Introduction to Programming and Python

facing error while opening the juyter notebook for python

Hi when i use the command to use Python in Web Console.It is showing error:

[roopamambekar149820@cxln4 ~]$ export PATH=/usr/local/anaconda/bin:$PATH

[roopamambekar149820@cxln4 ~]$ source activate py36

Could not find conda environment: py36

You can list all discoverable environments with `conda info --envs`.

Dear Team, similar to how we could access the files in the Linux course via WSL on my laptop, is there anyway to access CloudXLab's Jupyter notebook via my computer's cmd? 

Hey I have a question about why x = 1 + 2 ** 3 / 4 * 5
print (x) resolves to x as 11

According to the order of operations follwoing the PEMDAS rule, after solving for parantheses and exponents is followed by solfing multiplication and then division, but in this case after calculating 2**3, the next operation should be 4*5, why is 8/4 prioritized?

while trying to run the code
n = 5
while n>0:
    print('n')
    n = n-1
    print('Blastoff')

Output am getting is

n
Blastoff
n
Blastoff
n
Blastoff
n
Blastoff
n
Blastoff

Please correct me where am going wrong.

can you please tell me exact wat to use console..which path need to export

As I go on the services tab and try to open web console, there's nothing but blank screen and a message that browser failed to open the page. I tried logging out and then logginf In again but couldn't open it.

Raj,

Again and again, I'm facing difficulties, kindly shorten the resolution time so that I can use my time efficiently , I've other stuff to do as well. I can't devote my full day in this job of typing the error to you, In fact, I can do completion of the task in the course but not this anymore, Sandeep Bhai pls help...

I hope u can understand now. It's really very very difficult to invest resultless time into it. I'm not sure how you've thought to design this course which is that much cumbersome to candidates,,,, I'm not at all from IT background nor PRO like you,  but I've to be the one so pls help. Last update was in 2018 ,,, n we're practicing today ......

How to get the similar result like shown in the video, I'm facing file error, pls check and lemme know if I need to be in the same dir to call the file as similar to Unix/Linux or how to see and check the files which are existing in this module, etc, what's the concept behind it??? because without hands-on, the session n video is useless, pls reply asap, again I've wasted my 2 hrs in just a single small thing, why not u r making full-proof assistance to help candidates

Related to quoting the character,even this code is also working for me:

1. print("hello\ world")
o/p hello\ world

2. print("hello\\\* world")

o/p  hello\\* world

2nd one gives me two \\ which means that 1st '\' works to quote the character.
