how to get the size of csv file line by line?is thas possible using python-CodePudding

I am reading a csv file without pandas library,i need to find out the number of bytes of each row.So i can ad all the bytes and determine the file size and will do some restriction based on that.

file="Emptycsv.csv"
checkfilesize(file)

def checkfilesize(file):
 file=b''join(file).split(b'\n')
 count=len(file)

Count will print the number of rows.i need to find out the file size,i know os.path.getsize will do..But while reading that csv file row by rows/column or columns if it reached 109997897kb,i need to terminate.So request you to help me the find the bytes of data

CodePudding user response：

Something along the lines of this should work for getting the bytes per row/line:
(The 1 is for the newline)

import os

total_bytes = -1

with open("test.csv") as file_in:
    for line in file_in:
        bytes_on_this_line = len(line)   1
        total_bytes  = bytes_on_this_line
        
print(total_bytes)

print(os.path.getsize("test.csv"))

Output:

15
