not not id(object())//3%2

btw, I'm aware this isn't at all random, my initial version of this was an instance of malicious compliance with the tests. In fact, you can make this method perform hilariously badly:

In [1]: d = {True: 0, False: 0}

In [2]: for _ in range(1000000): d[not not id(object())//3%2] += 1

In [3]: d
Out[3]: {True: 0, False: 1000000}

In [4]: for _ in range(1000000): d[not not id(object())//3%2] += 1

In [5]: d
Out[5]: {True: 0, False: 2000000}

In [6]: for _ in range(1000000): d[not not id(object())//3%2] += 1

In [7]: d
Out[7]: {True: 1000000, False: 2000000}

Function id() always returns the even number. Your function is not random and always return True.

You can't do this... Function id() always returns the even number. Your function is not random and always return True.

what is this ?

no,no and no again. Don't use string concatenation, this is bad for performances.

without module

Can you approve my decision?

It was hard, I spent 2 days and 2 nights, but I made it. It's awesome!
Good for everyone

thanks for the tip

Yeap, It's the best I've seen.

There have to be random tests for this solution to be impossible

The original instrunctions were:

Write a method that determines if there is a "Tyrannosaurus" within the array.

dammit, you got me!

That's awesome!

Dam, best one so far in length.
