How to check if keys exists in dictionary python?
A dictionary is a set of unordered key, value pairs. In a dictionary, The keys must be unique, and they are stored in an unordered manner.
Here we’ll see how to check if the key exists in the dictionary.

Dict = {'John':78, 'zoya':96, 'vicky':65, 'Sonia':85}
key = input()
try:
Dict[key]
except KeyError:
print("Key doesn't exist!")
else:
print("Key present!")
e.g.,
Dict = {'John':78, 'zoya':96, 'vicky':65, 'Sonia':85}
key = input()
if key in Dict:
print("Found!")
else:
print("Not Found!")
