#how to write a comment out

This will run.

print (3 + 2 < 5 - 7)

Hens 30.0
Roosters 97
Now I will count the eggs:
6.75
False

print ("We can transport", carpool_capacity, "people today.")
print ("We have", passengers, "to carpool today.")
print ("We need to put about", average_passengers_per_car, "in each car.")

There are 100 cars available.
There are only 30 drivers available.
There will be 70 empty cars today.
We can transport 120.0 people today.
We have 90 to carpool today.
We need to put about 3.0 in each car.

Let's talk about Soham Chowdhury.
He's 173 cms tall.
He's 84 kgs heavy.
He's got Brown eyes and Black hair.
His teeth are usually White depending on the tea.
If I add 28, 173, and 84 I get 285.

There are 2 types of people.
Those who are Introvert and those who are not.
I said: 'There are 2 types of people.'.
I also said: 'Those who are Introvert and those who are not.'.
Isn't that a fact?! False
This is the left side of...a brain with a right side.
