Question
What will be the output of the following Python code?x = 50def func(): global x print('x is', x) x = 2 print('Changed global x to', x)func()print('Value of x is', x)x is 50Changed global x to 50Value of x is 50None of the mentionedx is 50Changed global x to 2Value of x is 50x is 50Changed global x to 2Value of x is 2
Solution
The output of the given Python code will be:
x is 50 Changed global x to 2 Value of x is 2
Here's the step by step explanation:
- The variable x is initially set to 50.
- The function func() is defined, which first prints the current global value of x, which is 50.
- Inside the function, the global keyword is used to indicate that x in the function scope is the same as the global x. Then, x is set to 2.
- The function then prints that the global x has been changed to 2.
- The function func() is called, so the two print statements inside the function are executed.
- Finally, the value of x is printed after the function call. Since x was changed to 2 inside the function and the change was made to the global x, the final print statement prints that the value of x is 2.
