In this article, let's look at the built-in functions in the Python dictionary, which I'll
What are the CMP in PythonFor instructions, and
pythoncmp ()method to parse. Well, don't say much, let's get into the article.
Describe
The CMP () function of a Python dictionary is used to compare two dictionary elements.
Grammar
CMP () method syntax:
CMP (Dict1, DICT2)
Parameters
Dict1--A dictionary of comparisons.
Dict2--A dictionary of comparisons.
return value
If the elements of the two dictionary return the same 0, if the dictionary dict1 is greater than the dictionary Dict2 returns 1, if the dictionary dict1 is less than the dictionary dict2 returns-1.
Instance
The following example shows how the CMP () function is used:
#!/usr/bin/python#-*-Coding:utf-8-*-dict1 = {' Name ': ' Zara ', ' Age ': 7};d ict2 = {' Name ': ' Mahnaz ', ' age ': +};d ict3 = {' name ': ' Abid ', ' age ': +};d ict4 = {' name ': ' Zara ', ' Age ': 7};p rint "Return Value:%d"% cmp (Dict1, dict2) print "return Value:%d "% cmp (DICT2, dict3) print" Return Value:%d "% cmp (Dict1, DICT4)
The result of the above example output is:
Return Value: -1return value:1return value:0
