1.左下角输出

 for i in range(1,10):
    for j in range(1,i+1):
        print("%s*%s=%s"%(i,j,i*j),end=" ")
    print()

2.左上角输出

for i in range(1,10):
    for j in range(i,10):
        print("%s*%s=%s"%(i,j,i*j),end=" ")
    print()

3.右上角

for i in range(1,10):
    for k in range(1,i):
        print(end="       ")
    for j in range(i,10):
        print("%d*%d=%d"%(i,j,i*j),end=" ")
    print("")

4.右下角

for i in range(1,10):
    for k in range(1,10-i):
        print(end=" "*7)
    for j in range(1,i+1):
        print("%d*%d=%d"%(i,j,i*j),end=" ")
    print()
