' AND " difference?

Question

pythn eg.
>>> print('Hello world!')
Hello world!

Me 1
>>> print( " Hello world! " )
Hello world!

Me 2
>>> print(' "Hello world! " ')
"Hello world!"

Me 3
>>> print( ' Hello world! ")
SyntaxError: EOL while scanning string literal

If ' and " are the same, why "Me 3" results Error?

I don't want to tell my self that they look different or it is the rule...

Answer 1

They aren't same. If you start from " then, you have to close it with this only.
See the following example:-
print(" ' ' ") # prints ' '
print(' " " ') # prints " "
If you will not close it with the same, it will give you an exception(EOL error)

"EOL while scanning string literal" means thar the interpreter did not find the ending quote
