QUESTION
I've written this offline dictionary program. I want when the user presses a key, this program to go into the database and find a word close to the word entered by the user so far. Or when the user entered a word completely and the word was in the database, the program would display it with its meanings.
For this part everything is going well. Then I want for example when the user entered the word "a", program shows all words in database that starting with "a".
Here is an example of my problem: When we enter "a" all words and meanings that begin with "a" should be displayed. But the program shows something like this:
And here is some of my database with json format:

Answered 2020-Feb-28 at 16:09If someone enters a, you're calling getMeaning which in turn calls get_close_matches. You're then checking if that call has a non-zero-length return value and if it does you do return DataBase[close_match]. That's where getMeaning ends.
You'll never reach the else-part of getMeaning, if get_close_matches produces results. In the screenshot of your question, we can see the results of user input a which make sense like this since get_close_matches finds cat is similar to a.
Disregarding that, you should use startswith if you want to test if a string begins with another string. Also, you don't need elif or else after the previous if or elif has a return and I have changed the names according to PEP 8 section Descriptive Naming Styles.
Here is a possible solution, using a filter which only accepts a close match if the letters are the same as in word:
QUESTION
I am trying to check if each character in my string is capitalized. I have to use a loop, and cannot use regex. My idea is that the loop checks each character whether or not it is both capitalized and a known character. If it gets to a character that is not both capitalized and known, it exits the loop and returns false, otherwise it returns true.
...ANSWER
Answered 2019-Oct-20 at 01:48This is because as soon as a function returns a value, it ends and does not continue. Thus, as soon as it reaches a capitalised character (if is_capitalized(char)), it will return True and not check the rest of the characters.
You can take advantage of this and immediately return False once you see an invalid character, and if the for-loop reaches the end, then you know that all your characters must be valid (capitalised):
QUESTION
I'm trying to parse a source from a other webspace. The problem is that the other webspace loads the news with javascript. And every code here on Stackoverflow or Google parse the source before the news is loadet
I know it doesn't work with php therefore I tryed it with jquery, without success.
...ANSWER
Answered 2019-Jun-04 at 19:55It seems impossible to do kind of page content scraping on client browser. You have options which may be chosen to do at the server side. Scraping a heavy javascript web page often needs our app (in this case at server side) to control a browser to render complete page firstly by waiting for a timeout duration, then read the rendered content for parsing necessary information.
- If you prefer PHP, Selenium with its PHP's driver may be an option.
- Or if you prefer Javascript on NodeJS, lot of options but this article may be a good reference for you. Where they guide to use puppeteer (to control browser for rending complete page) and cheerio (to parse the page content with ease) for solution.
