Python email slicer exercise 📧

[@BroCodez]

email = input("Enter your email: ") username = email[:email.index("@")] domain = email[email.index("@") + 1:] print(f"Your username is {username} and domain is {domain}")

[@omgitsmcj3420]

Thank you

[@beepbeepgamer1305]

i prefer partition over index slicing but for the given logic is useful tho.

[@qaisherzallah]

It is a perfect and superuseful excersise but what you did at the last by typing email.index("@") twice is a bad practice btw cuz u are calling the same fuction twice , and this is a bit hard to the memory

[@Computer-v5e]

Thank you master bro

[@dragomirpetrov5138]

You really make coding look easy. This is coming from a guy who just finished your C course :D

[@migukau]

Its important to note that the second method is less efficient because you are calling the index function twice instead of just calling it once.

I just watched after coming back from the the college. You makes the so beautiful. I hope to master python just after m done with JavaScript. Your JavaScript lesson are also the most beautiful part. I love it brother. Thank you!

[@harunisiaho]

Thank you. Very helpful We can also use str.split function as below email = input('Enter your email address: ') username, domain = email.split('@') print(f'Your username: {username} and domain: {domain}')

[@Camaron242]

That’s what I thought would’ve been the most straightforward method

[@beepbeepgamer1305]

Just use the in-built python fuction which is called as ".partition()". What this basically does it, you specify the string object lets say x="This line of code will partition the word banana into 3 different words in a list". Then give another listobject lets say "a". There the code would go like this. >>> a=x.partition("banana") >>>print(a) ["This line of code will partition the word","banana","into 3 different words in a list"] This is very useful for real life applications such as machine learning, keyword identifying, spelling mistake checking and alot more. The return type of this partition is a list of strings where the strings before the word "banana" is a part of string followed by the partitioned word "banana" and then the rest of the string after banana into a sperate one. The length of the separation is always 3 as words before the given word and then word itself and the words after the give word. Partition only works for string datatype and nothing else. So don't forget to give the given word inside in quotes, you could also store the string in a separate object and specify it in inside the parenthesis without the quotes. Hope this gave an alternate method for the same solutions, stay programming always 😎😎

Love you man!!!! You inspire us all!!!!

[@kashmirtechtv2948]

you are amaizng

[@kapibara2440]

Great video ❤

[@dharmawangsa9592]

I understand java and data structure after watching your vids. Man you are legend. Can you crate tutorial about spring boot and rest api I know you are good at java

[@vkamalesh9387]

thank you bro

[@fabienekoutesone6046]

Thank u Bro

[@gian-mm9kr]

Hey, could you explain to me the difference between the .index and the .find ?

[@h4560]

the difference is that .index will have an error when it’s not able to find what it’s looking for and .find returns a -1 if not able to find what it’s looking for. Other than that they do the same thing where they return the lowest number where the character is found.

[@jomon-bq8hz]

@@h4560 thank you 💡💡

[@Lit35]

took me a while to figure this out

[@brunogreco290]

Hello. Please make a full course on Springboot framework. Microservices Docker.

[@fabulous6202]

we can also use 'find' method instead of 'index'

[@alexandertorres9028]

Hi bro code could you make a SQL video please have a nice day ;)

[@toxicrootvip7264]

Thanks Legend

[@fmmaks]

Why not str.split()?

[@omairtech6711]

LOL I was thinking the same.

[@danielhod53]

what microphone and keyboard you use?

[@jeiddoromal4804]

I just wanna ask what's the purpose or function of +1 ?

[@ClashForTheWin]

so that the @ itself shouldn't be printed because when printing domain the @ becomes inclusive

[@charitoskalikatzarakis8510]

Less lines of code makes the program runs faster?

[@ClashForTheWin]

does it?

[@J2128H]

just to add to your already excelent content, if i may: you can also achive the same in the follwoing way: email = input("enter your email: ") user_name, domain_name = email.split("@") print(f"your username is {user_name} and your domain name is {domain_name}.") * this only works if you know ahead of time that you're going to recieve two strings after the split.

[@nightwish2803]

Hello bro! I'm a beginner programmer and just started learning java a month ago. I'm not very good at it and I want to improve. I have bad logic and always cant think the other way around and stuck on a method. Is there anyway for me to improve?

python, gangsta language LOL

[@Gooseknuckle]

Bro, do you have a discord server?

[@kulanimanganye]

Hey, where can I practice this ? On github or ?

[@ehraz786]

Can remove 2 more lines if you want 😂

[@chip0k]

my solution: username, domain = email.split('@')

[@arshiaa104]

Comment

[@avivsmadja9159]

email = input("Enter your email: ") print(f"Your username is {email[:email.index("@")]} and domain is {email[email.index("@") + 1:]}") less lines of Code

[@shakil1766]

f-string: unmatched

[@MAT.H404]

email = input("Enter your email: ") name = email email = email.find("@") name = name[email+1:] print(name)

[@ananyahc8589]

email.find("@") does the same job as email.index("@")
