Analysis of the method of converting list elements into numbers in Python

The example in this article describes how the list elements in Python are converted to numbers. Share to everyone for your reference, as follows:

There is a list of numeric characters:

numbers = [' 1 ', ' 5 ', ' 10 ', ' 8 ']

You want to convert each element to a number:

numbers = [1, 5, 10, 8]

Use a loop to solve:

New_numbers = [];for N in Numbers:  new_numbers.append (int (n)); numbers = New_numbers;

Is there a simpler statement that can be done?

1.

numbers = [Int (x) for x in numbers]

2. python2.x, you can use the map function

Numbers = map (int, numbers)

If 3.x,map returns a Map object, it can also be converted to a list:

Numbers = list (map (int, numbers))

3. There is also a more complex point:

For I, V in Enumerate (numbers): numbers[i] = Int (v)
