Sololearn Sum Of Consecutive Numbers Update

To find the sum of consecutive numbers in Sololearn, you can use a loop to iterate through each number in the sequence and add it to a running total.

Here’s an example program that asks the user for a starting number and an ending number, and then calculates the sum of all the numbers between them:

sql
start = int(input("Enter the starting number: "))
end = int(input("Enter the ending number: "))

total = 0
for i in range(start, end+1):
    total += i

print("The sum of consecutive numbers between", start, "and", end, "is:", total)

In this program, we first ask the user to enter the starting and ending numbers. We then initialize a variable total to 0 to keep track of the running total.

We then use a for loop with the range function to iterate through all the numbers between the starting and ending numbers (inclusive). For each number i, we add it to the running total total using the += operator.

Finally, we print out the sum of consecutive numbers between the starting and ending numbers using the print function.

You can use a while loop in Python to find the sum of consecutive numbers. Here’s an example:

python
# Get input from user
n = int(input("Enter a positive integer: "))

# Initialize variables
sum = 0
i = 1

# Use while loop to calculate sum
while i <= n:
    sum += i
    i += 1

# Print the result
print("The sum of the first", n, "positive integers is", sum)

In this example, the program prompts the user to enter a positive integer. It then initializes two variables: sum, which will hold the running total of the sum of consecutive integers, and i, which starts at 1 and will be used to iterate through the integers from 1 to n.

The while loop continues as long as i is less than or equal to n. During each iteration of the loop, the current value of i is added to sum, and i is incremented by 1. After the loop has completed, the program prints the result.

For example, if the user enters 5, the program will calculate the sum of the first 5 positive integers (1 + 2 + 3 + 4 + 5) and output:

python
The sum of the first 5 positive integers is 15

To find the sum of consecutive numbers in Python using the range() function, you can use a loop to iterate over the range of numbers and add them up. Here is an example code snippet:

python
start = 1
end = 10

# Using a loop to iterate over the range of numbers and add them up
total = 0
for num in range(start, end+1):
    total += num

print("The sum of consecutive numbers from {} to {} is {}".format(start, end, total))

In this example, the start variable is set to the first number in the sequence, and the end variable is set to the last number in the sequence. The loop iterates over the range of numbers from start to end+1 (inclusive) using the range() function, and adds each number to the total variable. Finally, the sum is printed using the print() function with a formatted string.
