I am a newbie at Python & I have a web scraper program that retrieved links and puts them into a .csv file. I need to add a new line after each web link in the output but I do not know how to use the \n properly. Here is my code:
file = open('C:\Python34\census_links.csv', 'a')
file.write(str(census_links))
file.write('\n')
Hard to answer your question without knowing the format of the variable census_links.
But presuming it is a list that contains multiple links composed of strings, you would want to parse through each link in the list and append a newline character to the end of a given link and then write that link + newline to the output file:
file = open('C:/Python34/census_links.csv', 'a')
# Simulating a list of links:
census_links = ['example.com', 'sample.org', 'xmpl.net']
for link in census_links:
file.write(link + '\n') # append a newline to each link
# as you process the links
file.close() # you will need to close the file to be able to
# ensure all the data is written.
print(x, file=f) is another way to do f.write(x + '\n').
E. Ducateme has already answered the question, but you could also use the csv module (most of the code is from here):
import csv
# This is assuming that “census_links” is a list
census_links = ["Example.com", "StackOverflow.com", "Google.com"]
file = open('C:\Python34\census_links.csv', 'a')
writer = csv.writer(file)
for link in census_links:
writer.writerow([link])
