I tried to learn "Data Analysis with Python" course. Completed week 1 course. But can not perform Lab. Please help. I want to register for Python and R in course era. But with out performing lab, it is of no use.

Need live chat, support for Lab sessions. I have subscribed "Data analysis with python"", but unable to start Lab. a week gone after subscribing. No use. feeling worst

In the final question on functions, you say 'concentrate' when you intend 'concatenate'.

In box [13] you define a Rating variable that you don't need. A simpler solution is

PlayListRatings = [10, 9.5, 10, 8, 7.5, 5, 10, 10]
i = 0
while PlayListRatings[i] >= 6:

print(PlayListRatings[i])

i = i + 1

if(i > 1000):

    break

Note this example includes a safety mechanism that avoids infinite looping. I would never teach the while loop without warning students about the dangers of infinite looping. . . .

The question says, 'Write a for loop the prints out all the element between -5 and 5 using the range function.' You should specify whether the between includes or excludes the lower and upper bounds. English does not have separate words for each of the four possible cases, so using one word for all four cases creates ambiguity that leads to four possible correct answers.

The instruction refers to the "range object." Why not just say (more precisely) that the range type amounts to an (ordered) sequence of integers, and the range() function generates such sequences? This is computer programming. We can be fully exact from the git go. We don't have to gloss or approximate these little truths for the sake of simplification or summarization.

The question asks to print the year the album came out. The sample code prints 'This album came out already'. You should make them consistent.

Your instructional text says string comparison is according to ASCII collation order. The Python 3 documentation says, "Strings (instances of str) compare lexicographically using the numerical Unicode code points (the result of the built-in function ord()) of their characters." So your statement is only true for ASCII characters. Why not tell the whole truth?

The sample code creates the variable 'intersection' as a token representing the result of an intersection operation. Inasmuch as the same term is the name of a method defined by the language, it's bad form to use the reserved term as a variable name. I suggest you change it to e.g. 'my_intersection'.

Add instruction for index() function before the quiz on tuples asks the learner to demonstrate its use.

Jupyter has a bug that causes the cell editor code to be cutoff at the bottom when you switch on and off the Dark Reader extension in Chrome.

hi please add a thing to install dependencies like
zlib1g-dev
with
apt-get install zlib1g-dev command

In the juypter notebook for polynomial regression, r2_score() is used incorrectly - true and predicted values are interchanged. Therefore, the values differ from the results provided by .score() from LinearRegression()

The Jupyter lab is not working and is feeling difficult to learn without it

server connections failed in jupyterlab

Hello,

The image below has a slight mistake. Negative index [-2] should be 10.1

hi
just to let you know that there is mistake in the "Lab-Conditions and Branches.
the variable is an integer type and the one given in the condition statement is of string type.
