Using Dictionary Data Structure to increment all values without creating a new dictionary.

Increment values in a Dictionary without creating a new Dictionary

To increment values in a dictionary without creating a new dictionary, you can iterate through the dictionary and directly modify its values. Here are two different scenarios to achieve this depending on the requirement.

Scenario 1:
Increment all values with the same number.

If the dictionary has integer values and you want to increment all of them by a certain amount. Let's create a dictionary named Fruits consisting of different fruits and their price per piece - increment all values by 1.

Fruits={ 'Orange':0.60,'Apple':0.70,'Grapes':0.30}
for fruit, price in Fruits. items():
Fruits[fruit]= price+1
print(Fruits)

Scenario 2:
Increment values with different numbers.

If you have a dictionary and want to increment all values for a specific key, put conditions accordingly. Let's create a dictionary named Fruits consisting of different fruits and their price per piece - increment the values according to the fruit. The price of an orange is increased by 1, an apple is increased by 2, and grapes by 3.

Fruits={ 'Orange':0.60,'Apple':0.70,'Grapes':0.30}
for fruit, price in Fruits. items():
if fruit=='Orange':
Fruits[fruit]=price+1
elif fruit=='Apple':
Fruits[fruit]=price+2
else:
Fruits[fruit]=price+3
print(Fruits)
