Enable python.analysis.completeFunctionParens
For what I expected for this feature See Examples below: (| as cursor)

Ex1

a = |"123456"

type int then accept suggestion:

a = int(|"123456")   # also it can expand selection in parentheses

Ex2

a = |"123456" and "789"

type int then accept suggestion:

a = int(|"123456" and "789")   # also it can expand selection in parentheses

Ex3

a = |("123456" and "789")

type int then accept suggestion:

a = int(|"123456" and "789")   # also it can expand selection in parentheses
