python switch case statement

Python doesn't have switch case statements.

But I found code that will simulate a switch case statement

result = {
  'a': lambda x: x * 5,
  'b': lambda x: x + 7,
  'c': lambda x: x - 2
}[value](x)

to catch an error if no key found

try:
    {'option1': function1,
     'option2': function2,
     'option3': function3,
     'option4': function4}[value]()
except KeyError:
    # default action

I would probably use

switch = {'option1': function1,
     'option2': function2,
     'option3': function3,
     'option4': function4}
if value in switch:
     switch[value]()
else:
     pass
     #default
