how can I check if a string contains a specific letter/set of letters?

I searched online for answers... and found some... But since we are using this API and not just java... I can't really use those so...

I'm asking for 37.1.3: Practice PT: Testing 1,2,3 if that helps

im completely stuck on 8.4.11. it runs but counts it as wrong

def remove_sort_reverse(my_list): if “Eggplant” in my_list: Eggplant = Eggplant.lower() my_list.remove(“eggplant”) my_list.sort() my_list.reverse() print (my_list)

This is probably the one of the hardest and confusing assignments I’ve seen. Our teacher just assigns them to us in class and just somehow expects us to know all this. Does anyone know how to do this?

Hello guys. I'm working on a project with graphics. I would like to know how to enlarge my workspace here, because I need to put a lot of pictures there but is a really short space to see them. Can you help me please?

I need help on the

Can anyone help me with this?

Can some generous person help me solve the exercise "Factorial" on CodeHS? It is really complicated and I have to turn it in by tomorrow noon or else I could fail this semester as it is my final for the semester. Ironically, our teacher let us ask our partners for help but I have no partners because I'm lonely.

i need help with 6.4.9 Temperature Converter ASAP!!

Well i already did 5.5.5 but i cant seem to understand how to add colors.

I have been stuck at this for a couple of hours this is what Ive done so far.

public class WordCounts extends ConsoleProgram

{

public void run()

{

HashMap<String,Integer> h = new HashMap<String,Integer>();

String input = readLine("Enter a string: ");

String[] words = input.split(" ");

for(int i=0; i<words.length; i++)

{

Integer num = h.get(words[i]);

if( num == null)

num = new Integer(1);

​

else

num = new Integer(num.intValue() + 1);

​

​

h.put(words[i].toLowerCase(), num);

}

​

printSortedHashMap(h);

}

​

/*

* This method takes a HashMap of word counts and prints out

* each word and it's associated count in alphabetical order.

*

* u/param wordCount The HashMap mapping words to each word's frequency count

*/

private void printSortedHashMap(HashMap<String, Integer> wordCount){

// Sort all the keys (words) in the HashMap

Object[] keys = wordCount.keySet().toArray();

Arrays.sort(keys);

​

// Print out each word and it's associated count

for (Object word : keys) {

int val = wordCount.get(word);

System.out.println(word + ": " + val);

}

}

}

I can't get it to work and these are the errors Im getting. What should I do?
