当n大于9时，格式上有些没对齐。谁能留言解决呢？

#/usr/bin/python
#coding=utf-8
def num(n):
    for i in range(1,n+1):
        for j in range(1,i+1):
            print j,"*",i,"=",i*j,'\t',
        print ''
if __name__ == "__main__":
    num(4)


运行结果：
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

对不齐问题已经解决

def num(n):
    for i in range(1,n+1):
        for j in range(1,i+1):
            if i > 9:
                print j,"*",i,"=",i*j,'\t',
            else:
                print j,"*",i,"=",i*j,'\t','\t',
        print ''
if __name__ == "__main__":
    num(11)

运行结果：
