[mai mult...]How to Fix an Operation Did Not Complete Virus Error on Windows by Adding the File to the Antivirus Exclusion List
If you trust your file and its source, and you think your antivirus has mistakenly recognized it as a potential threat you can add it to your antivirus’ whitelist so your future access to the file isn’t blocked. This way, you can keep your antivirus enabled while still keeping your access to the file open.
[mai mult...]KeyError: ‘key_name’
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.
IndexError: list index out of range
The “IndexError” occurs when you try to access an index of a sequence (such as a list or a string) that is outside the valid range of indices. This error typically indicates that you are trying to access an element at an index that doesn’t exist in the sequence.
Let’s consider the following code snippet:
numbers = [1, 2, 3]
print(numbers[3])
print(numbers[3])
In this example, the list numbers contains three elements, indexed as 0, 1, and 2. However, when you try to access numbers[3], which is outside the valid range, the “IndexError” occurs.
