Hello everybody, I just studying Python 3.8 and I have a string number, how can I convert it to int, float data type?

- "2"  ->  2(int)

- "5.234" -> 5.234 (float)

Please help me, how can I convert them?

    You can use float() and int() to help convert them. For example:

    >>> a = "2"
>>> b = "5.234"
>>> int(a)
2
>>> float(b)
5.234
>>> int(float(b))
545
>>> int(b)
545

    Hope it helpful for you!

    You can create a common function help convert string to int or float as below:

    def num(a):
    try:
        return int(a)
    except ValueError:
        return float(a)

    I still use it in my project. And it work fine for me.
