#PRINTING  SOMETHING:- (SENTENCES OR WORDS)

   CODE-     

AFTER   WRITING    print - {AS PYTHON IS CASE SENSITIVE SO WE HAVE TO WRITE PRINT  AS- print NOT IN CAPITAL LETTERS }    AND   PUTTING   BRACKETS  ()  IN   THIS   BRACKETS WHATEVER   WE   HAVE    TO   WRITE   AS    A   OUTPUT    IF    IT'S    A   STRING   WE WILL   WRITE   IT   IN   QUOTES    I.E  (" ") ( ' ') .  

👆HERE   I    HAVE   USED   (**)   FOR   DESIGNING   INSTEAD   OF   THIS   U   CAN   USE ANYOTHER   TO   MAKE   IT   MORE   ATTRACTIVE .

     OUTPUT-  

👆HERE   YOU  CAN   👀ANALYSE  IN  THE   OUTPUT  THAT WHATEVER  WE HAD  WRITTEN  ABOVE  IN  THE  BRACKETS  IN  QUOTES  IT  IS NOW  SHOWN  IN  THE  OUTPUT.          

 TRY  IT  YOUSELF  !! : -

print("***************************************")                                                                      print("HELLO EVERYONE FOLLOW MY  BLOG!!!") print("***************************************") 

# NOW WE WILL PERFORM SOME SIMPLE MATHEMATICAL OPERATIONS:-(ADDITION , MULTIPLICATION , ) 

1) ADDITION : -

CODE-

👆HERE I WILL EXPLAIN U THE CODE LINE BY LINE:

1ST LINE AND 4TH LINE= ("**************)👈THIS IS USED AS DESIGNING. (OPTIONAL TO WRITE)

2ND LINE=("IF WE WILL ADD...)👈THIS WILL PRINT AS A SENTENCE TO KNOW WHAT WILL BE THE OUTPUT ABOUT.(OPTIONAL TO WRITE)

3RD LINE=(5+3)👈HERE I HAVE NOT USED QUOTES (" ") BECAUSE I DONT WANT IT AS IT TO BE PRINTED AS IT IS WRITTEN THEREFORE I HAVE WRITTEN IT WITHOUT QUOTES .  

OUTPUT-

👆HERE WHATAVER I HAVE WRIITEN IN QUOTES  IS PRINTED EXCEPT (5+3) AS IT BECAUSE I HAVENT PUT QUOTES BEFORE AND AFTER THEM. SO PYTHON HAS PERFORMED THE OPERATION OF ADDITION. I. E 5+3=8.

TRY  IT  YOUSELF !! : - 

print("**********************************")
print("IF WE WILL ADD 5 AND 3 WE WILL GET:")
print(5+3)
print("**********************************")

# IF  HAD WRITTEN  (5+3) IN QUOTES LIKE= ("5+3")

THEN THE CODE AND THE OUTPUT WILL BE:

CODE-

OUTPUT-

I HOPE NOW U HAVE UNDERSTOOD  THE DIFFRENCE OF WRITING SOMETHING IN QUOTES (" ")(' ') AND WRITING IT WITHOUT QUOTES ( ).

TRY  IT  YOUSELF !! : - 

print("***")
print("5+3")
print("***")

2) MULTIPLICATION : -

CODE-

IT  IS  ALL  SAME  AS  THE  ADDITION  PROGRAM  THE ONLY DIFFRENCE IS OF THE SIGN THAT IS (*) USED FOR MULTIPLICATION .

OUTPUT-

👆HERE IT HAS  PERFORM THE OPERATION OF MULTIPLICATION U CAN 👀ANALYSE IT FROM THE 3RD LINE OF CODE.

TRY  IT  YOURSELF !! : -  

print("**********************************")
print("IF WE WILL MULTIPLY 5 AND 3 WE WILL GET:")
print(5*3)
print("**********************************")

TRY  DIVISION  AND  SUBTRACTION ON  YOUR   OWN   IT  IS  THE  SAME  AS  ABOVE PERFORMED  OPERATIONS  THE   ONLY   DIFFRENCE   WILL   BE  OF  THE  SIGN
