Checking whether pip is installed?

Question

I am using Python 2.7.12 and I want to check whether the pip is installed or not. For this, in command line of Python application I wrote pip list and pressed enter. However, I get an error like:

File"stdin",line 1  pip list  Syntax Error: invalid syntax 

So, how can I solve this issue and get the list of modules as an output?

Thanks

Answer 1

Use command line and not python.
TLDR; On Windows, do:
python -m pip --version
OR
py -m pip --version

Details:

On Windows, ~> (open windows terminal)
Start (or Windows Key) > type "cmd" Press Enter
You should see a screen that looks like this
To check to see if pip is installed.

python -m pip --version 

if pip is installed, go ahead and use it. for example:

Z:\>python -m pip install selenium 

if not installed, install pip, and you may need to
add its path to the environment variables. (basic - windows)
add path to environment variables (basic+advanced)

if python is NOT installed you will get a result similar to the one below

Install python. add its path to environment variables.

UPDATE: for newer versions of python replace "python" with py - see @gimmegimme's comment and link https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/

Answer 2

$ which pip 

or

 $ pip -V  

execute this command into your terminal. It should display the location of executable file eg. /usr/local/bin/pip and the second command will display the version if the pip is installed correctly.
