Control Flow Modifiers in Python

በpython Control flow modifiers የምንላቸው በloop ወይም በconditional statements ውስጥ ከገቡ normal flow of executionን የሚቀይሩ statementኦች ናቸው።
እነዚህም modifiers እነ break, continue, እና pass ናቸው

1. break Statement
ይህን የ break statement የምንጠቀመው አንድን loop prematurely ወይም መጨረሻ ላይ ሳይደርስ ለማቆም ስንፈልግ ነው። እናም loopኡ terminate ያረግና ከloopኡ ቀጥሎ መጀመሪያ ያለው line of code executed ይሆናል።


- ለምሳሌ:

  for i in range(10):
      if i == 4:
          break
      print(i)  # Output: 0, 1, 2, 3
  

2. continue Statement

ይህኛው modifier ደግሞ የloopኡ current iteration ውስጥ ያለውን code ዘለን ወደ ቀጣይ iteration ለማለፍ ስንፈልግ እንጠቀመዋለን።
loopኡን terminate አያረገውም ፣ it just skips the remaining code for the current iteration.


- ለምሳሌ:

  for i in range(10):
      if i % 2 == 0:
          continue
      print(i)  # Output: 1, 3, 5, 7, 9
  

..to be contd

#break
#continue

3. pass Statement

It is a no-operation statement in Python
- pass statementን የምንጠቀመው እንደ place holder ነው። ማለትም የሆነ code እየፃፋችሁ ከሆነ ግዜ በኃላ የምትጨምሩት line of code ካለ 'pass' ን እንደ place holder ትጠቀሙታላችሁ።

- ለምሳሌ:

  if condition:
      pass  # To be implemented later
  

4. else Clause with Loops

else clause ከloop ጋር መጠቀም እንችላለን፣ as long as a break statement is not used.

- ለምሳሌ:

  for i in range(5):
      print(i)
  else:
      print("Loop completed")  # This will be printed because the loop was not terminated by a break
  

- ምሳሌ : elseን after break ስንጠቀም:

  for i in range(5):
      if i == 3:
          break
      print(i)
  else:
      print("Loop completed")  # This will not be printed because the loop was terminated by a break
  

እነዚህን control flow modifiers መረዳት የloops እና conditionals flow manage በማረግ efficient እና readable code መፃፍ እንድትችሉ ይረዳችኋል።

#pass
#break

2. What will be the output of the following code?

   for i in range(5):
       if i == 3:
           break
       print(i)
   

- A) 0 1 2

- B) 0 1 2 3

- C) 0 1 2 3 4

- D) None of the above

4. What will be the output of the following code?

   x = 5
   while x > 0:
       x -= 1
       if x == 2:
           continue
       print(x)
   

- A) 4 3 2 1 0

- B) 4 3 1 0

- C) 5 4 3 2 1

- D) 5 4 3 1 0

You're gonna write a python program that processes numbers from 1 to 20 and follow these rules.

1. Skip (continue) numbers that are divisible by 3.

2. Stop (break) the loop if the number is greater than 15.

Print all the other numbers

You can use for loop to iterate through the numbers 1 to 20
