Dictionary Operations

[admin]

Dictionary:


A dictionary in Python is a data structure that stores the value in value:key pairs. The most common associated method of dictionaries are get(), keys(), values(), items(), update(), pop(), clear() etc.
Example: Dict = {1: ‘ICAI', 2: 'For', 3: ‘CA’}
As you can see from the example, data is stored in key: value pairs in dictionaries, which makes it easier to find values.

#Client Ledger (Name -> Balance)
ledger = {"Ramesh": 12000, "Suresh": -5000}
print("Ramesh's balance:", ledger["Ramesh"])

#Update balance

Code: Select all

ledger["Suresh"] += 2000
print("Updated Suresh's balance:", ledger["Suresh"])

#Looping through ledger

for client, balance in ledger.items():
