- Take input from user by using ``raw\_input()''.
- Display a prompt to the user before taking the input by passing
a string as an argument to ``raw\_input''.
* Evaluation
1. ``a = raw\_input()'' and user enters ``2.5''.
What is the type of a?
- str
- int
- float
- char
2. ``a = 2'' and ``b = 4.5''.
What does print "a is %d and b is %2.1f" %(b, a) print?
- a is 2 and b is 4.5
- a is 4 and b is 2
- a is 4 and b is 2.0
- a is 4.5 and b is 2
* Solutions
