Compare dictionary sizes with CMP in Python

1. Dictionary length

   The dictionary dic1,dic2 values, and the comparison results are as follows:

   650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/5A/65/wKiom1T8WleC2rRYAAB-yg7JBdg034.jpg "title=" QQ picture 20150308221727.png "alt=" Wkiom1t8wlec2rryaab-yg7jbdg034.jpg "/>

   The longer the dictionary length, the larger the dictionary.

   Question one: If the length is different, the length is longer but the key value is smaller, that big?

   650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M00/5A/65/wKiom1T8W5uRddAwAACIGsqRC7M028.jpg "title=" QQ picture 20150308222301.png "alt=" Wkiom1t8w5urddawaacigsqrc7m028.jpg "/>

   Answer: Dictionary length is the first comparison, long length of the big

2. Equal length, compare keys

Question two: If the key is not the same and relatively small, but the Valuse value is big?

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M01/5A/61/wKioL1T8YEKytfxSAABzAjglxnk639.jpg "style=" float: none; "title=" QQ picture 20150308223621.png "alt=" wkiol1t8yekytfxsaabzajglxnk639.jpg "/> 650" this.width=650; "src=" http ://s3.51cto.com/wyfs02/m01/5a/65/wkiom1t8xyjqy_ahaab2jot1tzc792.jpg "title=" qq picture 20150308223652.png "alt=" Wkiom1t8xyjqy_ahaab2jot1tzc792.jpg "style=" float:none; "/>

If the key value is not the same, the dictionary with large key value is large.

3. Equal length and equal key values, then compare dictionary values

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/5A/61/wKioL1T8Xb3Qg_E0AACOCUXBjoM165.jpg "title=" QQ picture 20150308222720.png "alt=" Wkiol1t8xb3qg_e0aacocuxbjom165.jpg "/>

In the case of equal lengths: Compare the first valuse,valuse value to the large one, and the second valuse for equality.

Question three: If the value is a string, the strings have equal, but one of them is longer

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M00/5A/65/wKiom1T8ZaqQCfmFAACbObREd4w594.jpg "title=" QQ picture 20150308230539.png "alt=" wkiom1t8zaqqcfmfaacbobred4w594.jpg "/> Answer: When comparing strings, each letter is compared, you can have the result, if the string is less than the end, But one of the strings is longer, and the string is large.
