Python Challenges - 1: Exercise-51 with Solution
Write a Python program that takes a string of numbers and letters and return string which consists of letters.
Sample Solution:
Python Code:
def decode(str1):
ints ="1234567890"
num = ""
letters = ""
result_string = ""
i = 0
while i < len(str1):
if str1[i] in ints:
num += str1[i]
else:
letters += str1[i]
i += 1
for i, char in enumerate(num):
result_string += int(char) * letters[i]
return result_string
print(decode("4A3B2C1D2A"))
print(decode("4A3B2C1D3A"))
print(decode("1P1H1P"))
print(decode("4A3B3C1D2A1B1D4A1C"))
