Cast a value with a other values type

Question

Is it possible to cast a number behalf of a other number? I tried this one, but type returns a string.

n = 1.34
i = 10
type(i)(n)

Answer 1

As mentioned, your example works fine:

>>> from decimal import Decimal
>>> a = 5
>>> b = 5.0
>>> c = Decimal(5)
>>> type(a)
<class 'int'>
>>> type(b)
<class 'float'>
>>> type(c)
<class 'decimal.Decimal'>

Cast b (float) as a's type (int):

>>> type(a)(b)
5

Cast a (int) as b type (float):

>>> type(b)(a)
5.0

Cast a (int) as c type (Decimal):

>>> type(c)(a)
Decimal('5')

Note that Python's duck-typing often makes this kind of casting unnecessary, though I can imagine some scenarios where it would be useful.
