FOR LOOP

For loopን በ Python የምንጠቀመው የሆነን line of code ወይም እንደ list, tuple, string, range, numbers... የመሳሰሉ sequence of elements በተደጋጋሚ execute ለማረግ ነው። ይህ ደግሞ በsequenceኡ እያንዳንዱ item ላይ ተመሳሳይ operation እንድናካሄድ ይረዳናል።

በPython የfor loop basic syntax ይሄን ይመስላል:

for item in sequence:
    # do something with item

በsyntaxኡ ውስጥ:

- "item" የሚለው በእያንዳንዱ Iteration(ድግግሞሽ) የsequenceኡን every item ይወክላል(placeholder variable ነው።)

- "sequence" የሚለው ደግሞ የሚወክለው loopኡ iterate የሚያረግባቸው elements of sequenceን ነው።

እስኪ ከላይ ያለውን ሀሳብ በምሳሌ እንየው፣ በምሳሌው ደግሞ የሆነ የቁጥሮች ስብስብ አለ ፣ ከዛም በlistኡ iterate እያረገ እያንዳንዱን ቁጥር print የሚያደርግ program ለመፃፍ እንሞክራለን።

We will learn deeply about lists in the future...

numbers = [1, 2, 3, 4, 5]

for num in numbers:
    print(num)

This would output:

1
2
3
4
5

For loopን ከrange() functionም ጋር መጠቀም እንችላለን፣ በዚህ ደግሞ የሆኑ range of numbers ላይ iterate እናረጋለን።

የ range() function Python built-in function ሲሆን sequence of numbers እንድንፈጥር ይረዳናል። እናም ከfor loop ጋር ተጠቅመን over the sequence of numbers iterate ማድረግ እንችላለን።

የ range() function syntax ይሄን ይመስላል፡

range(start, stop, step)

- start is the starting number of the sequence (optional, default is 0)

- stop is the ending number of the sequence (required)

- step is the difference between each number in the sequence (optional, default is 1)

ምሳሌ 1: በrange function ከ0-9 ቁጥሮችን ለማውጣት ከፈለግን፡ range(9) ማለት እንችላለን።

ምሳሌ 2:


for kutir in range(1, 6):
    print(kutir)

This would output:

1
2
3
4
5

Perceptive:

Two twin boys were raised by an alcoholic father. One grew up to be an alcoholic and when asked what happened, he said “I watched my father."

The other grew up and never drank in his life. When asked what happened, he said “I watched my father."

Two boys, same dad, two different perspectives.

Your perspective in life will determine your destination.

FOR LOOP

❓What will be the output of the above code?

Comment your answer!

@python_pioneers

Description for the above code

The above Python code will print the string "hello world" ten times. Here's a breakdown of how it works:

1. The for loop is set to iterate over the range from 1 to 10 inclusive. The range(1, 11) function generates a sequence of numbers starting from 1 up to (but not including) 11.

2. On each iteration of the loop, the print('hello world') statement is executed.

Because the loop iterates 10 times, "hello world" will be printed 10 times, each on a new line.

Here is the code:

for i in range(1, 11):
    print('hello world')

Output

hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world

Everyone Has a Story in Life

A 24 year old boy seeing out from the train’s window shouted…

“Dad, look the trees are going behind!”

Dad smiled and a young couple sitting nearby, looked at the 24 year old’s childish behavior with pity, suddenly he again exclaimed…

“Dad, look the clouds are running with us!”

The couple couldn’t resist and said to the old man…

“Why don’t you take your son to a good doctor?” The old man smiled and said…“I did and we are just coming from the hospital, my son was blind from birth, he just got his eyes today.”

Every single person on the planet has a story. Don’t judge people before you truly know them. The truth might surprise you.

FLOW CONTROL : WHILE LOOP

ዛሬ ማታ ከባለፈው ትምህርት የቀጠለ በPython ስለ While loop እንማራለን።

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.
