# Python Program of Basic Questions (Part-2)

### 1. Write a Python program to print the following string in a specific format.

``````p='Twinkle, twinkle, little star,\n   How I wonder what you are!\n      Up above the world so high,\n      Like a diamond in the sky.\nTwinkle, twinkle, little star,\n   How I wonder what you are'
print(p)``````

Output:

``````Twinkle, twinkle, little star,
How I wonder what you are!
Up above the world so high,
Like a diamond in the sky.
Twinkle, twinkle, little star,
How I wonder what you are``````

### 2. Write a Python program that read a string from a user and print the sting in double quotation marks.

``````str=input("Enter a string= ")
print('""',str,'""')``````

Output:

Enter a string= I Am Coding Lover
“” I Am Coding Lover “”

### 3. Write a Python program which accepts the radius of a circle from the user and compute the area.

``````r=int(input("Enter radius of circle= "))
area= 22/7*(r*r)
print("Area of Circle= ", area, "sq")``````

Output:

Area of Circle= 113.14285714285714 sq

### 4. Write a Python program that will accept the base and height of a triangle and compute the area.

``````b=int(input("Enter base of triangle= "))
h=int(input("Enter height of triangle= "))
area= 1/2*b*h
print("Area of Triangle= ", area)``````

Output:

Enter base of triangle= 4
Enter height of triangle= 6
Area of Triangle= 12.0

### 5. Write a Python program to perform swapping of two numbers with or without third variable.

``````a=int(input("Enter a value of A= "))
b=int(input("Enter a value of B= "))
a=a+b
b=a-b
a=a-b
print("Value of A= ", a, "\nValue of B= ",b)``````

Output:

Enter a value of A= 55
Enter a value of B= 99
Value of A= 99
Value of B= 55

### 6. Write a Python program that read a 3 digit number from user and perform the addition of their digits.

``````a=int(input("Enter a 3 Digit Number = "))

if a>100 and a<999:
x=a//100
y=(a-x*100)//10
z=a-x*100-y*10
print("Sum of Your 3 Digit Number= ", x+y+z)
else:
print("SORRY!!! Please Enter Only 3 Digit Number")``````

Output:

Enter a 3 Digit Number = 578
Sum of Your 3 Digit Number= 20

### 7. Write a python program to find the greatest number among three.

``````a=int(input("Enter a Number = "))
b=int(input("Enter a 2nd Number = "))
c=int(input("Enter a 3rd Number = "))

if a>b and a>c:
print(a," is greatest number")

elif b>a and b>c:
print(b," is greatest number")

else:
print(c, " is greatest number")``````

Output:

Enter a Number = 777
Enter a 2nd Number = 950
Enter a 3rd Number = 586
950 is greatest number

### 8. Write a python program to display a greet message according to the marks obtained by the student.

``````a=int(input("Enter Your Marks in % = "))

if a>=90 and a<=100:
print("Excellent")

elif a>=70 and a<=90:
print("Very Good")

elif a>=60 and a<=70:
print("Good")

elif a>=40 and a<=60:
print("Hard Work Needed")

elif a>=0 and a<=40:
print("Better Luck Next Time")

else:
print("SORRY!!! Please Inter Valid Marks in %")
``````

Output:

Enter Your Marks in % = 90
Excellent

### 9. Enter basic salary from the user. Write a program to calculate DA and HRA on the following conditions:-Salary DA HRA<=2000 10% 20%>2000 && <=5000 20% 30%>5000 && <=10000 30% 40%>10000 50% 50%

``````a=int(input("Enter Your Salary = "))

if a<=2000:
da=a*10/100
HRA=a*20/100

elif a>2000 and a<=5000:
da = a*20/100
HRA = a * 30 / 100

elif a>5000 and a<=10000:
da = a * 30 / 100
HRA = a * 40 / 100

elif a>10000:
da = a * 50 / 100
HRA = a * 50 / 100
