Python has a csv module for reading and writing CSV files (usually exported by Excel or database tables). The basic use of this module is documented in the on-line help. My CSV files usually have a header row, so the idiomatic way to skip this line is to open the CSV file and use the next() function immediately:
from csv import reader f = open("blah.csv", "rb") f.next() for row in reader(f): print row
If your CSV files are pretty simple (e.g. only single line data, no quotes, etc.), you can use list comprehension and array slicing:
1 2 3 for row in [line.strip().split(',') for line in file("blah.csv")][1:]: print row
- You have to remove the trailing "\n" from each line.
- Split the input line using the delimiter, typically a comma.
- The list comprehension statement returns all lines, so to ignore the first line, you take a slice of the array starting from the second line.
