invalid keyword argument for int()

I have tried without the type, with float - what is my newby mistake here?

def calcAge(age):
    return int(birth=20 - age)

age = int(input("What age will you turn this year? "))
birth = int(calcAge(age))

RESULT:

What age will you turn this year? 54

Traceback (most recent call last):
File "D:/DSDJ/My files/ParameterPassReturnTest.py", line 13, in <module>
  birth = int(calcAge(age))
File "D:/DSDJ/My files/ParameterPassReturnTest.py", line 8, in calcAge
  return int(birth=20 - age)
TypeError: 'birth' is an invalid keyword argument for int()

Process finished with exit code 1

The int call is a function. By saying "birth=20-age" you are basically saying, "The argument birth is (20-age)". The function is looking for that argument but cannot find it and that is why you get that error. Just do 

def calcAge(age):
    return 20 - int(age)

age = int(input("What age will you turn this year? "))
birth = calcAge(age)

The problem is on this line:

return int(birth=20 - age)

int() is a method that takes an argument. You're giving it a named argument birth, but that's not what it expects. Remove the name, to this, gets you closer:

return int(20 - age)

Unfortunately age is not an int. I think what you want is this:

return 20 - int(age)

You can then remove the int() call a few lines later.
