TypeError: 'bpy_prop_collection' object is not callable

I’m trying to make the “Monstercat style audio visualizer” as in this video: https://www.youtube.com/watch?v=JDaSk2mX7HU

Strangely enough, I’ve gotten this to work before on my old Windows 7 PC and Blender 2.71, but apparently this time when I run this code on Windows 10 and Blender 2.72:

import bpy


for i in range(0, 64):
    
    bpy.ops.mesh.primitive_plane_add(location = ((i + (i*0.5)), 0, 0))
    bpy.context.scene.cursor_location = bpy.context.active_object.location
    bpy.context.scene.cursor_location.y -= 1
    bpy.ops.object.origin_set(type='ORIGIN_CURSOR')
    
    bpy.context.active_object.scale.x = 0.5
    bpy.context.active_object.scale.y = 20
    bpy.ops.object.transform_apply(location=False, rotation=False, scale=True)
    
    bpy.ops.anim.keyframe_insert_menu(type='Scaling')
    bpy.context.active_object.animation_data.action.fcurves[0].lock = True
    bpy.context.active_object.animation_data.action.fcurves[2].lock = True
    
    bpy.context.area.type = 'GRAPH_EDITOR'
    
    l = i**2 + 20
    h = (i+1)**2 + 20
    
    print(str(i) + str(l) + str(h))
    
    bpy.ops.graph.sound_bake(filepath=r'D:\Google Drive\Music\Nightcore and Nightstep\Born (Vocal Mix) [Nightcore Mix].mp3', low = (l), high = (h))
    
    bpy.context.active_object.animation_data.action.fcurves(1).lock = True

I get this error:


Traceback (most recent call last):
File "D:\Google Drive\AnimationRender.blend\Text", line 27, in <module>
TypeError: 'bpy_prop_collection' is not callable
Error: Python script fail, look in the console for now...

How can I fix this so I can move on with my project?

replace the parantheses with square brackets:

bpy.context.active_object.animation_data.action.fcurves(1).lock = True

That’s interesting, I’ll look into it later, my PC is getting repaired

EDIT: Hmm, parenthesis too op. Thanks!
