Q:2. Assume that the "min" function computes the minimum of two values, and "max" function computes the maximum of two values. Let x1, x2 be 2 distinct integers. What can you say about the following program (using python 3.X version):
y1 = min(x1, x2)
y2 = max(y1, x1)


1.If x1 is smaller than x2, then y1 and y2 will be same.

2.If x1 is greater than x2, than y1 wll be equal to x2.

3.If we further run y3 = max(y1,y2) , then y3 will always be equal to x1.

4.All of the above

When X1 <X2,then Y2 and Y1 will be same. And when X1>X2 then X2=Y1.If We will run y3 then it is always be equal to x1.So all of the above is correct answer.

Q:3. Which of the below statement/s is/are true for global keyword in python ?

1.It is used to read global variables inside a function.

3.A variable name inside a function can be same as variable name of a global variable.

4.All of the above

In python , Global keyword is used to read global variables inside a function and if we want to use value of global variable inside a function, then use global keyword. And a variable name inside a function ,it can be same as global variable. So here All of the above is correct option.

Q:4. What will be the output of the following code:-
def keywordExample(x=1, y=2, z=4):

keywordExample(y=8,x=4,z=y)


1.Error
