I was bored and came across a post about reading and writing csv files. As a newbie in testing, I have always been fond of python. On a whim, I decided to play with it and share it with those who need it. Bai, for the python masters, it is simply childish. For a testing novice like me, seeing the code is like getting a shot of chicken blood. Well, good stuff, good stuff!

How to write to csv in python

Writing of csv files: (Recommended learning: Python video tutorial)

stu1 = ['marry',26]
stu2 = ['bob',23]

Writing The first step is also to open the file. Because we want to write, the mode we use is the 'a' mode to append content. As for "newline=", it means that because of the type of our csv file, if we do not add this , when we write something, a blank line will appear. You can try this without adding it, or you can "Old Turtle's Butt" (regulation)

out = open('Stu_csv.csv','a', newline='')

Let's define a variable below. Write, pass in the file variable just now, dialect is to define the type of the file, we define it as excel type

csv_write = csv.writer(out,dialect='excel')

and then write the data, blah blah blah, it is finally over, write The method is writerow. By writing the mode object, calling the method to write

csv_write.writerow(stu1)
csv_write.writerow(stu2)

Finally, all newbies can use the syntax you are most familiar with to finish beautifully, 66666

    print ("write over")
