'+"-"*96) for i in range (1,10): for k in range (1,i): print(end = " ") for j in range (i,10): print("{}*{} = {:<4}".format(i,j,i*j),end = " ") print("") print('第3种'+"-"*96) for i in range (9,0,-1): for k in range (1,i): print(end = " ") for j in range (i,10): print("{}*{} = {:<4}".format(i,j,i*j),end = " ") print("") print('第4种'+"-"*96) for i in range (1,10): for j in range (1,10): print("%d*%d=%2d" % (i,j,i*j),end = " ") print("") print('第5种'+"-"*96) for i in range (1,10): for j in range (i,10): print("%d*%d=%2d" % (i,j,i*j),end = " ") print("") print('第6种'+"-"*96) for i in range (9,0,-1): for j in range (1,i+1): print("%d*%d=%2d" % (i,j,i*j),end = " ") print("") print('第7种'+"-"*96) for i in range (1,10): for k in range (1,i): print(end = " ") for j in range (i,10): print("%d*%d=%2d" % (i, j, i * j), end=" ") print("") print('第8种'+"-"*96) for i in range (1,10): for k in range (1,10-i): print(end = " ") for j in range (i,0,-1): print("%d*%d=%2d" % (i, j, i * j), end=" ") print("") print('第9种'+"-"*96)
