Hints:
1. Define the "flap()" function:
2. Access the global variable "speed" inside "flap()".
3. Change the value of speed to change the movement of bird:
B
Step 1: Create the "flap()" function.
B
Task: Call the "flap()" function when the spacebar key is pressed.

C
global a
global b
global sum
Q.2
A
B
global sum
C
global sum.
The sum that is created inside show() is local. So, the "print" function will not access it. We have to use the global sum to specify that sum is global so that print() can show the correct value.
a=30
b=60
sum=0
def show:
sum=a+b
print(sum)ADDITIONAL ACTIVITY-1
