What is a While Loop?

የተወሰነ ሁኔታ እውነት እስከሆነ ድረስ በፓይዘን ውስጥ ለተወሰነ ጊዜ loop በተደጋጋሚ የኮድ እገዳን ይፈጽማል። ጥቅም ላይ የሚውለው የድግግሞሽ ብዛት አስቀድሞ በማይታወቅበት ጊዜ እና አንዳንድ ሁኔታዎች በሚሟሉበት ጊዜ ነው.

While loop በPython አንድን block of code specify የተደረገው condition እውነት እስከሆነ ድረስ repeatedly(በተደጋጋሚ) execute የሚያረግ የ Python flow control አይነት ነው። While loopን የምንጠቀመው number of iteration ለማይታወቅባቸው ወይም executionአቸው on some condition ላይ depend ለሚሆንባቸው blocks of code ነው።

Syntax of While Loop

የ While loop basic syntax ይሄንን ይመስላል:

while condition:
    # Code block to be executed

- condition: አንድ condition እውነት ወይም ሀሰት እንደሆነ evaluate የሚያረግ expression ነው።

- Code block: ይሄ ደግሞ specified የሆነው condition True በሆነ ቁጥር execute የሚደረግ የstatements ስብስብ ነው።

Flowchart of a While Loop

1. Evaluate the condition.
2. If the condition is true, execute the code block.
3. Re-evaluate the condition.
4. If the condition is still true, repeat the code block.
5. Continue until the condition becomes false.

...cont'd

ምሳሌ:
በዚህ ምሳሌ የምናየው program ከ 1 እስከ 5 ያሉ ቁጥሮችን print የሚያረግ ነው:

i = 1
while i <= 5:
    print(i)
    i += 1  # Increment the value of i by 1

Detailed Explanation

1. Initialization: i is initialized to 1 ማለትም i የሚባል variable initial valueውን አንድ አርገናል።

2. Condition Check: i <= 5 check ይደረጋል: conditionኡ እውነት ከሆነ loopኡ ይቀጥላል otherwise loopኡ terminate ያረጋል።

3. Body of Loop: print(i) የ variable 'i' ን current value print ያረጋል።

4. Increment: i is incremented by 1 using i += 1.
Increment ማለት የአንድን variable value በሆነ ያህል አማውንት መጨመር ማለት ነው፣ በላይኛው case each time the variable 'i' is being incremented by 1.

5. Re-evaluation: The condition i <= 5 is checked again with the new value of i.

Infinite Loop

While loopን ስንጠቀም common የሆነ ችግር ቢኖር የinfinite loop መፈጠር ነው። ይህም infinite loop conditionኡ False መቼም በማይሆንበት ጊዜ ይፈጠራል።


Example of an infinite loop:

while True:
    print("This will print forever")

ከላይ ያለው ፕሮግራም "This will print forever" የሚለውን ዐ/ነገር ያለ ገደብ print ያረጋል።


Breaking Out of a Loop

Infinite Loop avoid ለማረግ "break" statement መጠቀም እንችላለን፣ ይህም የሆነ condition set አርገን እውነት በሚሆንበት ጊዜ loopኡን exit እንድናረግ ይረዳናል።

i = 1
while i <= 10:
    print(i)
    if i == 5:
        break  # Exit the loop when i is 5
    i += 1

ከላይ ያለው ፕሮግራም መጀመሪያ የተፃፈው ከ 1 እስከ 10 ያሉ ቁጥሮችን print እንዲያረግ ቢሆንም የ'i' value 5 ሲሆን እንዲያቆም ቅድመ-ሁኔታ ስላስቀመጥን ልክ የ'i' value 5 ሲሆን loopኡ ይቆማል።


Using Else with While Loop

Python 'else' clause ከ while loop ጋር እንድንጠቀም ይፈቅዳል። የ'else' block executed የሚሆነው የ while loop condition ሀሰት ሲሆን ነው። (i.e., the loop terminates naturally).

ምሳሌ

i = 1
while i <= 5:
    print(i)
    i += 1
else:
    print("Loop has ended")

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!
