Welcome Viewers,
In the series of programming, we’ve seen different types of errors in Python and handling
them. Now, in this tutorial, we will see another type of error i.e. KeyError.
What is KeyError?
KeyError raised mainly with dictionary whenever the key we are trying to access is not found.
Example:
d = { 1:1, 2:2, 3:3}
print(d[4]) // as ‘4’ is not a key in d, this will give an ‘KeyError’.

As KeyError is an inbuilt error, so using ‘try – except’ this error can be handled.
