First we need to understand what "n for n in range(10)" means. Basically, we are iterating through all the values n that are in the range of 10 (meaning 0, 1, 2, 3, ..., 9).
Next we are evaluating if n%2. The percentage sign is used to represent modulus which is the remainder of when two numbers are divided. In this case, we are dividing n by 2, and the remainder is our result. When dividing by 2, the only possible remainders are 0 or 1, which when used in an if statement represent the boolean vlaues false and true, respectively. We are doing this calculation for each n from 0 to 9, and if the result is true, we output n to an array.
The numbers that will result in true (a remainder of 1) are the odds numbers. For example, 4/2 = 2 with nothing left over while 5/2 = 2 with 1 left over.
<span>Pinhole cameras were one of the most sophisticated devices of the period, it made tasks much easier it basically worked exactly like the human eye and is something just like tracing.
