Posted on 25th July 2024| views
A Python KeyError exception is something that raised while you decide to obtain a key that is not present within a dictionary ( dict ). Python official documentation states that the KeyError is raised while a mapping key is obtained and is not located within the mapping. The most popular mapping in Python is the dictionary.
Fix key error
program:
values = {"x" : 1, "y" : 2, "z" : 3}
# Utilisng the value directly can cause an error.
try:
print(values["w"])
except KeyError:
print("encountered the key error")
# We apply to get to reliably get a value.
print(values.get("w"))
Output
Encountered the key error
