Chapter 5 Case Study: Image Processing 151 pass Statement In Python, every function definition def statement, if statement, or for or while loop statement must have a body (i.e., a nonempty indented code block). A syntax error while parsing the program would occur if the code block is missing. In the rare occasion when the code in the blocks really doesn't have to do anything, we still have to put some code in it. For this reason Python provides the pass statement, which does nothing but is still a valid statement. In the next example we illustrate its usage, in a code fragment that prints the value of n only if the value of n is odd. if n % 2 == 0: pass # do nothing for even number n else: print(n) # print odd number n only If the value of n is even, the first code block is executed. The block is just a pass statement, which does nothing. The pass statement is used when the Python syntax requires code (bodies of functions and execution control statements). The pass statement is also useful when a code body has not yet been implemented. 10.3 (5 pts) The author says that The pass statement is also useful when a code body has not yet been implemented. Usually though, the presence of the pass statement is an indication that the code can be re-written to eliminate the empty block. Using the example in the book that illustrates the usage of the pass statement in a code fragment that prints the value of n only if the value of n is odd, rewrite the conditional statement so that the code does nothing for even number n without using the pass statement. (You should need only two lines of code.)
