What will be the output of the following Python code?def ct(x, y, z): global a x = 5 y = 6 z = 7 a = 8 print(x,y,z,a)x,y,z,a = 15,16,17,18ct(1,3,9)Options15 16 17 185 6 7 81 5 9 81 5 9 18

The output of the Python code will be "5 6 7 8".

Here's the step by step explanation:

1. The function ct(x, y, z) is defined, which takes three arguments. Inside this function, the global keyword is used to declare a as a global variable.

2. The variables x, y, z, and a are assigned the values 5, 6, 7, and 8 respectively.

3. The print statement inside the function will print the values of x, y, z, and a which are 5, 6, 7, and 8 respectively.

4. Outside the function, the variables x, y, z, and a are assigned the values 15, 16, 17, and 18 respectively. However, these assignments do not affect the print statement inside the function because the function has its own local variables x, y, and z. The global variable a is changed inside the function, but this change is not reflected outside the function because the print statement is inside the function.

5. The function ct(1,3,9) is called. The arguments passed to the function do not affect the print statement because the function assigns its own values to x, y, z, and a.

So, the output of the code will be "5 6 7 8".
