def read_file(fn, *a, **kw):
with open(fn, *a, **kw) as f:
return f.read()
Usage:
script = read_file(".bashrc")
data = read_file("Ellalune_AlicePortrait.jpg", "rb")
decoded = read_file("greek.srt", encoding="ISO-8859-7")
If there's any problem with reading the file, an exception will be
raised. Also, thanks to the 'with' block, I'm guaranteed that the file
will have been closed before read_file() returns, which means I can
immediately go and write to the file without a conflict.
