I have a program: decrypt2.py which contains this function:
def scramble2Decrypt(cipherText):
halfLength = len(cipherText) // 2
oddChars = cipherText[:halfLength]
evenChars = cipherText[halfLength:]
plainText = ""
for i in range(halfLength):
plainText = plainText + evenChars[i]
plainText = plainText + oddChars[i]

FYI, this can be shortened to:
plainText = cipherText[0 : : 2] + cipherText[1 : : 2]
