The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.

Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.

However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.

How does abstraction help us write programs
Misha Larkins [42]

Answer:

Abstraction refines concepts to their core values, stripping away ideas to the fundamentals of the abstract idea. It leaves the common details of an idea. Abstractions make it easier to understand code because it concentrates on core features/actions and not on the small details.

This is only to be used for studying purposes.

Hope it helps!

Give a pseudo-code description of the O(n)-time algorithm for computing the power function p(x,n).Also draw the trace of computi
laila [671]

Answer:

p(x,n)

1. if(n==0)    [if power is 0]

2.    then result =1.

3.else

4. {    result=1.

5.      for i=1 to n.

6.          {  result = result * x. }  [each time we multiply x once]

7.       return result.

8.  }

Let's count p(3,3)

3\neq0, so come to else part.

i=1: result = result *3 = 3

i=2: result = result *3 = 9

i=2: result = result *3 = 27

Explanation:

here the for loop at step 4 takes O(n) time and other steps take constant time. So overall time complexity = O(n)
