Description

Python3.x integrates the operation of csv files and can be directly introduced into the package, but python2.x needs to be installed separately.

Actual combat

1. Read csv file

# introduce package import csv# to open the file csvfile = open ('xiaoqiang.csv',newline='') # get the object csvReader = csv.reader (csvfile) # read the contents and print for content in csvReader: print (content) # off. Some friends often forget that some people in the group have encountered this problem today, csvfile.close ()

2. Write to csv file

# introduce the package import csv# to open the file csvfile = open ('xiaoqiang.csv', 'wicked journal new lineages') # get the object writer = csv.writer (csvfile) # write a row of data writer.writerow (('name', 'URL')) # define the content rows= to write multiple lines of data [('Xiaoqiang's blog', 'https://blog.51cto.com/xqtesting'), (' Xiaoqiang's video') 'http://edu.51cto.com/lecturer/4626073.html')]# writes multiline writer.writerows (rows) # turns off csvfile.close ()
