i was stuck searching in docs for soo long, tysm

[moeletsimelamu]

I’m low-key mad at myself because I’ve been reading the docs, and I thought of the replace but I just wasn’t sure 😭😅thank you so much

[FahimIstihadAnik]

Despite having low audience i love how much effort you put into your channel i wish you grow more and reach out to more people like me. Making people learning much smoother.

[programram-hght]

thank you. i had used the replace method too

[notwenli]

Another solution to this problem could be

msg = input(" ")

print(msg.replace(" ", "..."))

Giovanna I would like to thank you for this tutorial, I was struggling during a week to know how to send a validation code, I hope some day to be in your group

This is interesting. I had a completely different approach.. That's what I love about programming. So many different ways to solve the same problem. I used split and join as follows:

text = input()
words = text.split()
result ='...'.join(words)
print (result)

[sakshamgarv]

I didn't know about replace function while solving had to search it up

[sakshamgarv]

Thanks! I was stuck, I finished but It took a lot of time to solve for me

[wsptxtd]

My solution is #define main function
def main():
#assign a variable named slowdown with input for user prompt
slowdown = input("")
#split slowdown into each word
eachword = slowdown.split()
#join each word with ... sep
word = "...".join(eachword)
print(word)
main()
Mine has more line of codes which I've learnt has more probability for errors. Do you think my solution will be useful in a different situation or more complex programs? I feel more comfortable to define a fucntion because I believe I can call it whenever I want again. I'd like to read your guidelines and sugguestions pls seniors.

[FallenAngelMMA]

Thanks a lot! How do we do the check50 ? Mine asks for a security key or something -__-

[fatjawns]

I made one but mine only had the "..." at the end of the sentence. I had no idea what function would work and sorry im not going through the monstrosity that is the python doc to find something I would still be confused on using. Thanks!

Please learn the rest of the problem sets, I learn very well with you, please post the rest of your Python problem sets❤️🥲

Hello, thank you so much for the videos, going to start college at IMC in austria and also having my own solution to this pset:

user_input = input("Write something here: ")

x = user_input.split(" ")

for word in x:
if word == x[-1]:
print(word)
break
print(word, end="...")




also working fine :)

[heliamousavi]

How can i do it by myself
I watched my courses video and i still don’t know how to write a code or pass my problem set without help?

[zobaonwuli]

Can you also use sep='...' instead of the replace function? If so, how would that look?

[sahilsvision]

message = input()

print(message.replace(" ", "..."))


also works

[mohamedalaafahim]

i came from cs50, and i didn't solve this problem set with replace function because i didn't know it
so i solved it with that

massage = input("").split(" ")

last = massage[-1]
massage.pop(-1)

for i in massage :
print(i, end="...")

print(last)



it worked i wonder if it was good or what

[johnbackman]

Did similar using replace but did it with a function

def dotted_lines():
print(input().replace(" ", "..."))



dotted_lines()

[mariamgalal]

Why we can not use split method and put the prameter(...)
