While other questions have tackled the broader category of sequences and modules, I ask this very specific question:

"What naming convention do you use for dictionaries and why?"

Some naming convention samples I have been considering:

# 'value' is the data type stored in the map, while 'key' is the type of key
value_for_key={key1:value1, key2,value2}
value_key={key1:value1, key2,value2}
v_value_k_key={key1:value1, key2,value2}

Don't bother answering the 'why' with "because my work tells me to", not very helpful. The reason driving the choice is more important. Are there any other good considerations for a dictionary naming convention aside from readability?
