How to read one single line of csv data in Python?


To read only the first row of the csv file use next() on the reader object.

with open('some.csv', newline='') as f:  reader = csv.reader(f)  row1 = next(reader)  # gets the first line  # now do something here   # if first row is the header, then you can do one more next() to get the next row:  # row2 = next(f)

or :

with open('some.csv', newline='') as f:  reader = csv.reader(f)  for row in reader:    # do something here with `row`    break


you could get just the first row like:

with open('some.csv', newline='') as f:  csv_reader = csv.reader(f)  csv_headings = next(csv_reader)  first_line = next(csv_reader)


You can use Pandas library to read the first few lines from the huge dataset.

import pandas as pddata = pd.read_csv("names.csv", nrows=1)

You can mention the number of lines to be read in the nrows parameter.
