• 用*号输出字母c的图案

#用*号输出字母c的图案

spaceNum = [30, 25, 18, 15, 12, 10, 8, 6, 5, 4, 3, 3]
space = ' '
star = '*'
for i in range(1, len(spaceNum)):
    print(spaceNum[i] * space, star)
spaceNum.reverse()
for i in range(1, len(spaceNum)):
    print(spaceNum[i] * space, star)

建立了一个list，遍历list，将list元素作为空格，最后反向遍历再输出

• 第七题是特么什么玩意？直接pass
• 输出九九乘法表

'''输出九九乘法表'''
for i in range(1,10):
    for j in range(1,i+1):
        print(i,'x',j,'=',i*j,'\t',end='')
    print()

这个是不太难理解哦，其实可以更优化一点儿。
