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

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])

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

Answer #1

os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.
