Question
What will be the output after the following statements?def xyz(): a = 56 xyz() print(a)OptionsNameErrora = 56xyz56
Solution
The output will be a NameError.
Here's why:
-
The function
xyz()is defined, and within this function, a local variableais set to 56. -
The function
xyz()is called. This executes the function and sets the local variableato 56. However, this variableaonly exists within the scope of the functionxyz(). -
After the function call,
print(a)is executed. However,ais not defined in this scope (outside of the function), so Python will raise a NameError, indicating thatais not defined.
So, the correct option is NameError.
