Differences between revisions 4 and 8 (spanning 4 versions)

Practical 1

Before staring with the exercises, have a look at the python tutorial, here.

(a) Start a ScrumPy session, and make the following assignments:

   1 >>> num_type_1 = 8
   2 >>> num_type_2 = 9.0
   3 >>> str_type = 'a'

What do you think the value and type of the following expressions are?

num_type_1/2
num_type_1/2.0
num_type_2/3
5 + 2*10
str_type*4

Control your answers using Python. Any deviations from expected? Why?

(b) Create a list with six items, e.g.:

   1 >>> test_list= ['a', 'b', 'c', 'd', 'e', 'f']

Make another list (reversed_list) that is a copy of the first, e.g.:

   1 >>> reversed_list=test_list[:]

(why will this assignment result in a copy of test_list? Hint: this is a slicing operation.)

Now, reverse the order of the items in reversed_list by repeating the following assignment with suitable choice of n and m:

   1 >>> reversed_list[n]=test_list[m]

(c)
