Program to add two constant number

In this program, we can take two variables and assign a value on them and perform addition.

#Addition of Integer value
a=5
b=10
print("Total sum of a and b is:",a+b)

#Addition of float value
a=5.234
b=10.432
print("Total sum of a and b is:",a+b)

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
Total sum of a and b is: 15
Total sum of a and b is: 15.666
Process finished with exit code 0

Addition of two user input Number

x=input("enter value of x:")
x=int(x)           # Type connversion
y=input("enter value of y:")
y=int(y)            # Type connversion
z=x+y                # Adding X and Y
print("sum of x and y is:",z)# Result of Sum

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter value of x:4
enter value of y:7
sum of x and y is: 11
Process finished with exit code 0

Addition of Number using while loop

num=int(input("enter number:"))
# Here type conversing and taking input from user

total=0
i=1

while i <= num:
  total+=i
  i+=1
print("total sum is:",total)

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter number:5
total sum is: 15
Process finished with exit code 0

Addition of Number using for loop

n = int(input("Enter number"))
sum = 0
# loop from 1 to n
for num in range(1, n + 1, 1):
    sum = sum + num
print("Sum of first ", n, "numbers is: ", sum)
avg = sum / n
print("Average of ", n, "numbers is: ", avg)

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
Enter number5
Sum of first  5 numbers is:  15
