如果有任何字符串形式和列表形式的数学表达式，你将如何在Python中解决它？

expression = "2 + 3 * 4"
result = eval(expression)
print(result)  # 输出：14

import operator

def evaluate_expression(expression):
    operators = {
        '+': operator.add,
        '-': operator.sub,
        '*': operator.mul,
        '/': operator.truediv
    }
    
    stack = []
    for token in expression:
        if token.isdigit():
            stack.append(float(token))
        elif token in operators:
            b = stack.pop()
            a = stack.pop()
            op = operators[token]
            result = op(a, b)
            stack.append(result)
    
    return stack[0]

expression = ['2', '+', '3', '*', '4']
result = evaluate_expression(expression)
print(result)  # 输出：14.0
