Common Use Cases

1. Waiting for User Input: የፈለግነውን data እስከምናገኝ User input በተደጋጋሚ እንድንቀበል ይረዳናል።


2. Processing Data Streams: መጨረሻ ላይ እስከምንደርስ data ከfile ወይም ከ network stream continuously እንድናነብ ይረዳናል።

3. Polling: የአንድን resource status periodically check እንድናረግ ይረዳናል።

ምሳሌ: User Input

Here's an example where we keep asking the user for a positive number:

number = -1
while number < 0:
    number = int(input("Enter a positive number: "))
print("You entered: ", number)

ከላይ ያለው ፕሮግራም userኡ positive ቁጥር እንዲያስገባ repeatedly ይጠይቀዋል፣ ቁጥሩን ደግሞ print ያረጋል፣ if the user enters a positive number the loop ends, because the condition becomes false.

👋 Let me share with you some beautiful and powerful quotes that I gathered from different sources.👇

People were created to be loved. Things were created to be used. The reason why the world is in chaos, is because things are being loved and people are being used.

- John Green

You get a strange feeling when you're about to leave a place. Like you'll not only miss the people you love but you'll miss the person you are now at this time and this place, because you'll never be this way ever again.

- Azar Nafisi

People ask if you have graduated, if you have married, if you have kids, as if life is like a checklist. No one asks you if you're happy

- Criolo

If you get tired, learn to rest, not to quit.

- Banksy

The sun does not forget a village just because it is small.

- African Proverb

A bird sitting on a tree is never afraid of the branch breaking, because its trust is not on the branch but on its own wings. Always believe in yourself

- Anonymous

Raise your words, not your voice. It is rain that grows flowers, not thunder.

- Rumi

If you think you are too small to make a difference, try to sleep with a mosquito in a room.

- Dalai Lama

You can't keep blaming yourself. Just blame yourself once and move on.

- Homer Simpson

Have a nice day!

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

@python_pioneers
@python_pioneers

...contd

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
