如何在Python中将具有数字和字符的列表中的数字仅转换为int

Question

I am learning Python and while practicing, I have this type of input:

• 1 2 3 4 S
• 3 4 5 6 N
• 3 4 1 8 S

It will always be a set of numbers separeted by space and end with a letter (char). I am reading it with input() and making it a list like this

data = input()
myList = data.split()

What I want is to take the list and put only the numbers to a new list. I tried this, but it only works if the list only has int values:

myList = [int(i) for i in myList]

How can I only take the int values and put them in a new list.

NOTE: My data input always ends with a letter but it will be nice if I someone gives a solution where there are letters at any random index of the list. Thanks in advance

Answer 1

您只需要向理解添加过滤器。

msj = [int(i) for i in msg if i.isdigit()]

Answer 2

I would do it like this

new_list = []
for item in myList:
    if item.isdigit():
        new_list.append(int(item))

Answer 3

您可以利用以下事实：字母始终出现在字符串的末尾：

newList =  [int(n) for n in myList[:-1]]
