[Python] [19] [demo experimental practice examples] [different-digit Arabic numerals and the same number of]

Original title:

Seeking s = a + aa + aaa + aaaa + aa ... the value of a, where a is a number. E.g. 2 + 22 + 222 + 2222 + 22222 (in this case the sum total of the number 5), the number added by several keyboard.

 

My code:

# ! / Usr / bin / Python 
# encoding = UTF. 8- 
# - * - Coding: UTF-. 8 - * - 

#   find s = a + aa + aaa + aaaa + aa ... the value of a, where a is a digital. E.g. 2 + 22 + 222 + 2222 + 22222 (in this case the sum total of the number 5), the number added by several keyboard. 

X = int (INPUT ( " Please The INPUT Number X: \ n- " ))   # input to 2 shown above problems 
Y = int (INPUT ( " Please The INPUT Number Y: \ n- " ))   # input as title to 5 FIG 
S1 = 0 
S = 0 # for counting all sum; 
IF X in [1,2,3,4,5,6,7,8,9 ]:
     IF Y> =. 1 and Y =%. 1 = 0:
        for i in range(1,y+1):
            s1 = s1 + x * 10 ** (i-1)
            s = s + s1
            print(s,s1)
print("###",s)
        

 

Too simple, nothing can be explained;

 

Original answer questions given relatively simple;
