Python用for循环实现九九乘法表
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)
