Gosh, how did I miss that, that the mode is a string. Well it had to be
something simple like that. Quoting the w and r fixed the problem. Very
embarrassing.

Thanks,

following:
I want to store a little data on the eMMC from my Python code. My program
is not getting errors when I try to write a very short data file but it
doesn't actually seem to write it as I cannot read it back. I am using
f = open('MyFile.txt', w)
First problem -- the mode is a string...
f = open("MyFile.txt", "w")
or
f = open('/home/debian/Desktop/MyFile.txt', w)
or
f = open('MyFile.txt', r)
or
f = open('/home/debian/Desktop/MyFile.txt', r)
to open the file and am not getting any errors but Python is not finding
the file and I cannot find the file with a search from WinSCP.
Did you ever write anything to the file, and did you close the file?
f.write("Some junk\n")
f.close()
The first open should create the file in whatever your current working
directory is. Without connecting my BBB I can't confirm if the second is a
valid path.
And last -- how are you running it? SSH to a command line?
