用python打印九九乘法表，要求以金字塔形式打印

参考一下吧 

for i in range(1,10):

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

# x=i*j

# print(i,'*',j,'=',x,end=' ')

print('%s*%s=%s' %(i,j,i*j),end=' ') # end=' '表示不换行，只是加个空格

print() # 单纯换行

for i in range(1,10):

for j in range(i,10):

print('%s*%s=%2d' %(i,j,i*j),end=' ') # end=' '表示不换行，只是加个空格

print() # 单纯换行

for i in range(1,10):

for k in range(1,i):

print(' ',end=' ')

for j in range(i,10):

print('%s*%s=%2d' %(i,j,i*j),end=' ') # end=' '表示不换行，只是加个空格

print() # 单纯换行

for i in range(1,10):

for k in range(1,10-i):

print(' ',end=' ')

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

print('%s*%s=%2d' %(i,j,i*j),end=' ') # end=' '表示不换行，只是加个空格

print() # 单纯换行

# 打印金字塔：

for i in range(1,22):

if i%2==0:pass

else:

x='*'*i

print(x.center(22,' '))

max_level = 5

for now_level in range(1,max_level+1):

for i in range(max_level-now_level):

print(' ',end=' ')

for j in range(2*now_level-1):

print('*',end=' ')

print()

for i in range(1,10):
    print(' '*int((60-6*i)/2), end='')  # 在每行前面留空格
    for j in range(1,i+1):
        print('%s*%s=%2d'%(str(j), str(i), i*j), end=' ')  # 每个公式占6个字符（乘积统一占两个字符）
    print()

参考这个https://blog.csdn.net/superwfei/article/details/117635943?spm=1001.2014.3001.5502

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

输出：

1 * 1 = 1 
1 * 2 = 2 2 * 2 = 4 
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9 
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16 
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49 
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64 
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
