Python Code to Calculate Sum of Concatenated Integers

This code takes an input 'x' and calculates the sum of all the numbers formed by concatenating consecutive integers up to 'x'. For example, if 'x' is 3, the sum would be 123 + 12 + 3 = 138.

x = int(input())
if x < 0 or x > 6:
    print('Date error!')
else:
    sum = 0
    for i in range(1, x+1):
        data = ''
        for j in range(1, i+1):
            data = data + str(j)
        sum = sum + int(data)
    print(sum)

The code iterates from 1 to 'x' and for each number 'i', it creates a string 'data' by concatenating integers from 1 to 'i'. This string 'data' is then converted to an integer and added to the 'sum'. Finally, the 'sum' is printed.
