ExampleGet your own Python Server Get the value of the "model" key: thisdict = { "brand": "Ford", "model": "Mustang", "year": 1964 }x = thisdict["model"] Try it Yourself » There is also a method called get() that will give you the same result:...
有了打开的recordset我们就可以遍历字段: >>> flds_dict = {} >>> for x in range(rs.Fields.Count): ... flds_dict[x] = rs.Fields.Item(x).Name 字段的类型和大小可以这样得到: >>> print rs.Fields.Item(1).Type 202 # 202 is a text field >>> print rs.Fields.Item(1).DefinedSize 50...
要实现字段的批量赋值,可以使用Python中的字典(dict)来存储这些字段的键值对,并通过循环遍历字典进行赋值。具体的方法如下: 创建一个字典,将要赋值的字段和对应的值以键值对的形式存储在字典中。 使用循环遍历字典的键值对,并通过键访问到字段,然后将对应的值赋给字段。 以下是一个示例代码: # 定义一个类 class M...
