tama kaya to? hahah testing di ko masyado alam python

print('\n\n Display the sum of the series [ 9 + 99 + 999 + 9999 ...]')
print(' -------------------------------------------------------------\n')
num = int(input("Input number of terms: "))
sum = 0
k = 9
for i in range(0,num,1):
sum=sum*10+9

print(sum,end=" + ")
print()

# SOLUTION 1: Print the series with space separator like in your example.
def solution1():
    print('Display the sum of the series [ 9 + 99 + 999 + 9999 ...]\n')
    print('---------------------------------------------------------\n')
    t = 9
    s = 0
    n = int(input('Input number of terms: '))
    for _ in range(n):
        s += t
        print(t, end=' ')
        t = t * 10 + 9
    print(f'\nThe sum of the series = {s}')

OUTPUT:

Input number of terms: 5
9 99 999 9999 99999
The sum of the sarise = 111105

# SOLUTION 2: Print the series inside the loop with + separator
def solution2():
    print('Display the sum of the series [ 9 + 99 + 999 + 9999 ...]\n')
    print('---------------------------------------------------------\n')

    t = 9
    s = 0
    n = int(input('Input number of terms: '))

    for _ in range(n):
        s += t
        print(t, end=' + ')
        t = t * 10 + 9

    print('\b\b ')  # remove the last (+) separator
    print(f'\nThe sum of the series = {s}')

# SOLUTION 3: Add the series to list then print outside the loop with + separator (mas Pythonic way than the solution 2)
def solution3():
    print('Display the sum of the series [ 9 + 99 + 999 + 9999 ...]\n')
    print('---------------------------------------------------------\n')
    t = 9
    s = 0
    n = int(input('Input number of terms: '))
    series = []
    for _ in range(n):
        s += t
        series.append(t)
        t = t * 10 + 9
    print(*series, sep=' + ')
    print(f'\nThe sum of the series = {s}')

SOLUTION 2 AND 3 OUTPUT:

Input number of terms: 5
9 + 99 + 999 + 9999 + 99999

The sum of the series = 111105
