Python Exercise: Remove duplicates from Dictionary

Python dictionary: Exercise-17 with Solution

Write a Python program to remove duplicates from Dictionary.

Sample Solution:-

Python Code:

student_data = {'id1': 
   {'name': ['Sara'], 
    'class': ['V'], 
    'subject_integration': ['english, math, science']
   },
 'id2': 
  {'name': ['David'], 
    'class': ['V'], 
    'subject_integration': ['english, math, science']
   },
 'id3': 
    {'name': ['Sara'], 
    'class': ['V'], 
    'subject_integration': ['english, math, science']
   },
 'id4': 
   {'name': ['Surya'], 
    'class': ['V'], 
    'subject_integration': ['english, math, science']
   },
}

result = {}

for key,value in student_data.items():
    if value not in result.values():
        result[key] = value

print(result)

Sample Output: 

{'id2': {'subject_integration': ['english, math, science'], 'class': ['V'], 'name': ['David']}, 'id4': {'subje
ct_integration': ['english, math, science'], 'class': ['V'], 'name': ['Surya']}, 'id1': {'subject_integration'
: ['english, math, science'], 'class': ['V'], 'name': ['Sara']}}

Python: Use Get() to Retrieve a Value in a Dictionary

>>> number_dict = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> number_dict[5]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 5
>>> number_dict.get(5, 'five')
'five'
