如何简化包含多个条件的IF语句

if condition1 and condition2:
    # 执行代码块

if condition1:
    # 执行代码块
elif condition2:
    # 执行代码块

conditions = {
    'condition1': code_block1,
    'condition2': code_block2,
    # 其他条件和代码块
}

if condition in conditions:
    conditions[condition]()

def code_block1():
    # 执行代码块

def code_block2():
    # 执行代码块

# 调用函数
if condition == 'condition1':
    code_block1()
elif condition == 'condition2':
    code_block2()

# 调用类方法
class CodeBlock:
    def code_block1(self):
        # 执行代码块

    def code_block2(self):
        # 执行代码块

code_block = CodeBlock()

if condition == 'condition1':
    code_block.code_block1()
elif condition == 'condition2':
    code_block.code_block2()
