在python中执行语句时出现语法错误

Question

>>> x=5
>>> y=10
>>> if(x>y):
... print 'x is greater':
  File "<stdin>", line 2
    print 'x is greater':
        ^
IndentationError: expected an indented block

Answer 1

错误消息说明了一切。 Python使用缩进来处理块，并且因为print语句应该在if块内，所以它应该缩进：

>>> x=5
>>> y=10
>>> if(x>y):
...     print 'x is greater': # Note the indentation here
