How to refactor many ifs and else with different conditions in python?

December 1, 2021

I have many ifs and elses that assign a variable an X value. Does anyone have any idea how to try to improve this code?

I’ve searched for several ideas on the internet, but I haven’t found anything that would help me in this specific case.

date1 = ''
date2 = ''
name = ''

query = ''

if date1 and date2 and name:
    query = 'query 1'
elif date1 and date1:
    query = 'query 2'
elif date1 and name:
    query = 'query 3'
else:
    query = 'query default'

>Solution :

You can try mapping your input values to queries

# map (date1, date2, name) => query
query_map = {
    (date1, None, None): query1,
    (None, date2, None): query2,
    (date1, None, name): query3,
}

query = query_map.get((input_date1, input_date2, input_name), "default_query")
