Question

1. Write the outputs of the following loops
2. a.   for count In range(5):

         print count + 1

    b.  for count in range(1,4):

         print count

     c.  for count in range(1,6,2):

          print count

      d. for count in range(6,1,-1):

          print count

1. Write a loop that prints your name 100 times. Each output should begin

   on a new line.

 3. Explain the role of the variable in the header of a for loop.

1. Write a loop that prints the first 128 ASCII values followed by the

   corresponding characters (see the section on characters in Chapter 2).

1. Assume that the variable testString returns to a string. Write a loop

   that prints each character in this string, followed by its ASCII value.

Answer 1

a) There are syntax and compile errors...

In must be lowercase, parenthesis are required

for print statements

The correct statement for this for loop is:

for count In range(5):

print count + 1

Once corrected the output is:

1

2

3

4

5

b) Again, there is a compiler error because parenthesis

are required for print statement.

The correct statement for this for loop is:

for count in range(1,4):

print count

c) Same error, print statement requires parenthesis....

The corrected for loop is:

for count in range(1,6,2):

print(count)

The output is:

1

3

5

d) Same error, print statement requires parenthesis...

THe corrected for loop is :

for count in range(6,1,-1):

print (count)

The output is:

6

5

4

3

2

#Prints your name 100 times

for count in range(100):

print ("Your name")

#Displays ASCII Table

print(" -----------------------------------")

print(" the 1st 128 ascii values...........")

print(" ascii value character ")

for asciiLoop in range(128):

print(" " +str(asciiLoop) + " " + chr(asciiLoop) )

print(" -----------------------------------")

print(" the 1st 128 ascii values...........")

for asciiLoop in range(256):

print( " " + str(asciiLoop) + " " + chr(asciiLoop) )
