I'm following the code from the following question (reproduced below):
def response(flow):
print("")
print("="*50)
print(flow.request.method + " " + flow.request.path + " " + flow.request.http_version)
print("-"*25 + " request headers " + "-"*25)
for k, v in flow.request.headers.items():
print("%-30s: %s" % (k.upper(), v))
print("-"*25 + " response headers " + "-"*25)
for k, v in flow.response.headers.items():
print("%-30s: %s" % (k.upper(), v))
print("-"*25 + " body (first 100 bytes) " + "-"*25)
print(flow.request.content[0:100])
I have trouble understanding where, when using mitmproxy, you find the flow variable. How do you connect mitmproxy such that you could receive that flow of requests?
I was wrong. It looks like you pass in the script with the -s flag Something like:
mitmproxy -s myscript.py
Basically you pass in the file name and mitmproxy will load it and call the request() function, passing in the flow variable you mentioned.
I think reading these two pages might help. Note that they have different kinds of add-ons. I think the simple classless request() function you have would make it a 'script' type.

There are also more examples in the docs. Also, I've found this GitHub repo to be helpful for examples:
