Opening a File Outside PyCharm IDE - Read Line by Line
Hello...
Let me begin by saying that I'm new to Python and to PyCharm. I'm using Python 3.3.3 and PyCharm 3.0.2 CE on Mac OS X Mavericks. I have a text file that I would like to read line by line. The file itself can be very large at times. Of course I've researched as much as I can using all the familiar search engines with no luck before creating this post. This is how I'm trying to reference the file I wish to read line by line:
text_file = os.path.isfile("/<user>/Documents/my_file.txt")
#do something to each line in the text file
I get the following error message:
FileNotFoundError: [Errno 2] No such file or directory: '/<user>/Documents/my_file.txt'
Could anyone recommend the proper method I should use to read a text file line by line I'm referencing in PyCharm? I apologize if a previous post has been created asking the same question. Any suggestions would be helpful. Thank you!

- Open the terminal
- ls /<user>/Documents/my_file.txt
Make sure that you copy & paste the exact same path from the error message. If it prints out ls: /<user>/Documents/my_file.txt: No such file or directory, then there is either a subtle typo in the path to the file or the file really does not exist.To read the text file, you could just do something like this:
fname = '/<user>/Documents/my_file.txt' if os.path.isfile(fname): println("Found file '{}'".format(fname)) with open(fname, 'r') as f: for line in f: print linePlease note that os.path.isfile returns a whether the path is a file or not and stores it in text_file. This is not the variable you'd want to use in the open call (because it's not the path).
file=open("/root/exact path of the fileand with extension")
print(file.read())
with out module it will work
NOTE:check the uppercase and lowercase of the file while giving path
