3.3. Some Examples

Some examples of variables and datatypes:

3.3.1. Average of N numbers

In the next program we will do an average of N numbers.

#!/usr/bin/env python
N = 10
sum = 0
count = 0
while count < N:
    number = float(raw_input(""))
    sum = sum + number
    count = count + 1
average = float(sum)/N
print "N = %d , Sum = %f" % (N, sum)
print "Average = %f" % average

The output

$ ./averagen.py

N = 10 , Sum = 38.800000
Average = 3.880000
