Python direct path file printing issue? -


so have script needs print file in different directory. give absolute path , python doesn't it.

here's file located: c:\users\owner\documents\senior_design\qt_library\build-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\numbers.txt

(i know, long path, qt plotter makes file names long)

i typed:

textfile = open('c:\users\owner\documents\senior_design\qt_library\build-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\numbers.txt', 'w')

and error:

ioerror: [errno 22] invalid mode ('w') or filename:

i've read can use relative paths, unsure how give relative path many directories go through.

thanks!

the problem python interpreting backslashes in path escape sequences:

>>> 'c:\users\owner\documents\senior_design\qt_library\build-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\numbers.txt' 'c:\\users\\owner\\documents\\senior_design\\qt_library\x08uild-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\numbers.txt'

notice both \b , \n translated else. use "raw" string instead:

>>> r'c:\users\owner\documents\senior_design\qt_library\build-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\numbers.txt' 'c:\\users\\owner\\documents\\senior_design\\qt_library\\build-transmitterplot-desktop_qt_5_0_2_msvc2010_32bit-debug\\numbers.txt'

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
