In this lecture we are discussing about numpy arrays and how to install numpy in pycharm and cmd:

-- If you want to work with multidimension arrays

from array('i', [1,2,3],[4,5,6])
print(arr) # you get error

-- array which are using not supporting multidimension arrays
-- thats why you need to use numpy arrays which are supporting multidimension arrays
-- by default numpy are not installed in python

Install numpy from cmd:
-- you need to install numpy using pip install numpy
-- install using command pip install numpy in cmd(command prompt)

Install numpy in pycharm:
-- in pycharm we need use shortcut ctrl+alt+s and simply going to setting
-- and then going to project interpreter and then click on + sign and search numpy and install it

from numpy import * #importing numpy
arr=array([1,2,3,4,5,6])
print(arr)

not all superheroes wear capes, some teach Python for free..

For those getting error in cmd while installing numpy try any of the following commands but make sure ur internet is connected
1) 'py -m pip install numpy' OR
2) 'python -m pip install numpy' OR
3) 'py -m pip3 install numpy' OR
4) 'python -m pip3 install numpy'

Any one of the above 4 should work based on the python version u have
If further it is asking to upgrade pip version then use this command in cmd to upgrade pip
'-m pip install --upgrade pip'

Folks - Whoever is getting an error "pip3 or pip is not a recognized internal or external command" needs to watch Episode#7. Navin has actually shown exactly how to set the path for python or scripts in command prompt. The path needs to be added in the environmental variables. I was getting that error too and went back to that video and set the path. After that, the installation is a breeze. Hope this helps!

Many thanks.. What a great teacher you are! 🙏🙏.. This is the sign of a great teacher.. After learning.. almost everything becomes clear and can do by own.. Lots of respect..

[silvipriya]

For everyone getting error like 'PIP is not a recognized internal or external command', please add the location of PIP which is <directory where python is installed>/Scripts [for eg:- if python is in C folder then C:/User/<name of user>/Python37/Scripts] in your windows environmental variable. Then restart your command prompt and then things will work.

Once again u nailed the teaching. Ur way of teaching motivates to learn more without any boredom.

I had problem at the moment of installing numpy in Pycharm. It asks me for installing C++ and other things. The problem was solved when I went to the terminal of Pycharm, uninstalled pip, and reinstalled pip. Automatically pip was installed at the version 20.0.2 and not in the previous version 19.... that obviously was generating some error. Then I proceed to install numpy, and it worked. At least, It was my way of solving it. I hope it helps you. Navin is the best.

[sreekanthreddy]

sir, Are you going to start Artificial Intelligence or machine learning after completion of python series

[nikunjdewan]

sir India needs more teachers like you

Thank you very much, greetings from Ukraine.

For people using macs, it didn't work when I typed "pip3 install numpy", but it worked when I said "pip install numpy" without the 3

Here's a slight reiteration incase someone gets confused with array initialization.

Method 1 - Numpy as np=>
import numpy as np
arr = np.array([1, 2, 3], dtype=int)
or
arr = np.array([1, 2, 3])

Method 2 - import array module from numpy=>
from numpy import *
arr = array([1, 2, 3], dtype=int)

Method 3 - import array module from array=>
from array import *
arr = array(typecode='i', [1, 2, 3])

Notice:
In method 2 and method 3 the array module is imported from different package. So their initailaization differs.
Also the dtype parameter in 'numpy.array' is optional, unlike the typecode paramater in 'array.array' which is required.
