What is the best way to read a file using the read mode 'rU' (read a file with universal newline support) in an elegant way in Python 2 and 3? Py3.4 has recently deprecated this, causing DeprecationWarings:
with open(filename, 'rU') as handle:
content = handle.read()
I don't see a way to call open()
with a clever mix of arguments to make it work for both. I'd wrap it in a helper method which distinguishes between Python 2 and 3:
import sys
if sys.version_info[0] == 2:
def open_text(filename):
return open(filename, 'rU')
else:
def open_text(filename):
return open(filename, 'r', newline=None)
