The “KeyError” occurs when you try to access a dictionary key that doesn’t exist in the dictionary. This error typically indicates that you are referencing a key that is not present in the dictionary.
Consider the following code snippet:
student = {‘name’: ‘John’, ‘age’: 20}
print(student[‘grade’])
In this example, the dictionary student contains the keys 'name' and 'age'. However, when you try to access student['grade'], which is not a valid key in the dictionary, the “KeyError” occurs.
SyntaxError: Invalid syntax
Situation: A SyntaxError is a common error encountered in Python code when the interpreter encounters a statement or expression that violates the language’s syntax rules. This error typically occurs due to mistakes in the code structure, such as missing or misplaced characters, incorrect indentation, or incorrect use of keywords.
Example:
if x == 5
print(“x is equal to 5”)
