Exercise 1
What is output by the following code sections?
for i in range( 5 ): for j in range( 3 ): print i+j, print
for i in range( 3 ): print '-' * i
for i in range( 4 ): for j in range( i ): print j * '-'
Exercise 2
Write the code necessary to take the string "jan31feb28mar31apr30" and generate the following output from it:
jan 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30 31 feb 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 mar 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30 31 apr 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30
Exercise 3
Use this Python Quick Refence guide for this Exercise.
Given the list of string poem shown below, generate the code that prints it as shown.
poem = [ "If the person you are talking to", "doesn't appear to be listening," , \ "be patient. ", "It may simply be that he has", "a small piece of fluff in his ear." ]
If the person you are talking to Doesn't appear to be listening, Be patient. It may simply be that he has A small piece of fluff in his ear.
