Python | Least Value test in Dictionary
While working with dictionary, we might come to a problem in which we require to ensure that all the values are atleast K in dictionary. This kind of problem can occur while checking status of start or checking for a bug/action that could have occurred. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using all() + dictionary comprehension
The combination of above functions can be used to perform the following task. The all function checks for each key and dictionary comprehension checks for the atleast K value.
# Python3 code to demonstrate working of# Least Value test in Dictionary# Using all() + dictionary comprehension # Initialize dictionarytest_dict = {'gfg' : 8, 'is' : 10, 'best' : 11} # Printing original dictionary print("The original dictionary is : " + str(test_dict)) # Initialize K K = 8 # using all() + dictionary comprehension# Least Value test in Dictionaryres = all(x >= K for x in test_dict.values()) # printing result print("Does all keys have atleast K value ? : " + str(res)) |
Output :
The original dictionary is : {'gfg': 8, 'best': 11, 'is': 10}
Does all keys have atleast K value ? : True
Method #2 : Using loop
This problem can be solved using brute force strategy using loop and we compare each key with K and return True if all elements are atleast K.
# Python3 code to demonstrate working of# Least Value test in Dictionary# Using loop # Initialize dictionarytest_dict = {'gfg' : 8, 'is' : 10, 'best' : 11} # Printing original dictionary print("The original dictionary is : " + str(test_dict)) # Initialize K K = 8 # using loop# Least Value test in Dictionaryres = Truefor key in test_dict: if test_dict[key] < K: res = False # printing result print("Does all keys have atleast K value ? : " + str(res)) |
Output :
The original dictionary is : {'gfg': 8, 'best': 11, 'is': 10}
Does all keys have atleast K value ? : True
