Please answer in Python (no imports, no list comprehensions)

Given a file with an encoded message, parse through it line by line and return a decoded version of the file in one string, with each decoded message in a new line. Dont remove the extra empty line (last line) from the output string.

while decoding, ignore: all exclamation points (!), question marks (?), semicolons (;), dollar signs ($) and any whitespaces.

For example:

if input = "2!03!!!4 $el!;k?in ??s!tre!$$et" ; output = "2034 elkin street"

def decode(file): """ >>> print(decode('files/encoded_1.txt').strip()) stevie wonder 2 #4 b#l3o()% m@^^^& ave Ffsdf812*2&@&#*1 Lafayette Street 32'1 fulleH##r "dr^i~v@e @&*(@@&&&@#& 8/09 1-2 >>> print(decode('files/encoded_3.txt').strip()) """
