for m in range (1,5: for n in range(1,5: print m," ",n print " " 写程序,输出以下内容
N=5 for m in range(1,5: for n in range(1,m+1: print m,"",n print " "
2.写程序,输出以下内容
讨巧的办法就是把第1-2中的m和n互换 N=5 for m in range(1,N: for n in range(1,m+1: print n,"",m print " " 3.写程序,输出以下内容
# encoding: utf-8
def gen(line_cnt: ''' @param: line_cnt 行数''' for row in range(1,line_cnt+1: for col in range(1,row+1: print '%d %d\t' % (col,row, print ''
if __name__ == '__main__': gen(4
4.写程序,输出以下内容
# -*- coding: cp936 -*- #enconding: utf-8 def gen(line_cnt: ''': @param:行数 ''' for i in range(1,line_cnt+1: for j in range(1,i+1: m=i*j print '%s*%s=%s\t' % (i,j,m,#这边的逗号很重要，有了逗号，才能不换行print''
