如何打印到文本文件？

Question

I want print my output to text file. Jow can I fix my code?

for h3 in parse.find_all('h3', {'class': "_1hETr2dodrTLejwpCPNjNp"}):
     account = '{}:{}:{}'.format(ab_form, ft_form, h3.get_text())
     print(account)
     output = open("./output.txt", "r")
     output.write(account)

Answer 1

You need a + in your file open to create the file if it does not exist.

Also, there is little value opening the file each time through the loop.

with open("./output.txt", "a+") as fd:
  for h3 in parse.find_all('h3', {'class': "_1hETr2dodrTLejwpCPNjNp"}):
    account = '{}:{}:{}\n'.format(ab_form, ft_form, h3.get_text())
    fd.write(account)

I will assume that the rest of the script does what you need it to do.

Answer 2

    for h3 in parse.find_all('h3', {'class': "_1hETr2dodrTLejwpCPNjNp"}):
        account = '{}:{}:{}\n'.format(ab_form, ft_form, h3.get_text())
        with open("./output.txt", "a") as fd:
            fd.write(account)

note \\n newline separator and 'a' append mode as you are doing multiple writes
