A machine cuts N pieces of a pipe. After each cut, each piece of pipe is weighed and its length is measured; these 2 values are then stored in a file called pipe.dat (first the weight and then the length on each line of the file)

 A machine cuts N pieces of a pipe. After each cut, each piece of 

pipe is weighed and its length is measured; these 2 values are then 

stored in a file called pipe.dat (first the weight and then the length on 

each line of the file). Ignoring units, the weight is supposed to be 

between 2.1 and 2.3, inclusive, and the length is supposed to be 

between 10.3 and 10.4, inclusive. The following is just the beginning 

of what will be a long script to work with these data. For now, the 

script will just count how many rejects there are. A reject is any piece 

of pipe that has an invalid weight and/or length. For a simple example,

if N is 3 (meaning three lines in the file) and the file stores:

2.14 10.30

2.32 10.36

2.20 10.35

there is only one reject, the second one, as it weighs too much. The 

script would print:

There were 1 rejects.
