Lorico [155]

Answer:

def remove_duplicates(lst):

   no_duplicate = []

   dup = []

   for x in lst:

       if x not in no_duplicate:

           no_duplicate.append(x)

       else:

           dup.append(x)

   for y in dup:

       if y in no_duplicate:

           no_duplicate.remove(y)

   return no_duplicate

Explanation:

Create a function called remove_duplicates that takes one parameter, lst

Create two lists one for no duplicate elements and one for duplicate elements

Create for loop that iterates through the lst. If an element is reached for first time, put it to the no_duplicate. If it is reached more than once, put it to the dup.

When the first loop is done, create another for loop that iterates through the dup. If one element in no_duplicate is in the dup, that means it is a duplicate, remove that element from the no_duplicate.

When the second loop is done, return the no_duplicate

Provide an example of making multiple paragraphs tags using html and at least 3 sentences.
DiKsa [7]

Answer:

<p> tag:

The <p> tag in HTML defines a paragraph. These have both opening and closing tag. So anything mentioned within <p> and </p> is treated as a paragraph. Most browsers read a line as a paragraph even if we don’t use the closing tag i.e, </p>, but this may raise unexpected results. So, it is both a good convention and we must use the closing tag.

Syntax:

<p> Content </p>  

Example:

<!DOCTYPE html>  

<html>  

<head>  

   <title>Paragraph</title>  

</head>  

<body>  

   <p>A Computer Science portal for geeks.</p>  

   <p>It contains well written, well thought articles.</p>  

</body>  

</html>

Output:

A computer Science Portal for geeks.

It contains well written, well thought articles.
