Question

When Python is first installed, the default setting executes users’ code input line-by-line. But sometimes I need to write programs that execute multiple lines at once. Is there a setting in Python where I can change the code execution to one block at once?

>>> if (n/2) * 2 == n:;
        print 'Even';
        else: print 'Odd'

Error:

SyntaxError: invalid syntax

When I tried to run the above code, I got an invalid syntax error on the else.

Your indentation is wrong. Try this:

>>> if (n/2) * 2 == n:
...     print 'Even'
... else: print 'Odd'

Also you might want to write it on four lines:

>>> if (n/2) * 2 == n:
...     print 'Even'
... else:
...     print 'Odd'

Or even just one line:

>>> print 'Even' if (n/2) * 2 == n else 'Odd'
