[FIXED] How to convert key value pairs of rcParams to dictionary

Issue

I want to get key:value pairs of rcParams for further manipulation.

from matplotlib import rcParams 
x = rcParams
print(x)

Yeilds:

_internal.classic_mode: False
agg.path.chunksize: 0
animation.bitrate: -1
animation.codec: h264
animation.convert_args: ['-layers', 'OptimizePlus']
animation.convert_path: convert
...

I tried this approach:

for line in x:
    print(line)

It only yielded the keys but not the values:

_internal.classic_mode
agg.path.chunksize
animation.bitrate
animation.codec
animation.convert_args
animation.convert_path
...

Lastly I tried this:

for line in x:
    for key, value in line:
        print(key, value)

And received the following error:

ValueError: not enough values to unpack (expected 2, got 1)

What should I try next?

Solution

rcParams is a subclass of dict, so you should already be able to perform dict methods on the object. That being said, if you need to take an dict-like object like this and turn it into a separate dictionary, you can do something like this:

from matplotlib import rcParams 

params = rcParams
new_params = {}

# with a simple for loop
for param in params:
    new_params[param] = params[param]
    
# or with the items() method
for param, value in params.items():
    new_params[param] = value
