better use popen

import os

process = os.popen('whoami')
myname = process.read()
process.close()
 
html_str = """
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
 
<h1>test</h1>
<p>My first paragraph.</p>
 
</body>
</html>
"""
 
html_str = html_str.replace("test", myname)

Html_file= open(r"/tmp/q.html","w")
Html_file.write(html_str)
Html_file.close()

to keep the result of popen for using it for replace in the html string.

you can name it whatever you want.

Can also show a example with Jinja2.
Jinja2 is build for stuff like this,it's mostly used with a running server to transport values to HTML on client side.
It also work fine on it's own.

from jinja2 import Environment, FileSystemLoader
import os

html_str = """\
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<h1>{{ test }}</h1>
<p>My first paragraph.</p>

</body>
</html>"""

process = os.popen('whoami')
myname = process.read().strip()
process.close()

# Print html
print(Environment().from_string(html_str).render(test=myname))

# Save html
#Environment().from_string(html_str).stream(test=myname).dump('name.html', encoding='utf-8')

Output:<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<h1>Pc User Name</h1>
<p>My first paragraph.</p>

</body>
</html>
