Check if CSV file is empty or not after reading with DictReader

Question

I'm opening a CSV file and I need to check if the file empty or not, I already know about checking using getsize(). I would like a way by using DictReader. This is my code

infocsv = open('nyfile.csv', 'a')
reader = csv.DictReader(infocsv)

Answer 1

 with open(parafile, "rb") as paracsv: #Read in parameter values as a dictionary paradict = csv.DictReader(paracsv) has_rows = False for line in paradict: has_rows = True if not has_rows: return None 

The number of lines read from the source iterator. This is not the same as the number of records returned, as records can span multiple lines.

Answer 2

Here is an alternative solution:

import csv
with open('nyfile.csv') as infocsv:
    reader = [i for i in csv.DictReader(infocsv)]
    if len(reader)>0:
        print ('not empty')
    else:
        print ('empty')

I tried it on a few CSV files of my own and it works. Let me know if this helps.
