Why does using Python’s print() function cause a rendering error in Django, and what should be passed to render() instead?

Problem Code Snippet (Python: Django)-

def home(request):
    data = {"msg": "Hello"}
    result = print(data)   # Problematic line
    return render(request, "index.html", result) # why render? Is there any other way?

have you checked what print(data) returns ? what do you see? i guess you see None. If you pass a None to a context you surely will have an error. try passing the dictionary instead and let me know, if it worked or not.

print has no return value, or rather, it returns None

render need needs such parameters:

render(request, "index.html", XX=YY)

The {{ XX }} in the template index.html will be rendered rendered as YY
