Merge Into One

Three people each wrote part of a story in their own file. Time to put it all in one place.

Write merge_files(source_paths, target_path):

Read each file in source_paths, in the order given.
Write all of their text, one after another, into the file called target_path.
Read target_path back and return what it holds.

Don't add anything between the pieces. Just put them side by side.
If source_paths is empty, the target file should be empty.
Use with for every file you open.

Leave the make_file helper as it is.

Examples

source_paths = [make_file('p1.txt', 'Once '), make_file('p2.txt', 'upon a time')]

target_path = 'story.txt'

returns 'Once upon a time'

source_paths = [make_file("mg_a1.txt", "ab"), make_file("mg_a2.txt", "cd")]

target_path = "mg_a_out.txt"

returns 'abcd'

source_paths = [make_file("mg_b1.txt", "only one")]

target_path = "mg_b_out.txt"

returns 'only one'
