<｜begin▁of▁sentence｜>### Instruction:
Assuming you have adjusted certain parameters in the igraph configuration and now need to save these settings, how would you save this configuration to a specific file, or the default user-level configuration file if no filename is specified?
### Response:
from igraph import Configuration

# Initialize the Configuration object
config = Configuration.instance()

# Set a configuration parameter (just for demonstration)
config['graphics'] = 'png'

# Save the configuration to a file
config.save('config.txt')

# Save the configuration to the user-level configuration file (default location)
#config.save()
