Histogram exercise

gistfile1.txt

Build a command line tool which takes a CSV file-like input, and creates an histogram in ASCII

data = [(0,1),
        (2, 4),
        (4, 2),
        (3, 3)]


Each row in the CSV is data which helps build the histogram. The first value is the column #, the second value is the value of bar in the histogram.

There can be more than one row for one column in the CSV


mehdi$ python histogram.py

01234<- no need to print this, but this is just to explain the columns

#for column 0, there is 1 star, which represent the value of (0,1) in the data list.
#for column 1, there are 0 stars, because there is no tupe (1,)
#for column 2, there are 4 stars, because there is (4,2) in the data list
#for column 3, there are 3 stars, because there is (3,3) in the data list
#for column 4, there are 2 stars, because there is (4,2) in the data list
