  • 解答は基本的に，下記 5 行の関数です． 

def sum_of_range( start, end ):
    sum = 0
    for i in range( start, end + 1 ):
        sum += i
    return( sum )
  • 【別解】
    • 以下の部分は，当然ですが，べき乗で表現することもできます． 

# ----- 計算と結果の表示 ----
x = 1
for i in range( 5 ):
    x *= 10
    print( sum_of_range( 1, x ) )


# ----- 計算と結果の表示 ----
for i in range( 1, 5 ):
    print( sum_of_range( 1, 10 ** i )
