第3题 5个数字一行输出
每当你做一道题目时,记住要明确你的目的是什么
你的代码执行出来会是一个什么效果
然后根据你想要的这个效果去编辑代码
题目:输出1~100(不包含100)之间的偶数,5个数字一行输出
<?php for($i=1;$i<100;$i++){ if($i%2==0){ echo $i,"\t"; if($i%5==0){ echo "<br>"; } } } ?>
试试看python的写法吧
for i in range(1,100): if i%2==0 : print(i,end='\t') if i%5==0 : print()发现python输出的结果能对齐,但是php的不能
