问题描述
如何在python循环中获取项目以建立列表.在php中,我将使用以下内容:
How do I get items in a python loop to build a list. In php I would use something like this:
$ar1 = array("Bobs","Sams","Jacks");
foreach ($ar1 as $ar2){
$ar3[] = "$ar2 array item"; }
print_r($ar3);
产生
Array ( [0] => Bobs array item [1] => Sams array item [2] => Jacks array item )
$ar3[]
将项目存储在数组中的foreach中.
$ar3[]
stores the item in the foreach in an array.
在Python中,我尝试过:
In Python i tried:
list1 = ("Bobs","Sams","Jacks");
foreach list2 in list1:
list3 = list2 + " list item"
print list3
产生
Jacks list item
但是它不会返回list3
作为列表,并且list3[]
无法正常工作.如何让循环进入列表?
But it doesn't return list3
as a list and list3[]
doesn't work. how do I get the loop to feed into the list?
推荐答案
这应该使您入门:
list1 = ['Me','You','Sam']
list2 = ['Joe','Jen']
for item in list2:
list1.append(item)
list1现在是['Me', 'You','Sam','Joe','Jen']
如果要第三个列表,只需定义它,然后附加到它.
If you want a third list, simply define it and append to it instead.
