Python: Restore the original string by entering the compressed string with specified rule
Python Basic - 1: Exercise-58 with Solution
When character are consecutive in a string , it is possible to shorten the character string by replacing the character with a certain rule. For example, in the case of the character string YYYYY, if it is expressed as # 5 Y, it is compressed by one character.
Write a Python program to restore the original string by entering the compressed string with this rule. However, the # character does not appear in the restored character string.
Note: The original sentences are uppercase letters, lowercase letters, numbers, symbols, less than 100 letters, and consecutive letters are not more than 9 letters.
Multiple character strings are given. One string is given per line. Output:
The restored character string for each character on one line.
def restore_original_str(a1): result = "" ind = 0 end = len(a1) while ind < end: if a1[ind] == "#": result += a1[ind + 2] * int(a1[ind + 1]) ind += 3 else: result += a1[ind] ind += 1 return result print("Original text:","XY#6Z1#4023") print(restore_original_str("XY#6Z1#4023")) print("Original text:","#39+1=1#30") print(restore_original_str("#39+1=1#30"))
Original text: XY#6Z1#4023 XYZZZZZZ1000023 Original text: #39+1=1#30 999+1=1000
