Menu
Really simple, I want to create a temporary html page that I display with the usual webbrowser.
Why does the following code produce an empty page?
import tempfile
import webbrowser
import time
with tempfile.NamedTemporaryFile('r+', suffix = '.html') as f:
f.write('<html><body><h1>Test</h1></body></html>')
webbrowser.open('file://' + f.name)
time.sleep(1) # to prevent the file from dying before displayed

open() to open an HTML file within Python. Call codecs. open(filename, mode, encoding) with filename as the name of the HTML file, mode as "r" , and encoding as "utf-8" to open an HTML file in read-only mode.
Because your file doesn't exist on the disk and sits entirely in memory. That's why the browser starts but opens nothing since no code has been provided.
Try this:
#!/usr/bin/python
import tempfile
import webbrowser
tmp=tempfile.NamedTemporaryFile(delete=False)
path=tmp.name+'.html'
f=open(path, 'w')
f.write("<html><body><h1>Test</h1></body></html>")
f.close()
webbrowser.open('file://' + path)
