~~inporting ~~import csv ~~file however ~~file: integers appearing as floating points

~~Hi I'm ~~Hi,

I am trying to import a csv file in order to create an adjacency matrix ~~to ~~and then plot ~~a ~~the associated directed graph. ~~ I've uploaded ~~I upload the csv file and ~~then used this code ~~use its content to generate ~~the ~~a matrix as follows

```
sage: import csv
sage: data = list(csv.reader(file(DATA+'matrix23.csv')))
sage: m = matrix([[ float(_) for _ in line] for line in data])
sage: m
```

~~However although ~~Whereas my csv file only contains integers 1's and ~~0's. ~~0's, the generated matrix is floating point 1.0's and ~~0.0's. This then causes problems trying to create ~~0.0's!

Note: the ~~graph. The ~~CSV file was created using MS Excel with cells formated to zero decimal places. ~~ ~~

I'm new to both python and sage and can't find anything on the forums to help
