Python program to remove the key from a dictionary
Summary:
Problem Statement: Write a Python Program to remove the key from a dictionary.
Description: Dictionary is key-value pair data structures in Python. We can get the value of the dictionary through its key.
Here is the syntax of the Python dictionary.
some_dict = {'a': 1, 'b': 2}
Here a and b are keys with values 1 and 2 respectively.
This is how a dictionary in Python looks. The value of a dictionary can be extracted using a key like some_dict['a']
will print 1.
Python Program: Remove the key from a dictionary
Copy
my_dict = {'name': 'Digvijay', 'age': 24, 'languages':['Python', 'Java', 'Javascript']}
print("Original Dictionary ",my_dict)
key_to_del = 'languages'
if(key_to_del in my_dict):
del(my_dict['languages'])
print("After deletion Dictionary ",my_dict)
Output
Original Dictionary {'name': 'Digvijay', 'age': 24, 'languages': ['Python', 'Java', 'Javascript']} After deletion Dictionary {'name': 'Digvijay', 'age': 24}
The logic of the program is simple. We first declare a variable with a dictionary.
We print the original dictionary (before deletion). The next step is to check if the key exists in the dictionary, it is important to avoid error keyError
.
In the next step, we delete the key-value pair.
Finally, we print the dictionary and compare the results.
