Assume I have a csv.DictReader object and I want to write it out as a CSV file. How can I do this?
I know that I can write the rows of data like this:
dr = csv.DictReader(open(f), delimiter=" ")
# process my dr object
# ...
# write out object
output = csv.DictWriter(open(f2, "w"), delimiter=" ")
for item in dr:
output.writerow(item)
But how can I include the fieldnames?

How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
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

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