python csv 写入两列

Question

I am trying to write the output of a python calculation to csv in two columns. I tried the following to achieve this, but failed.

import csv

with open('data.csv', 'ab') as f:
    writer = csv.writer(f)
    for row in [level, variable]:
        writer.writerow([row])

the print output of print(level, variable) is as follows,

(1, 0)
(2, 0)
---
---
---
(33, 8)
(34, 7)
(35, 6)
(1, 0)
(2, 0)
---
---
---
(33, 10)
(34, 1)
(35, 2)

How can I write this print output in to two columns of csv file? Can anyone give a answer? Thanks in advance!

Answer 1

A csv is literally just a file with C omma S eperated V alues. So technically:

f = open("whatever.csv")
[for loop]
    f.write(f"{value1}, {value2}\n")
f.close()

should do the trick. Where value1 and value2 are the name of your 2 values.

Answer 2

Can you try this.

  import csv
    
    with open('data.csv', 'w') as f:
        writer = csv.writer(f)
        writer.writerows(zip(level, variable))

you can also try

f=open(data.csv,'w')
for i,j in zip(level,variable):
    f.write(str(i)+","+str(j))
f.close()

Just an idea, but you should try to:

• Build a list
• Put in your list your tuples (python identifies tuples with parenthesis)
• Send your list of tuples in your csv
