Code:
Python 3.5.2 (default, Nov 23 2017, 16:37:01)

>>> for i in range(3):
... print(1)
... print(2)
File "<stdin>", line 3
print(2)
^
SyntaxError: invalid syntax
Expected output:
1
1
1
2
With several test, I knew python interactive shell return invalid syntax error when the indentation block has lower.
Test code:
if true:
print("test")
print(test)
output:
File "<stdin>", line 3
print("test")
^
SyntaxError: invalid syntax
To solve this problem, I must using Enter key.
>>> for i in range(3):
... print(1)
...
1
1
1
>>> print(2)
2
But why? why I have to separate two code using enter? I want to know the reason.
Note: I'm bad at English and it's hard to describe it. "end of indentation" and "indentation block has lower" means that situation
if true: //no indentation, no tab or space
print(1) //in if syntax, we have to make indentation
print(2) //when if end, We don't make indentation. Compare to line 2, 'indentation block has lower' and 'indentation had ended'
I don't think it's right expression, So you may a little confused. if you understand this, please edit this question and make it right.
