HowTo Read File in Python Interpreter?

Question

I want to

f = open("~/jobs/2014-12-16/output/output.log", "r")

in Python interactive Shell. How?

Getting:

IOError: [Errno 2] No such file or directory: '~/jobs/2014-12-16/output/output.log'

Without path it works if Interpreter started in parent working directory.

I don't think ~ works here, see: stackoverflow.com/questions/4028904/… — chrki

There's no (well, very little) difference between interactive python and non-interactive python. Your problem is that the file does not exist, as stated in the error message. Python does not automatically expand the ~ character in paths, you have to use the os.path.expanduser function for that.

f = open(os.path.expanduser("~/jobs/2014-12-16/output/output.log"), "r")

You need to tell Python to deference the ~ character via os.path.expanduser.

full_path = os.path.expanduser("~/jobs/2014-12-16/output/output.log")
f = open(full_path, 'r')
