I'm not sure why I'm getting a TypeError (float object cannot be interpreted as integer) in this code:

Following the Think Python textbook (second edition).

Trying to get past this one section but repeatedly running into an error that seems very confusing to me, as I've simply copied the code from the book.

import turtle
def polygon(t, length, n):
    for i in range(n):
    t.fd(length)
    t.lt(360/n)
import math
def circle(t, r):
    circumference = 2 * math.pi * r
    n = int(circumference/3) + 3
    length = circumference/n
    polygon(t, n, length)

bob=turtle.Turtle()
circle(bob, 100)

When I do this I end getting an error code:

Traceback (most recent call last):

.... circle(bob, 100)

... polygon(t, n, length)

... for i in range(n):

... TypeError: 'float' object cannot be interpreted as an integer

I've seen other similar questions on stackoverflow about this section but I haven't seen anyone with a Type Error before. I think this section of the book must be written in a kind of confusing way since people seem to be making a lot of errors here, and I've definitely struggled with trying to follow what code goes with what code and what code explicitly does not.

This is the book, by the way

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
