Question
Choose the Correct Answer(s)
What will be the output after the following statements?
def xyz():
a = 56
xyz()
print(a)
Options
NameError
a = 56
xyz
56
Solution
Break Down the Problem
- We need to analyze the code provided and determine what happens when it is executed.
- The function
xyzis defined, and within it, a local variableais assigned the value56. - After calling the function
xyz, there is an attempt to print the value ofa.
Relevant Concepts
- Understand the scope of variables in Python: variables defined inside a function are local to that function and cannot be accessed outside of it.
- Recognize that an attempt to access a variable that is not in the global scope will raise a
NameError.
Analysis and Detail
- The function
xyz()sets a local variablea = 56. - After calling
xyz(), the variableadefined insidexyzdoes not exist in the global scope. - The line
print(a)is outside of the function and thus attempts to access the global variablea, which has not been defined.
Verify and Summarize
Based on the understanding of variable scope in Python, the attempt to print a will result in a NameError since a is not available in the global scope.
Final Answer
NameError
