Installing packages in Python

Before we start installing any packages, we need to install PYTHON and PIP on windows.

• Download python from this link. You can choose from different versions.
• Run the .exe file. 
• Don't forget to check "Add Python to environment variables" checkbox.
• After installing python. to verify if its installed correctly or not, open command prompt and type python. If it is installed properly, you'll see this window.

Successful installation of Python

• Now its time to install to install PIP.
• To install PIP, download get-pip from here . Right on it and save as get-pip.py. Or copy everything and paste it in a notepad file then save it as get-pip.py.
•  Open cmd in the folder where you have downloaded the get-pip.py file and type:
• python get-pip.py
• Sometimes py get-pip.py works instead of the above command.
• It will install the PIP on your windows.
• After it's installed successfully, you can start installing other packages using pip command:
• pip install numpy
• pip install pandas
• pip install matplotlib
