Fix Python – How to obtain the total numbers of rows from a CSV file in Python?

Question 1

I’m using python (Django Framework) to read a CSV file. I pull just 2 lines out of this CSV as you can see. What I have been trying to do is store in a variable the total number of rows the CSV also.

How can I get the total number of rows?

file = object.myfilePath
fileObject = csv.reader(file)
for i in range(2):
    data.append(fileObject.next())

I have tried:

len(fileObject)
fileObject.length

Question 2

You need to count the number of rows:

row_count = sum(1 for row in fileObject)  # fileObject is your csv.reader

Using sum() with a generator expression makes for an efficient counter, avoiding storing the whole file in memory.

If you already read 2 rows to start with, then you need to add those 2 rows to your total; rows that have already been read are not being counted.
