1. Get the key of a minimum value from the following dictionary.

   Given Input: sample_dict = {'Physics': 82,'Math': 65,'history': 75}

   Expected output: Math

sample_dict = {'Physics':82,'Math':65,'History':75}

min_value = min(sample_dict.values())

for k,value in sample_dict.items():
    if value == min_value:
        print(k)

Math

1. Write a Python program to check if value 200 exists in the following dictionary.

   Given Input: sample_dict = {'a': 100, 'b': 200, 'c': 300}

   Expected output: 200 present in a dict

sample_dict = {'a':100,'b':200,'c':300}

if 200 in sample_dict.values():
    print("200 present in a dict")
else:
    print("200 is not present in the dict")

200 present in a dict

1. Merge two Python dictionaries into one

   Given Input: dict1 = {'Ten': 10, 'Twenty': 20, 'Thirty': 30} dict2 = {'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

   Expected output: {'Ten': 10, 'Twenty': 20, 'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

dict1 = {'Ten': 10, 'Twenty': 20, 'Thirty': 30}
dict2 = {'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

dict3 = dict1.copy()
dict3.update(dict2)

print(dict3)

{'Ten': 10, 'Twenty': 20, 'Thirty': 30, 'Fourty': 40, 'Fifty': 50}
