Afterwards, in IDLE shell try importing nltk: import nltk.

pip3 uses the Python 3 version of pip (Macs ship with Python 2 by default, and pip defaults to Python 2.)

This automatically downloads and installs the most current version of NLTK.

#PYTHON 3 INSTALL BLTK INSTALL#

Depending on your system, you might need to use sudo with the command: sudo pip3 install -U nltk.

In a Terminal window ( what is Terminal?), run pip3 install -U nltk.

The procedure is more or less the same as what's on the "Installing NLTK" page, with some extra steps.

How do I work with CWD (current working directory) in Python shell?.

A final note: if you are working in IDLE, bear in mind that executing a script changes your IDLE shell's CWD to your script's directory.

#PYTHON 3 INSTALL BLTK HOW TO#

See this screen shot and and the next FAQ for how to work with your CWD setting in Python shell.

(Not recommended, since your shell's CWD may change.)

Change your CWD to the file's directory, or.

In your shell, the initial CWD setting varies by system. Therefore, you can refer to a file in a script by its name only provided that the file and the script are in the same directory.

When you execute your script, your CWD is set to the directory where your script is. To complicate the matter, your Python has different initial CWD settings depending on whether you are working with a Python script or in a shell environment. Basically, referring to a file without specifying its path ( 'myfile.txt') works only when the file is in your CWD. The concept of Current Working Directory (CWD) is crucial here.

How do I find its full file path and name? I have this file sitting in my Desktop/My Documents.That way, everything in the string is interpreted as a literal character, and you don't have to escape every backslash. Alternatively, you can prefix the entire file name string with the rawstring marker "r": r'C:\Users\narae\Desktop\foo.txt'.If using backslash, because it is a special character in Python, you must remember to escape every instance: 'C:\\Users.Therefore, you can refer to the file as 'C:/Users/narae/Desktop/foo.txt'. Python simply lets you use OS-X/Linux style slashes "/" even in Windows.In Python, Windows files can be referred to in multiple ways: They start with the disk label "C:", and backslashes are used to separate directories. Windows file paths look like this: C:\Users\narae\Desktop\foo.txt. They start from the root "/", and slashes are used to separate directories. OS-X/Linux file paths look like this: /Users/narae/Desktop/foo.txt. (Win) My file names show up without the extensions (.txt.

#PYTHON 3 INSTALL BLTK CODE#

It should open right up in your own Python code directory.

When you are done, open up your Python IDLE.

It will ask "Save modified buffer?" Type Y and enter. Os.chdir(os.path.expanduser('~/Documents/pythoncode')). Os.chdir(os.path.expanduser('~/Documents')).Įdit the line to add your subfolder name, e.g., : Move to the 8th line using the arrow key, which is:

A file editing window will then open up.

The sudo command ('super user do') lets you execute a command as a super user.

Now, you have to edit idlemain.py using a program called nano.

Move into the IDLE app setting directory, using the cd ('change directory') command:Ĭd /Applications/Python\ 3.8/IDLE.app/Contents/Resources.

It is under the "Utilities" directory in "Applications", in Finder. Preferably, give it a one-word name (without a space), such as "pythoncode". The default directory is also where your Python looks for modules and other files, so that's an added bonus beyond having your script files neatly organized.

Changing IDLE's default directory is a great idea.
