Hello, I student of computational design so I still practicing Python in rhino so I have some questions about coding.

 ![image](https://global.discourse-cdn.com/mcneel/uploads/default/original/4X/3/9/5/3955f2320e0408c0d6db9f9d88f9dcda4efdd6bc.png)  
from picture If x == 10 I wanna to print sin interpcurve else not 10 print sin points. How to code this condition? thank you

Hi,

I’m not exactly sure what it is that you want to do, but the code on lines 16 to 20 - currently commented out - should do the trick. On line 18, get rid of the space between `print` and `(new_curve)`. `print` in Python 3 is a function, thus the parentheses.

You can’t compute and thus print the sine of an interpolated curve or list or points. `math.sin()` excepts a floating point or integer number, representing an angle in radians.

What exactly is x? Where does it come into play? Is it a number, a list of something?

Something like this?

```python
import rhinoscriptsyntax as rs 
import math

points = []
scale = 1.5

for i in range(100):
    pt = ([scale * math.sin(i), i, 0])
    points.append(pt)

x = 10
if x == 10:
    [rs.AddPoint(pt) for pt in points]
else:
    rs.AddInterpCurve(points)

```

It would probably be a good idea to make `x` a boolean (True/False), instead of 10, since you only seem to want to switch between two cases.

**Example:**

```python
import rhinoscriptsyntax as rs 
import math

points = []
scale = 1.5

for i in range(100):
    pt = ([scale * math.sin(i), i, 0])
    points.append(pt)

bake_curve = False
if not bake_curve:
    [rs.AddPoint(pt) for pt in points]
else:
    rs.AddInterpCurve(points)

```
