Hi all,

I seem to be having problems with summing all the values in a .csv file with the following format:

```
3.2323232312
7.5345345675
3.3423565624
etc...
```

I have opened this with a spreadsheet at it seems the floats are all in column[0] and each number is on a different row.

```
with open("E1.csv", "rb") as ins:
for row in csv.reader(ins):
print sum(map(int, row))
```

This gives the following error:

ValueError: invalid literal for int() with base 10: "0.2035..."

I would really appreciate some help, thanks.
