Define a function below, filter_out_strs, which takes a single argument of type list. Complete the function so that it returns a

list that contains only the non-strings from the original list. It is acceptable to return an empty list if there are only strings in the original list. This question uses the filter pattern discussed in lecture.

Answer:

Explanation:

The following code is written in Python and is a simple function that removes all of the type String elements within the list that has been passed as an argument. Then finally, prints out the list and returns it to the user.

def filter_out_str(list):

   for x in list:

       if type(x) == type(" "):

           list.remove(x)

   print(list)

   return list

Assume that name is a variable of type String that has been assigned a value. Write an expression whose value is the first chara
andrezito [222]

Answer:

name.charAt(0);

Explanation:

Given: 'name' is a variable of type String that has been assigned a value.

To determine: an expression whose value is the first character of the value of name.

Let us assume nae is assigned the value "test". So our expression should return the first character , that is 't'.

In order to do this, we can use the charAt method of String object.

String name="test";

char c = name.charAt(0);

Here 0 corresponds to the index of the character we are interested in.
