crazy python

Question

a = 1

a == 0

print(a)

i am not getting any error @ second line. because a is already defined. actually what will happen at second line??

Answer 1

Every expression (everything that has a 'value') can just sit in your code.

You could write this and it wouldn't cause an error:

print('Hello')
1
5+6
'Nobody hears me'
True
...
7==5
print('Bye')

Python doesn't mind if you write values.

However, if you don't *do* anything with the values, nothing (visible) will happen.

It's like:

You: 42
Python: Okay, and what of it?
You: Well...
Python: As you wish. What next?

The object will just be created, then directly forgotten again.

Answer 2

Why would you get error ?
At second line you are comparing a's value to 0
Like a==0
So it's 1==0
it will therefore return false

Answer 3

Excellent.

Answer 4

I understood it's an comparison operator bit my question is I just used the statement blank
