1.3.6 Tuples and Lists

Conclusion

1. Consider a string, tuple, and list of characters.

In []: a = 'acbde'

In []: b = ('a', 'b', 'c', 'd', 'e')

In []: c = ['a', 'b', 'c', 'd', 'e']

The values of a[3], b[3], and c[3] are all the same. In what ways are a, b, and c different?

a is a string, b is a tuple, and c is a list.

2. Why do computer programming languages almost always have a variety of variable types?
Not everything can be answered with one variable type. For example, some situations require a true

or false statement whereas others require a number. These varibales would have to be two different types.

3. Why can't everything be represented with an integer?

Not all situations require an integer. Some require a true or false. Others require a float in that the decimal places need to be accounted for.
