用for循环写出的九九乘法表（包括函数的调用）

#方向一

for i in range(1,10):
    for j in range(1,i+1):
        d = i * j
        print('%d*%d=%-2d'%(i,j,d),end = ' ' )
    print()

下图为上面代码运行结果：

以下为函数练习，函数和for循环结合的九九乘法表（没有上面的简洁明了）
#方向一

def hanshu(n):
    m = n
    sums = 0
    for j in range(1,n+1):
        sums = m*j
        print("%d*%d=%-2d"%(m,j,sums),end = " ")
    print("")
def hanshu1():
    for i in range(1,10):
        hanshu(i)
hanshu1()

下图为上面代码运行结果：

#方向二

def hanshu(n):
    m = n
    sums = 0
    for j in range(1,n+1):
        sums = m*j
        print("%d*%d=%-2d"%(m,j,sums),end = " ")
    print("")
def hanshu1():
    for i in range(9,0,-1):
        hanshu(i)
hanshu1()

下图为上面代码运行结果：

#方向三

def hanshu(n):

m = n

sums = 0

for k in range(0,10-n):

print(" ",end = "")

for j in range(1,n+1):

sums = m*j

print("%d*%d=%-2d"%(m,j,sums),end = " ")

print("")

def hanshu1():

for i in range(1,10):

hanshu(i)

hanshu1()

下图为上面代码运行结果：

#方向四

def hanshu(n):
    for dix in range(10-n,0,-1):
        print("       ",end = "")
    sums = 0
    m = n
    for j in range(1,n+1):
        sums = m*j
        print("%d*%d=%-2d"%(m,j,sums),end = " ")
    print("")
def hanshu1():
    for i in range(9,0,-1):
        hanshu(i)
hanshu1()
