Python – Remove dictionary from a list of dictionaries if a particular value is not present
When it is required to remove dictionary from a list of dictionaries if a particular value is not present, a simple iteration and the ‘del’ operator is used.
Example
Below is a demonstration of the same −
my_list = [{"id" : 1, "data" : "Python"},
{"id" : 2, "data" : "Code"},
{"id" : 3, "data" : "Learn"}]
print("The list is :")
print(my_list)
for index in range(len(my_list)):
if my_list[index]['id'] == 2:
del my_list[index]
break
print("The result is :")
print(my_list)Output
The list is :
[{'id': 1, 'data': 'Python'}, {'id': 2, 'data': 'Code'}, {'id': 3, 'data': 'Learn'}]
The result is :
[{'id': 1, 'data': 'Python'}, {'id': 3, 'data': 'Learn'}]Explanation
A list of dictionary elements is defined and is displayed on the console.
The list of dictionary is iterated over, and the ‘value’ associated with every key is checked to equivalent to 2.
If yes, that specific element is deleted.
The control breaks out of the loop.
In the end, this list of dictionary is displayed as output on the console.
