Python Question

For example:

`def some_function(a):`

if a == 1:

return x ** 2

else:

return x - 1000

some_function(a)(b)

And as result when we have

`a==1`

`b**2`

`b-1000`

Is it even possible in python, to get as return some unknown variable, which will be replaced by another?

The question is exactly about not touching

`b`

And the code which should work is

`some_function(a)(b)`

The other answer is correct in this case, but may not be suitable for what you are trying to do.

What you are trying to do is *return a function*, which Python makes extremely easy:

```
def some_function(a):
if a == 1:
def f(x):
return x ** 2
else:
def f(x):
return x - 1000
return f
>>> some_function(1)(5)
25
>>> some_function(0)(1500)
500
```
