Change text based on frame

Question

I want to give an explanation in text during an animation I made in blender. However, with my current script, I only see the second text displayed during the whole animation. How do I change my code such that for frame 40-60 the first text is shown, and for frame 75-83 the second text?

Thanks in advance!

import bpy
scene = bpy.context.scene
obj = scene.objects['Text']
def recalculate_text(scene):
    frame = scene.frame_current
for frame in range(40, 60):
    obj.data.body = 'First Text'

for frame in range(75, 83):
    obj.data.body =  'Second Text' 


bpy.app.handlers.frame_change_pre.append(recalculate_text)

Get the object data (font curve), ask for the frame and check whether it's in a specific range using python's range(). Code based on Updating text object in Blender 2.81 using python

import bpy
scene = bpy.context.scene
obj = scene.objects['Font Object']
font_curve = obj.data
def recalculate_text(scene):
if scene.frame_current in range(40, 60):
    font_curve.body = "First Text: " + str(scene.frame_current)

if scene.frame_current in range(75, 83):
    font_curve.body = "Second Text: " + str(scene.frame_current)

else:
    font_curve.body = "Current Frame: " + str(scene.frame_current)


def register():
    bpy.app.handlers.frame_change_post.append(recalculate_text)
def unregister():
    bpy.app.handlers.frame_change_post.remove(recalculate_text)
register()
