Python: Extract a list of values from a given list of dictionaries
Python dictionary: Exercise-52 with Solution
Write a Python program to extract a list of values from a given list of dictionaries.
Sample Solution:
Python Code:
def test(lst, marks):
result = [d[marks] for d in lst if marks in d]
return result
marks = [{'Math': 90, 'Science': 92},
{'Math': 89, 'Science': 94},
{'Math': 92, 'Science': 88}]
print("\nOriginal Dictionary:")
print(marks)
subj = "Science"
print("\nExtract a list of values from said list of dictionaries where subject =",subj)
print(test(marks, subj))
print("\nOriginal Dictionary:")
print(marks)
subj = "Math"
print("\nExtract a list of values from said list of dictionaries where subject =",subj)
print(test(marks, subj))
Sample Output:
Original Dictionary: [{'Math': 90, 'Science': 92}, {'Math': 89, 'Science': 94}, {'Math': 92, 'Science': 88}] Extract a list of values from said list of dictionaries where subject = Science [92, 94, 88] Original Dictionary: [{'Math': 90, 'Science': 92}, {'Math': 89, 'Science': 94}, {'Math': 92, 'Science': 88}] Extract a list of values from said list of dictionaries where subject = Math [90, 89, 92]
