Print function with different examples in detail

program45_-rt8nb

Print statement in python is not reserved word nor a statement. Print is built in function call which run as expression statement.

The interactive session automatically prints the results of expressions you type, you don’t usually need to
say “print” explicitly at this prompt:

>>>ethosspace = 'Testing Services'
>>>ethosspace  
' Testing Services '

So print function used in files not on interactive prompt.

Syntax
print([object, …][, sep=’ ‘][, end=’\n’][, file=sys.stdout])

print(object(s), sep=separator, end=end, file=file, flush=flush)

Items in square brackets are optional and may be omitted in a given call, and values after = give argument defaults.
In English, this built-in function prints the textual representation of one or more objects separated by the string sep and followed by the string end to the stream file.

SEP is a string inserted between each object’s text, which defaults to a single space if not passed; passing an empty string suppresses separators altogether.

END is a string added at the end of the printed text, which defaults to a \n newline character if not passed. Passing an empty string avoids dropping down to the next output line.

FILE specifies the file, standard stream, or other file-like object to which the text will be sent; it defaults to the sys.stdout standard output stream if not passed.

Here are the real time example of print function.

print function with no parameter print the empty line

>>>print()

To print blank line no need to pass any parameter by default print without any parameter prints blank line.

>>> a=9
 >>> b='Testing'
 >>> c=['Prog']
 >>> print(a,b,c)
         9 Testing ['Prog']

So while printing 3 objects print function added empty space between those three objects. So in place of empty space if we want different separator then we can use below syntax.

 >>> print(a,b,c,sep=' => ')
          9 => Testing => ['Prog']

Output is now separated with separator => which we provided.

By default, print adds an end-of-line character to terminate the output line. 

>>>print ('ethosspace'); print('leading software testing provider')
        ethosspace
        leading software testing provider

So if we don’t need new line then we will use end parameter here

>>>print (‘ethosspace’,end=”); print(‘ leading software testing provider’)

ethosspace leading software testing provider

Example of variable, %d and % in print statement. Use of variable in between sentence in print statement.

>>>x=5
>>>y=8
>>>z=2 * (x+y)
>>>print('A rectangle %d by %d has a perimeter of %d units.'%(x,y,z))
A rectangle 5 by 8 has a perimeter of 26 units.

C Program to calculate total Body Mass Index BMI with weight and height

program45_-rt8nb 2 Comments

Body Mass Index is a simple calculation using a person’s height and weight. To calculate BMI we can use the formula BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in meters squared. Here is a complete C program code to calculate BMI in float value with 2 decimal places.

/* C Program to print BMI based on formula */
#include <stdio.h>
int main()
{
    float wt,ht,bmi;
    printf("\n\t Enter Weight In Kg\t");
    scanf("%f",&wt);
    printf("\n\t Enter height In Meters\t");
    scanf("%f",&ht);
    //Calculate BMI 
    bmi = wt / (ht*ht);
    if (bmi <= 18.5)
    {
        printf ("BMI Report is : %.2f -> Underweight", bmi);
    }else if(bmi <= 24.9)
    {
        printf("BMI Report is :  %.2f -> Normal",bmi);
    }
    else if(bmi >= 25 && bmi <= 29.9)
    {
        printf("BMI Report is : %.2f -> Overweight",bmi);
    }
else
   printf("BMI Report is : %.2f -> Obese",bmi);   
    return 0;
}

Output after after calculating body mass index using c program is below

Enter Weight In Kg	70
Enter height In Meters	2
BMI Report is : 17.50 -> Underweight

Programs to print different Square, rectangle in Python Language

program45_-rt8nb

Below program will accept width and breadth from user. We can print SOLID rectangle, need to use two for loops along with print function with end parameter.

Step 1) Accept breadth and width from user
Step 2) First for loop is to print 

#Python program to print hollow rectangle, solid rectangle.
#accept width and breadth from user
width=int(input("Enter Width\t"))
breadth=int(input("Enter breadth \t"))
for i in range(0,breadth):
    for j in range(0,width):
        print("*",end="")
    print()

OUTPUT

Enter Width	5
Enter breadth 	3

Python Program to print hollow rectangle

This tricky program. It is important to use print function along with end parameter effectively. Here is the complete code

#Python program to print hollow rectangle
#accept width and breadth from user
width=int(input("Enter Width\t"))
breadth=int(input("Enter breadth \t"))
for i in range(0,breadth):
    for j in range(0,width):
        if (i==0 or j ==0 or i==breadth or j==width):
             print(" *",end="")
        else:
             print(" ",end="*")

Print hollow square using for loop for user input length.

Steps to build this program
1) Accept length from user
2) First for loop to iterate pointer row wise
3) second inner for loop for to iterate pointer column wise
4) IF statement to compare first and last row for printing star
5) Else condition to print star for first and last column of every row.

Here is the complete code

/* C Program to print Hollow SQUARE  */

#include <stdio.h>

int main()
{
    int i, j, len;

    // Get Length of square from user 
    printf("Enter length of square: ");
    scanf("%d", &len);
    printf("\n");
 // This for loop to change pointer row wise
    for(i=1; i<=len; i++)
    {
        //This for loop to print *
        for(j=1; j<=len; j++)
        {
            //condtion to print all star for first and last line
            //Also to print first and last star of evey line
            if (i==1 || i == len || j ==1 || j == len)
            {
                printf(" *");
            } 
            //this else part to print blank for rows between 1 and n
            else
            {
                printf("  ");
            }
        }
        printf("\n");
    }
    return 0;
}

Output

Enter length of square: 8

Printing spaces can be handled. By providing extra spaces in print statement we can print suitable hollow square

Program to identify and print perfect number in C Language

program45_-rt8nb

This C Program is for to identify perfect number. Here program is accepting range up to which need to identify perfect number. Perfect number is  a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. for example 6 where it is divisible for 1, 2, 3 so sum of it is 6. To write this program we have used two for loop along with simple if condition.

// Program to find perfect number
#include <stdio.h>

int main() {
    // Write C code here
    int rangeNo,counterNo,perSum;
  
    printf("\n\tEnter Range to find perfect number \t");
    scanf("%d",&rangeNo);
   //Loop to find divisible numbers 

    for (int i = 1;i<=rangeNo;i++)
    {
        perSum=0;
          for (int j = 1;j<i;j++)
            {
                if (i%j == 0)
                perSum = perSum + j;
             }
            if (perSum == i)
            printf("\n\t %d is perfect number ",i);
    }
    return 0;
}

Output

Enter Range to find perfect number 	10000
6 is perfect number 
28 is perfect number 
496 is perfect number 
8128 is perfect number

rangeNo = int(input("\n\tEnter number upto which you need to find number divisible by 3 or 5\n\t"))

#Loop to print numbers divisible by 3
print('\n\nThese numbers are divisible by 3 upto %d'%rangeNo)
for i in range(1,rangeNo+1) :
    if (i%3 ==0):
        print("\t%d"%i)
        
#Loop to print numbers divisible by 5
print('\n\nThese numbers are divisible by 5 upto %d'%rangeNo)
for i in range(1,rangeNo+1) :
    if (i%5 ==0):
        print("\t%d"%i)
