⏭️⏭️Python add to Dictionary. There is no explicitly defined method to add a new key to the dictionary. If you want to add a new key to the dictionary, then you can use assignment operator with dictionary key. Note that if the key already exists, then the value will be overwritten.⏮️⏮️

⏭️⏭️d={'A':1,'B':2,'C':3} key=raw_input("Enter key to check:") if key in d. keys(): print("Key is present and value of the key is:") print(d[key]) else: print("Key isn't present!")⏮️⏮️
