Today's Freebie. It's marked as easy.

This problem was asked by Amazon.

Run-length encoding is a fast and simple method of encoding strings. The basic idea is to represent repeated successive characters as a single count and character. For example, the string "AAAABBBCCDAA" would be encoded as "4A3B2C1D2A".

Implement run-length encoding and decoding. You can assume the string to be encoded have no digits and consists solely of alphabetic characters. You can assume the string to be decoded is valid.

def encode(input):
out = ""

let = input[0]
num = 1

for i in range(1, len(input)):
if input[i] == input[i-1]:
num = num + 1
else:
out = out + str(num) + input[i-1]
let = input[i]
num = 1

out = out + str(num) + input[len(input)-1]

return out

def decode(input):
out = ""

i = 0

while i != (len(input)):
for p in range(0, int(input[i])):
out = out + input[i+1]
i = i + 2

return out

@matrix07012 not sure how you feel about criticism, so I will hold back too much opinion. However, line 4 and 12 are unused.
