# Python | Filter dictionary of tuples by condition

| |

Method # 1: Using ` items () ` + Dictionary Comprehension
These functionality together can solve this problem. We can access all the values ​​with ` items () ` and the condition can be imposed by understanding the dictionary.

` `

` # Python3 code for demonstrations # Filter tuple dictionary by condition # Using items () + dictionary   # initializing dictionary test_dict = { ’a’ : ( 6 , 3 ), ’b’ : ( 4 , 8 ), ’ c’ : ( 8 , 4 )}   # print the original dictionary print ( "The original dictionary is:" + str (test_dict))   # Filter tuple dictionary by condition # Using items () + dictionary res = {key: val for key, val in test_dict.items () if val [ 0 ]" = 6 and val [ 1 ] " = 4 }    # print result print ( "The filtered dictionary is:" +   str (res)) `

` ` Output:

` The original dictionary is : {’b’: (4, 8),’ a’: (6, 3), ’c’: (8, 4)} The filtered dictionary is: {’ a’: (6, 3), ’c ’: (8, 4)} `

Method # 2: Using ` lambda + filter () `
E This method works in the same way as above, except for using the ` filter ` function instead of dictionary comprehension for compact logic. Only works with Python2.

 ` # Python code to demonstrate how it works ` ` # Tuple dictionary filter by condition ` ` # Using lambda + filter () `   ` # initializing dictionary ` ` test_dict ` ` = ` ` {` ` ’a’ ` `: (` ` 6 ` `, ` ` 3 ` `), ` ` ’b’ ` `: (` ` 4 ` `, ` ` 8 ` `), ` ` ’c’ ` `: (` ` 8 , 4 )} ``   # print the original dictionary print ( "The original dictionary is:" + str (test_dict))   # Filter tuple dictionary by condition # Using lambda + filter () res = dict ( filter ( lambda (x, (y, z)): y" = 6 and   z " = 4 , test_dict.items ()))   # print result print ( "The filtered dictionary is:" +   str (res)) `

Output:

` The original dictionary is: {’b’: (4, 8), ’a’: (6, 3),’ c’: (8, 4)} The filtered dictionary is: {’a’: (6, 3),’ c’: (8, 4)} `
