Exercises on Statements and Expressions

The Think Python author has given 2 more sample problems in order to understand the various statement and expression behaviours.

Assume that we execute the following assignment statements:

width = 17

height = 12.0

delimiter = '.'

For each of the following expressions, write the value of the expression and the type (of the value of the expression).

1. width/2
2. width/2.0
3. height/3
4. 1 + 2 * 5
5. delimiter * 5

Use the Python interpreter to check your answers.

I’m trying to guess the answers first.

           1.      8

           2.     8.5

           3.     4.0

           4.     11

           5.     …..

Now I’m trying the same using interactive mode and the snapshot is given below.

Next problem is

Practice using the Python interpreter as a calculator:

The volume of a sphere with radius r is 4/3 π r³. What is the volume of a sphere with radius 5? Hint: 392.6 is wrong!

We should carefully use the integers and floating point values in division.
