Replacements for switch statement in Python?
In Python, the if-elif-else statement can be used as a replacement for a switch statement. Additionally, the dict.get() method or a dictionary of functions can also be used to achieve a similar effect.
Here are a few examples of using the if-elif-else statement as a replacement for a switch statement in Python:
def switch_example(case):
if case == 'a':
return 'Case A'
elif case == 'b':
return 'Case B'
elif case == 'c':
return 'Case C'
else:
return 'Other Case'
print(switch_example('a')) # 'Case A'
print(switch_example('b')) # 'Case B'
print(switch_example('c')) # 'Case C'
print(switch_example('d')) # 'Other Case'
Here is an example of using the dict.get() method as a replacement for a switch statement in Python:
def switch_example(case):
options = {
'a': 'Case A',
'b': 'Case B',
'c': 'Case C',
}
return options.get(case, 'Other Case')
print(switch_example('a')) # 'Case A'
print(switch_example('b')) # 'Case B'
print(switch_example('c')) # 'Case C'
print(switch_example('d')) # 'Other Case'
And here is an example of using a dictionary of functions as a replacement for a switch statement in Python:
def case_a():
return 'Case A'
def case_b():
return 'Case B'
def case_c():
return 'Case C'
def other_case():
return 'Other Case'
def switch_example(case):
options = {
'a': case_a,
'b': case_b,
'c': case_c,
}
return options.get(case, other_case)()
print(switch_example('a')) # 'Case A'
print(switch_example('b')) # 'Case B'
print(switch_example('c')) # 'Case C'
print(switch_example('d')) # 'Other Case'
All of the above examples show different ways of achieving similar functionality as switch statements in python.
