According to PEP 8 it's important to skip 2 lines after function block. Just for beginners to pay attention on that

Loving your simplicity and evenly broken module.Would it be possible for you to make a video series with Project like Data Science.Thank you

[avisheksaha]

Extremely glad to watch all your videos regarding python and data science. You explained it not only quiet well but extremely well. Thank you. Looking forward to watch all your upcoming lessons.

[RM-lbxw]

Loving this series. Any chance you are going to make a series on Data Structures and Algos in the future? Would really love to learn from you.

[mousumimaity]

A helpful video to make clarity on if condition, for loop etc.

[shwetaredkar]

You should be in teaching field not in industry. Academics need people like you for good understanding of programming.

[bhanuprathapnaidu]

Really clear explanation sir, Great work. Thank you so much

[prakharmishra]

you are really great sir, i respect your altruistic work

[shubhacshekar]

Great hard work really appreciate your simplicity in explaining beginners.Thanks sir.

In your exercise solution for printing stars, two loops are used . I used the below code to get the same solution. Can i have your comment on this, please
def printStars(endNumber) :
total = ""
for i in range(1, endNumber+1) :
total += "*"
print(total)
printStars(5)

[MrShinshan]

in the solution for print * can we not use just one for loop like below
def print_pattern(num):
n = range(num+1)
for value in n:
print (value * "*")

pulp = print_pattern(3)
print(pulp)

[pushpayerraguntla]

This is awesome code man, thanks a lot. God bless you

[devloper_hs]

Sir why haven't you included **ke for giving multiple arguments in a fn

[Studentof]

Why do we need 2nd loop to print stars when we can do it with just a single main for loop?

[anuruddhtamrakar]

while using default argument letting b=0 if we give variables as user input and then it shows error sir. How can we overcome it?

[TonydeSa]

You've mentioned that you have posted exercises after each video. Can't seem to find them. Can you please post a link to the exercises? Your tutorials are great and working on exercises after them would help to fix them.

[Griffindor]

Excellent video!
There's an exercise? I can't find it here.

[fitarmy]

I want to learn machine learning and AI will this course be effective to my path?

[farahamirah]

Im sorry sir., Its difficult to understand the exercise., I try to make it by myself without looking solution, for example, the exercise say, input value., So I try to make user put an input., then i got blur, i go to the solution, the input is already given.

[thulasiram]

Anyone Please explain that line total = total + item icant understand
