    your standard download folder.

  4. Move this file to a more permanent location, so that you can install Python
    (and reinstall it easily later, if necessary).
  5. Feel free to explore this webpage further; if you want to just continue
    the installation, you can terminate the tab browsing this webpage.

  6. Start the Installing instructions directly below.


  1. Double-click the icon labeling the file python-3.7.4-amd64.exe.

    A Python 3.7.4 (64-bit) Setup pop-up window will appear.

    Ensure that the Install launcher for all users (recommended) and the
    Add Python 3.7 to PATH checkboxes at the bottom are checked.

    If the Python Installer finds an earlier version of Python installed on
    your computer, the Install Now message may instead appear as
    Upgrade Now (and the checkboxes will not appear).

    click it.

  3. Click the Yes button.

    A new Python 3.7.4 (64-bit) Setup pop-up window will appear with
    a Setup Progress message and a progress bar.

    During installation, it will show the various components it is installing
    and move the progress bar towards completion.
    Soon, a new Python 3.7.4 (64-bit) Setup pop-up window will appear
    with a Setup was successfuly message.

  4. Click the Close button.

Python should now be installed.


To try to verify installation,

  1. Navigate to the directory
    (or to whatever directory Python was installed: see the pop-up window
    for Installing step 3).
  2. Double-click the icon/file python.exe.

    The following pop-up window will appear.

    A pop-up window with the title
    appears, and inside the window; on the first line is the text
    Python 3.7.4 … (notice that it should also say 64 bit).
    Inside the window, at the bottom left, is the prompt >>>: type
    exit() to this prompt and press enter to terminate Python.

    You should keep the file python-3.7.4.exe somewhere on your computer in
    case you need to reinstall Python (not likely necessary).

    You may now follow the instructions to download and install Java (you should
    have already installed Java, but if you haven’t, it is OK to do so now, so
    long as you install both Python and Java before you install Eclipse), and
    then follows the instruction to download and install the Eclipse IDE.
    Note: you need to download/install Java even if you are using Eclipse only
    for Python)
