Loved the simplicity in teaching and also appreciate your effort to teach different methods associated with each one of the collections.

I am eagerly waiting for upcoming courses of Python with Selenium as there is much course on this topic

Hi Raghav, thanks for the videos.
I have a doubt with 'Remove' function. If there are duplicate values in the List, which value is removed first ?
If in case it removes which ever is first in the list(from below example 3 at index 1) then how to remove 3 at index 4 and index 7 without using remove function multiple times? Please help! Thank you in advance.
Ex: list=[1, 3, 4, 5, 3, 6, 7, 3]
list.remove(3)

Hi Raghav, I always follow your video when I need. I was looking for some automation in jira defect extract for multiple project but I could not find any related video here. Thought to ask you the queries if you can help
Currently in jql query I am passing as ( project in (x, y, z) and issue type = bug) and it give me the bug id for x, y, z project only. I want to read the project from Excel so that in future if any new project added I can just update the sheet not the script. Am trying for loop but am unable to use issetype=bug in the query. It is saying bug is not define. Can you guide me how I can achive it. Or if you have any link which I can refer pls suggest.

Thanks

class Myclass:
f_name = "Mitul"
l_name = 'Singh'

def __init__(self, fname, lname, age):
self.f_name = fname
self.l_name = lname
self.age = age


def sum(self, a, b):
print(a+b)


x = Myclass("Shivanshi", 'Sharma', 6)
print(x.f_name)
x.f_name = 'Lipika'
print(x.f_name)
#del x
del x.f_name
print(x.f_name)
x.sum(7, 7)

Print(x.f_name) after del.x.fname is printing "Mitul" no error is coming.


Shivanshi
Lipika
