Python – Googletrans for multiple txt files in loop

Question

I’m seeking to run googletrans to translate a series of 300 .txt files in a single folder. I’m struggling to construct a loop that will allow me to run a translation of each file and write the output in new .txt files. Googletrans has a limit on bulk translations, so I’m happy to limit the iterations to 50 files at a time.

Here’s the code for translating a single file. It prints the original txt file, then the translated file, and finally outputs the file into a new txt file.

from googletrans import Translator

f = open('Translation Projectpage_323.txt', 'r')

if f.mode == 'r':
    contents = f.read()
    print(contents)

translator = Translator()
result = translator.translate(contents, dest='en')
print(result.text)

with open('Translation Projecttrans_page_323.txt', 'w') as f:
    f.write(result.text)

Any thoughts? New to Python and still wrapping my head around loops.

Assuming that there are 999 pages, the files are formatted as trans_page_1.txt rather than trans_page_001.txt, and that the first page is page 1, not page 0:

from googletrans import Translator
translator = Translator()

for page_number in range(1, 999):

    f = open(f'Translation Projectpage_{page_number}.txt', 'r')

    if f.mode == 'r':
        contents = f.read()
        print(contents)


    result = translator.translate(contents, dest='en')
    print(result.text)

    with open(f'Translation Projecttrans_page_{page_number}.txt', 'w') as f:
        f.write(result.text)

This doesn’t limit the files translated, but you can do this by changing the maximum page to 50 or by doing some other code shenanigans.
