There is a lot of examples of reading csv data using python, like this one:
import csv with open('some.csv', newline='') as f: reader = csv.reader(f) for row in reader: print(row) I only want to read one line of data and enter it into various variables. How do I do that? I've looked everywhere for a working example.
My code only retrieves the value for i, and none of the other values
reader = csv.reader(csvfile, delimiter=',', quotechar='"') for row in reader: i = int(row[0]) a1 = int(row[1]) b1 = int(row[2]) c1 = int(row[2]) x1 = int(row[2]) y1 = int(row[2]) z1 = int(row[2])

Step 1: In order to read rows in Python, First, we need to load the CSV file in one object. So to load the csv file into an object use open() method. Step 2: Create a reader object by passing the above-created file object to the reader function. Step 3: Use for loop on reader object to get each row.
Use pandas. read_csv() to read a specific column from a CSV file. To read a CSV file, call pd. read_csv(file_name, usecols=cols_list) with file_name as the name of the CSV file, delimiter as the delimiter, and cols_list as the list of specific columns to read from the CSV file.
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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
