watching this with the knowledge of loops is torture xD

[@sayanghosh6996]

@@rahulfederer20 because this is painful to look at when you already know all of this can be done in 2-3 lines using loops. not only is it small but also more soft-coded (as opposed to hard-coded) and considered a good programming practice. People who dont know programming already are not expected to know all this in week 1 or 2, so dont worry about it too much. once you learn it in future weeks, it would be clear.

[@hydrival]

Especially with a Java background lol XD

Ok Einstein, no need to make a fuss about that here

@@roshanekka9687 lol, there's nothing special about it, wait for 1 or 2 more weeks you'll learn that yourself. And stop taking everything as an attack lol chill.

Good class compared to the other sir

[@altairlight5729]

nice pedagogy

[@siddharthsoni1000]

better to use ord() , chr() functions

[@054_nirajkumar3]

@ 20:40 what was that error with Capital "I", why it need to change by small i???

[@abhishekkumarrai4975]

because 'I' is not present in alpha. String alpha is a collection of alphabets in small cases only.

[@rishabgangwar9901]

whenever I see joe I just say, "Hey, How you doin'?"

[@kmishy]

9:50 This can be also done like this
alpha='abcdefghijklmnopqrstuvwxyz'
name="manish"
nname=''
for i in name:
ind=alpha.index(i) +1
nname+=alpha[ind]
print(nname)

[@cookietree5625]

alpha = 'abcdefghijklmnopqrstuvwxyz'
name = input("Enter your name:")
new_name = ''
for i in name:
k = (alpha.index(i)+1)%26
new_name += alpha[k]
print(f"
{new_name}")
your code was breaking at "z" so i fixed it with some more additions like an input from user :)

[@tensorcodes]

But loops are not explained yet

[@nighteagle5529]

​@@cookietree5625why in print function the f exists. Plz reply

[@abhinavchaitanya5769]

​@@nighteagle5529Its a format specifier.

[@AK-ko3pw]

@@cookietree5625 alpha = "abcdefghijklmnopqrstuvwxyz"
name=input("Enter your name - ")
updated_name= ""

k = alpha[((alpha.index(name[i]))+1)%26]

print(updated_name)

[@ayushlabroo6238]

Why % 26 is added ?

[@raj_patel]

As per my understanding what if the name is "zoo".? we want ith+1 letter. So we want a z+1 letter. it's a. so 26%26 = 0 and we will get 'a'. (Maybe I am wrong, please correct me if I am)

you are absolutely right 👍

Is this included in week 1

[@avenumadhav3568]

This is from Week 2, precisely L2.7

[@minutecodingtips]

@@avenumadhav3568 sir are you a student of diploma or Degree or Foundation. I see you time stamped a lot of lectures from the different subject.
Thanks for helping us out🙏

Too much sound echo is there. Bad quality mic
