Description:
 def append_code(original, codefile):
 """Append the contents of one file to another. :param original: name of file that will be appended to :type original: str :param codefile: name of file that will be appende :type codefile: str This function is particularly useful when one wants to replace a function in student code with their own implementation of one. If two functions are defined with the same name in Python, the latter definition is taken so overwriting a function is as simple as writing it to a file and then appending it to the student's code. Example usage:: # Include a file containing our own implementation of a lookup function. check50.include("lookup.py") # Overwrite the lookup function in helpers.py with our own implementation. check50.py.append_code("helpers.py", "lookup.py") """

    with open(codefile) as code, open(original, "a") as o:
        o.write("\n")
        o.writelines(code)
