Switch in Python

Question

I have tried making a switch like statement in python, instead of having a lot of if statements.

The code looks like this:

def findStuff(cds):
    L

There's nothing wrong with a long if:

if switch == 'case0':
   do_case0()
elif switch == 'case1':
   do_case1()
elif switch == 'case2':
   do_case2()
...

If that's too long winded, or if you have a lot of cases, put them in a dictionary:

switch = {'case0': do_case0, 'case1': do_case1, 'case2': do_case2, ...}
switch[case_variable]()
// Alternative:
(switch[case_variable]).__call__()

If your conditions are a bit more complex, you need to think a little about your data structures. e.g.:

switch = {(0,21): 'never have a pension',
          (21,50): 'might have a pension',
          (50,65): 'definitely have a pension',
          (65, 200): 'already collecting pension'}
for key, value in switch:
    if key[0] < case_var < key[1]:
        print(value)
