Adding sum of value back to Dictionary

February 28, 2023

I have a dictionary, and I’m trying to add 100 to the values. I’m able to do so, but I can’t seem to figure out how to insert the new values to show up in the dictionary.

for value in artist_dict.values():
  value += 100
  
print(artist_dict)

I tried .append(value) and received an error message. Also, value = artist_dict.values(), artist_dict.update(value), artist_dict.values() = value, and artist_dict.updated(value +=100) all received an error message.

>Solution :

you can add a fixed value to every value in a dictionary by iterating over the dictionary and adding the fixed value to each value. Here’s an example:

my_dict = {'a': 10, 'b': 20, 'c': 30}

fixed_value = 5

for key in my_dict:
    my_dict[key] += fixed_value

print(my_dict)

In this example, my_dict contains the original dictionary with keys ‘a’, ‘b’, and ‘c’, and corresponding values 10, 20, and 30, respectively. The fixed_value variable is set to the value that you want to add to each value in the dictionary.

The for loop iterates over the keys in the dictionary, and the my_dict[key] += fixed_value statement adds the fixed value to the current value for that key. This statement is equivalent to my_dict[key] = my_dict[key] + fixed_value.

Finally, the updated dictionary is printed using the print() function.
