Thank you! I had no idea CS50 Python did not consider a quote and a question mark as punctuation marks. I wish I had seen your video BEFORE wasting so much time going nowhere; the problem sets are not accurately worded. Very glad to donate, plus I have subscribed.

Thank you, that was very helpful in removing the frustration I was feeling not being able to resolve the numbers and punctuation errors.

[rongarza]

The problem description should state that CHECK50 doesn't consider a question mark and single and double quotes as punctuation marks. Your video saved me a lot of time and frustration. I have subscribed and donated using the Heart $ Thanks button above.

Thanks, after watching your video I realized that all I needed was
implementing a "test_number" function as well!

[orkhanmammadov]

I really appreciate the clear explanation in your video. It helped a lot.

[Landry_Houston]

After many hours. Here is my solution for people stuck. I do recommend trying to figure it out on your own...

def main():
message = input("Input: ")
msg_wo_vowels = shorten(message)
print("Output: " + msg_wo_vowels)


def shorten(word):
wo_vowels = ""
for letter in word:
if not letter.lower() in ["a", "e", "i", "o", "u"]:

wo_vowels += letter
return wo_vowels


if __name__ == "__main__":
main()

[angelicandoo]

We actually don't need to have a main() in the test_file, in the class they explain that when using pytest we just need to create the test_functions and assertions :)

[luanpires]

I was trying to use return inside the if condition inside the for loop, so it was just returning the first letter and breaking out of the loop.
To fix that, I used .replace inside def shorten(word) to replace every single vowel, although it worked, it looked a little bit ugly and repetitive.
Thanks for enlightening me.

[IgorVetkin-db]

def main():
user_input = input("Enter a text: ")
result = shorten(user_input)
print("Text without vowels:", result)



def shorten(text):
vowels = "aeiouAEIOU"
result = ''.join(char for char in text if char not in vowels)
return result



if __name__ == "__main__":
main()

[NomadLovesUs]

Personally don't think there's a need to create an empty variable and then add letters to it. You can simply use the replace() function to remove the vowels as I've shown below:

def main():
prompt = input('Input: ')
print(shorten(prompt))

def shorten(word):
for vowel in ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']:
word = word.replace(vowel, '')
return word

if __name__ == '__main__':
main()

thank you so much, explained the concept very well

[World_Tech_and_Cybersecurity]

weird question but how many files are supposed to be in submit50? 2? It says my /twttr.py will not be included? DO I need the for full credit?

[b.her_]

Thank you so much for the video, i just didn't understand why are we calling the test function in the test_twttr.py file . i mean there is no reason to call them since the pytest function could work without doing that with no issues.

icant import the shorten function its tells me ImportError

[Georgetvl]

My code:

tweet = input("Input: ")
print("Output: ", end="")
for letter in tweet:
if letter in ["A", "E", "I", "O", "U", "a", "e", "i", "o", "u"]:
continue
else:
print(letter, end="")
print()

[Upanya-Ch]

it says no tests ran oin 0.00 secs how do i fix it?

[federicoelevazo]

Hi Giovanna, I am getting an "Invalid slug" error during my check50. Any idea how to fix this? Thanks in advance

[roystn]

Can you help? I keep getting this: :( correct twttr.py passes all test_twttr checks
expected exit code 0, not 1

[mikebrignol]

she keeps saying it every time in the intro, yet a lot of people just come here to copy

[AK.]

my pytest was passing all the tests except the check50 one it kept saying that it expects exit code 0 not 1
