Q:

Unable to view image on my website when importing the image src from python list

<img src="{{ url_for('static' , filename = '{{ game["TEAM_1_IMAGE"] }}') }}" width="30" height="30">

I am using the above to display an image for which the image src is stored in a python list, but no image is being displayed. Please help! Thanks!
<img src="{{ url_for('static' , filename = 'game["TEAM_1_IMAGE"]') }}" width="30" height="30">

This also does not work and I just don't know why

A:

Try without quotes round that, assuming game['TEAM_1_IMAGE'] is available in the template:
<img src="{{ url_for('static', filename=game['TEAM_1_IMAGE']) }}" width="30" height="30" />

The mistake in your first codeblock is trying to nest Jinja expressions.  Avoid doing this.  
In the second codeblock, consider that filename is an argument to the url_for function.  The same rules apply within a template expression as if you were passing an argument to a function in pure python:
url_for('static', filename=game["TEAM_1_IMAGE"]) # Works

You can see that this passes the value of game["TEAM_1_IMAGE"] as the filename argument.
The mistake was trying to pass a string as the argument.
filename='game["TEAM_1_IMAGE"]'
