有多种方法可以简化if/else代码块,以下是一些常见的技巧:
result = "Yes" if condition else "No"
actions = {
"condition1": action1,
"condition2": action2,
"condition3": action3,
}
result = actions.get(condition, default_action)()
def action1():
# do something
def action2():
# do something
def action3():
# do something
actions = {
"condition1": action1,
"condition2": action2,
"condition3": action3,
}
result = actions.get(condition, default_action)()
class Strategy:
def execute(self):
pass
class Strategy1(Strategy):
def execute(self):
# do something
class Strategy2(Strategy):
def execute(self):
# do something
class Strategy3(Strategy):
def execute(self):
# do something
strategies = {
"condition1": Strategy1(),
"condition2": Strategy2(),
"condition3": Strategy3(),
}
result = strategies.get(condition, default_strategy).execute()
这些方法可以根据具体的情况选择使用,以简化if/else代码块并提高代码的可读性和可维护性。
