What are some common variable errors I might encounter in Python?
Common variable errors in Python include NameError, TypeError, and UnboundLocalError. Would you like examples of each?
Yes, please provide examples of those errors.
Sure! A NameError occurs when you try to use a variable that hasn't been defined. For example, print(x)
when x
is not defined.
What about TypeError?
A TypeError happens when an operation is applied to an object of inappropriate type. For instance, trying to add a string and an integer: result = 'Hello' + 5
.
And UnboundLocalError?
An UnboundLocalError occurs when a local variable is referenced before it has been assigned a value. For example, if you try to print a variable inside a function that hasn't been initialized.
