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)
