Python SyntaxError: invalid syntax for a valid statement

I have created a MWE:

x = True
if x:
    print('111111')
y = 1

When running in python interactive mode, I get

>>> x = True
>>> if x:
...     print('111111')
... y = 1
  File "<stdin>", line 3
    y = 1
    ^
SyntaxError: invalid syntax
>>>

The code looks very correct. If I add them line by line, they will be fine but now when copying them all together.

What is wrong?

>Solution :

The interpreter is saying that the indentation of the second statement y=1 was unexpected.You should have entered a blank line to end the first statement (i.e., "if") , before you start writing the next statements(i.e y=1).

>>> x=True
>>> if x:
...     print('1111')
...
1111
>>> y=1
