python一行sql太长折成多行并且有多个参数的方法

A=1
B=2
C=3

sql = "update student t set t.name = '',t.sex = '',t.age = '',t.height = '',t.weight = '',t.class = '',t.stuid = '',t.xxx = '' where t.stuid= '' and t.xxx = '';"

A=1
B=2
C=3
sql = ("update student t set t.name = '%s',"
     "t.sex = '%s',"
     "t.age = '%s',"
     "t.height = '%s',"
     "t.weight = '%s',"
     "t.class = '%s',"
     "t.stuid = '%s',"
     "t.xxx = '%s'"
     " where t.stuid= '%s'"
     " and t.xxx = 'P';" %(A,B,A,B,B,A,A,B,C)
  )
