Hello, I got a csv file, in which I have to count the occurrences of certain numbers in columns. I can do this for one arbitrary column, but not for all.
The problem I encountered is as follows. Iterating through the rows of a
file works, but as soon as I try to iterate through the same file again,
it seems it returns nothing.
Code-example
------------
import csv
file = csv.reader(open("some.csv", "rb"))
for i in file:
print i
for i in file:
print i
some.csv:
3, 4, 5
4, 3, 2
The above program only returns:
['3', ' 4', ' 5']
['4', ' 3', ' 2']
instead of:
['3', ' 4', ' 5']
['4', ' 3', ' 2']
['3', ' 4', ' 5']
['4', ' 3', ' 2']
Any help would be welcome.
