Python’s Approach to Variable Declaration
Consider the following examples:
# Python print(x) # Raises NameError: name 'x' is not defined x = 5 print(x) # Outputs: 5
In Python, attempting to use a variable before assigning a value to it will result in a NameError, clearly indicating that the variable is not defined.
