GET THE KEY OF A MINIMUM VALUE¶

In [1]:
sample_dict = {'physics':82,'maths':65,'history':75}

minimum_value = min(sample_dict.values())
minimum_keys = [key for key in sample_dict if sample_dict[key]==minimum_value]
print(minimum_keys)

['maths']

TO CHECK IF VALUE 200 EXISTS IN THE GIVEN DICTIONARY¶

In [6]:
sample_dict = {'a':100, 'b':200, 'c':300}
In [11]:
value = 200

if value in sample_dict.values():
    print(f"Yes, Value: '{value}' exists in dictionary")
else:
    print(f"No, Value: '{value}' does not exists in dictionary")

Yes, Value: '200' exists in dictionary

MERGE TWO PYTHON DICT INTO ONE¶

In [4]:
dict1 = {'ten':10, 'twenty':20, 'thirty':30}
dict2 = {'thirty':30, 'forty':40, 'fifty':50}
In [5]:
dict1.update(dict2)
print('updated dictionary:')
print(dict1)

updated dictionary:
{'ten': 10, 'twenty': 20, 'thirty': 30, 'forty': 40, 'fifty': 50}
