How to convert string into number in python

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

There is a list of numeric characters:

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

Want to convert each element into 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 it is 3.x, Map returns a map object, which of course can also be converted to List:

numbers = list(map(int, numbers))

3. There is another more complicated point:

for i, v in enumerate(numbers): numbers[i] = int(v)
