invalid syntax of render2D about concept HOT 2 CLOSED

Hello @wuchenglon. The different items within Python dictionaries need to be separated by commas (,). You currently have this:

output_times = {
    'snapshot': a_begin
    'render2D': a_begin
}

but need to add a comma like so:

output_times = {
    'snapshot': a_begin,
    'render2D': a_begin
}

(you even see that the syntax highlighting here on GitHub is not happy about the first case).
Since Python allows trailing commas, I recommend adding one more comma:

output_times = {
    'snapshot': a_begin,
    'render2D': a_begin,
}

(this way, you won't forget the comma if you one day add another item/line).

Note that the above is purely about Python syntax, it is not specific to CONCEPT. You have the same issue for output_dirs.

A separate issue is your way of defining H0:

H0 = 67km/(sMpc)

You need to write this as

H0 = 67*km/(s*Mpc)

as 1) Python does not understand things like 67km and 2) CONCEPT only defines individual "basic" units, like s and Mpc, not products like sMpc = s*Mpc.

May I ask whether you've written these parameter definitions out yourself, or have you obtained them from copying code from somewhere (e.g. the documentation)?

Hi jmd-dk, thank you for your careful guidance. Indeed I learned and copied code from https://jmd-dk.github.io/concept/ and example_basic from concept/param and it's my fault that lack of inspection, now I get the file what I want.
Thanks again for your generous help.
