解决python多行注释引发缩进错误的问题

如下所示：m_start=date+'09:00'm_end=date+'13:00'rsv_1={'act':'set_resv','dev_id':dev_id,'start':m_start,'end':m_end

如下所示：

 m_start =date +' 09:00'
 m_end =date +' 13:00'

 rsv_1 ={
 'act':'set_resv',
 'dev_id':dev_id,
 'start':m_start,
 'end':m_end,
 }

'''
 rsv_2 ={
 '_':'',
 'act':'set_resv',
 'dev_id':dev_id,
 'start':'2018-05-21 13:00',
 'end_time':'',
 'kind_id':'',
 'lab_id':'',
 'memo':'',
 'prop':'',
 'room_id':'',
 'end':'2018-05-21 17:00',
 'start_time':'',
 'term':'',
 'test_id':'',
 'test_name':'',
 'type_name':'',
 'type':'dev',
 'up_file':'',
 }
 rsv_3 ={
 '_':'','act':'set_resv',
 'dev_id':dev_id,
 'start':'2018-05-21 17:00',
 'end_time':'',
 'kind_id':'',
 'lab_id':'',
 'memo':'',
 'prop':'',
 'room_id':'',
 'end':'2018-05-21 21:00',
 'start_time':'',
 'term':'',
 'test_id':'',
 'test_name':'',
 'type_name':'',
 'type':'dev',
 'up_file':'',
 }
''' 
 session =requests.Session()
 req = session.post(init_url,data=keywords,headers=headers)

注意，这里的多行注释会报缩进错误，原因是因为python用缩进标志程序块，包括注释，所以，注释同样要注意与所要注释的程序块对齐．

改进如下，请注意下面代码中多行缩进的缩进情况：

 m_start =date +' 09:00'
 m_end =date +' 13:00'

 rsv_1 ={
 'act':'set_resv',
 'dev_id':dev_id,
 'start':m_start,
 'end':m_end,
 }

 '''
 rsv_2 ={
 '_':'',
 'act':'set_resv',
 'dev_id':dev_id,
 'start':'2018-05-21 13:00',
 'end_time':'',
 'kind_id':'',
 'lab_id':'',
 'memo':'',
 'prop':'',
 'room_id':'',
 'end':'2018-05-21 17:00',
 'start_time':'',
 'term':'',
 'test_id':'',
 'test_name':'',
 'type_name':'',
 'type':'dev',
 'up_file':'',
 }
 rsv_3 ={
 '_':'','act':'set_resv',
 'dev_id':dev_id,
 'start':'2018-05-21 17:00',
 'end_time':'',
 'kind_id':'',
 'lab_id':'',
 'memo':'',
 'prop':'',
 'room_id':'',
 'end':'2018-05-21 21:00',
 'start_time':'',

 }
