How to build an isogram checker in python

Question

I am trying to build an isogram checker where each letter present is used the same number of times. I have viewed codes and discussion referencing this but they only check if the letters have only been used once. They don't check if the for the word maybe has letters which all appear twice like 'deed'.

Answer 1

I can explain the code, but lecturers haven't covered the part on imports yet, so I don't know if I can use.

I managed to make it without import, thanks so much for the help :)

This is what I have now, I got to work by importing counter but I don't wanna use import. My lecturer might not allow that.

Ipang I am might not be allow use import

Answer 6

Even if you can explain your code to the lecturer? I understand if a student can't explain what they use, but shouldn't it be okay otherwise?

Answer 8

Ipang it doesn't check if the word has each letter appearing the same times other than once. So a word like 'peep' will where each letter appears the same number of time but instead twice the functions used above return false even though it is an isogram.

Answer 10

Isn't that code working as you expected? what is the problem?

Answer 11

Lothar thanks so much for the help! Work like a charm really appreciate it!

Answer 12

And what was your doubt?
Isn't it the requirement? to confirm when the string contains unique letters only?

What was the problem with "check if the letter have only been used once."?

Answer 13

Uses `set` and comprehension
