soup = BeautifulSoup(html_page, "lxml")

for tag in tags:

    t = tag.get('href')

    x = t.find('watch?v')

      if x > 0:

        with open("C:BGOutput.txt", "a+") as text_file:

        text_file.write("Links are :: " % x)

I am trying to write to file called output.txt rather than print on screen.
Also I want to skip writing to file if contain text "google"

How can I do that
But this code is not doing it

In regards to program not writing to file

It looks like there is an issue with your code indentation. If you move the line text_file.write("Links are :: " % x) one indent level futher to the right, it may solve your problem.

In regards to checking links the link to google

You might try using String.index() (linked here) to see if you can find an occurrence of 'google.com'.

if 'watch?v' in t and 'google' not in t:

    with open("Output.txt", "a+") as text_file:

        text_file.write("Links are :: " + t)

        text_file.write('n')

Its simple text in string gives match text not in works for tag not having google

Output

Links are :: /watch?v=rb8K4nv2y7A

Links are :: /watch?v=rb8K4nv2y7A

.

.

you have two error here:

text_file.write("Links are :: " % x)

first no %s where variables should be inserted, second x is index it should be t.

for performance it better to open file outside loop

with open("C:BGOutput.txt", "a+") as text_file:

    for tag in tags:

        t = tag.get('href')

        x = t.find('watch?v')

        # if 'watch?v' in t:

        # or

        if x > 0:

            text_file.write("Links are :: %sn" % t)

            # or

            # text_file.write("Links are :: " + t + "n")
