如何在循环中保存变量的结果

results = []
for i in range(1, 10):
    result = i * 2
    results.append(result)
    
print(results)  # 输出 [2, 4, 6, 8, 10, 12, 14, 16, 18]

results = {}
for i in range(1, 10):
    result = i * 2
    results[i] = result
    
print(results)  # 输出 {1: 2, 2: 4, 3: 6, 4: 8, 5: 10, 6: 12, 7: 14, 8: 16, 9: 18}

def generate_results():
    for i in range(1, 10):
        result = i * 2
        yield result
        
results = generate_results()

for result in results:
    print(result)
