Python：如何在列表中打印类型

Python: How to print types within a list

提问by RPmich

So I was given a list and I must print the type of each item in the list. I can clearly see that there are strings and integers but I need it to print out in Python. We just learned for loopsso I feel like that is what they are looking for but I cannot get it to print out.

所以我得到了一个列表，我必须打印列表中每个项目的类型。我可以清楚地看到有字符串和整数，但我需要它在 Python 中打印出来。我们刚刚学习了for 循环，所以我觉得这就是他们正在寻找的东西，但我无法将其打印出来。

Here is how I would do it using type().

这是我将如何使用type().

myList = [1,1.0,"moo"]  #init the array
for i in myList: 
    print(type(i)) #loop and print the type

use the typebuilt in function of python.

使用typepython的内置函数。

lst = ['string', 1, 2, 'another string']
for element in lst:
   print type(element)

output:

输出：

<type 'str'>
<type 'int'>
<type 'int'>
<type 'str'>

Essentially, the typefunction takes an object and returns the type of it. Try the below code:

本质上，该type函数接受一个对象并返回它的类型。试试下面的代码：

for item in [1,2,3, 'string', None]:
    print type(item)

Output:

输出：

<type 'int'>
<type 'int'>
<type 'int'>
<type 'str'>
<type 'NoneType'>

foo = [1, 0.2, "bar"]
for i in foo:
    print(type(i))

Should print out the type of each item

应该打印出每个项目的类型

ls = [type(item) for item in list_of_items]
print(ls)
