Reusability

• How to make set of instructions written to be reused.

Find all the multiples of 3 below 100

• Operator Set: + – * / % == <= >= < >
• Solution 1

index = 1
muliple = 3
max = 100

until mulitple * index <= 100
  print mulitple * index
  index = index + 1
end

• Solution in python

def multiples(multiple, max):
    index = 1
    while multiple * index <= max:
        print(multiple*index)
        index = index + 1

        
print("multiples of 3 till 100 are ")
multiples(3, 100)
print("multiples of 5 till 200 are ")
multiples(5, 200)
     

• Debugging Hint:

  • Step Over : Execute the current statement and move to the next statement
  • Step Into : Get inside the function and execute from there
  • Breakpoint: Statement where the execution is stopped for manual debugging.

• Each Python file is called as module.

• Functions in one python module can be used in other python modules by importing modules.
