Python-如何将包含多个数字的字符串转换为int？

Question

How can I convert a string containing more than one number to an int in python, for example: "100, 200, 300" and "400, 500" . I know how I can convert a string containing a single number such as "100" or "56" to an int but not a string which contains 2 numbers.

Does anyone know how this could be done?

Thank you so much for your help.

Answer 1

Using map() for mapping list element to int

x = "100, 200, 300"
list(map(int, x.split(",")))

Output:

[100, 200, 300]

Answer 2

You can also use list comprehensions :

In [635]: x = "100, 200, 300"
In [638]: results = [int(i) for i in x.split(',')]

In [639]: results
Out[639]: [100, 200, 300]
