Day 2 of Python Learning 🐍

Last day, we learned terminal basics, conditional statements, how to use Boolean datatype in Python, and what dynamic type is. Today, we will see some more things that I learned in Python.

I learned was Control Flow Statements.

Control Flow Statement

Control Flow Statements are used to control the execution flow of a program type of three.

1.Condition Statements

2.Lopping Statements

3.Jump Statements

Today we are going to learn two statements.😁

One is Conditional Statements, and another one is Looping Statements.

Condition Statements

Condition statement means checking a condition and running the code based on that condition.

Condition Statement key words

• if


• else


• elif 🤔

In JavaScript, I used else if.

In Python, we use elif for the same purpose. ( else + if = elif 😜 )

a =10

b =20

c =21

if a>=b and a>=c:

    print(a)

elif b>=a and b>=c:

    print(b)

elif c>=a and c>=b:

    print (c)



OutPut:

   c

• First I created three variables and assigned values to them.


• Then I used an if-elif condition statement to check which value is greater.


• Used to (ex) a>=b and a>=c, b>=a and b>=c, c>=a and c>=b


• Finally the program prints the largest number.📈

Looping Conditions

A looping condition is used to repeat a block of code again and again until the condition becomes false. two Type of Looping Conditions is Here

For Loop Condition and While Loop Conditions. but I Today only Learn in While Loop Condition.

While Loop

It is used to run the code until the condition becomes false.

I was create a while loop conditions by 4 task. see the task easy to Understand in while loop condition..

Task no: 1) 5 4 3 2 1



count =5

while count>=1:

    print(count,end=" ")

    count-=1

Output :

5 4 3 2 1

------------------------------



Task no: 2) 10 8 6 4 2



loop=10

while loop>= 2:

    print(loop,end=" ")

    loop-=2

Output :

10 8 6 4 2



------------------------------



Task no3) 15 12 9 6 3



count1 =15

while count1>=3:

    print(count1,end=" ")

    count1-=3

Output :

15 12 9 6 3



------------------------------



Task no:4) 25 20 15 10 5



count2 =25

while count2>=5:

    print(count2,end=" ")

    count2-=5

Output :

25 20 15 10 5

EX :

Task no 1

Full program flow:

• Create a Variable and Initialization starting value. count = 5


• Used a while Loop condition and Check the Condition. while count>=1:


• print the Count. print( Count )


• value decrease. count-=1 meaning count=5 > > 5 - 1 = 4 > > count =4


• again condition check. count value = 4 again print and again decrement the count.


• When the condition becomes false the loop stops. [ex] count is 0 >=1.

And I use All print inside end=" "

what is this end=""🤔

• end="" is used to control what comes after the print output.


• Normally print moves to the next line.😒
  

OutPut:



5

4              

3

2

1

• But using end="" we can print output in the same line.😃
  

OutPut :



5 4 3 2 1       

• We can use space, star, dash, or other symbols inside end="".😯
  

end="*",end="_"

OutPut :



5*4*3*2*1



5_4_3_2_1

I will continue my Python journey tomorrow...👋
