Copy text from environment variable and paste in Selenium (Python)

Question

I'm trying to paste a massive amount of text to an input element with Selenium using Python 3.8 on an Ubuntu OS. I can iterate over my string and send_keys, but that takes more than 60 seconds. I was hoping I could copy my text from my Python code and paste into the session with Ctrl + V:

I wish this worked...

# How big do you want your character chunks?
n_chunk_size = 500

if len(keyphrase)>n_chunk_size:
    pyperclip.copy(keyphrase)
    input_element.send_keys(Keys.CONTROL, 'v')

Slow way:

from textwrap import wrap
for k in wrap(keyphrase, n_chunk_size):
    input_element.send_keys(k)

Answer 1

So, this answer, actually, differs. If the textbox that you're working with is for a company, chances are that the input textbox might have a maxcharacter limit. So, you might need to check the length of your string prior to inserting it into the textbox.

For this example, I used the W3Schools input textbox and inserted my environment variables into the textbox. In this example, I imported

import os as OperatingSystem

and was able to get my computer's environment variables using this command:

# Get our operating system's environment information
environment_info = str(OperatingSystem.environ)

From there, I was able to create a for-loop that checked the input text of our textbox and compared the length of the input text to our environment_info's length.
