如何在python中对这两列进行舍入？

# 假设有两列数据存储在列表中
column1 = [1.234, 2.345, 3.456]
column2 = [4.567, 5.678, 6.789]

# 创建两个空列表用于存储舍入后的结果
rounded_column1 = []
rounded_column2 = []

# 遍历每个元素进行舍入操作，并将结果添加到对应的列表中
for num1, num2 in zip(column1, column2):
    rounded_num1 = round(num1, 2)
    rounded_num2 = round(num2, 2)
    rounded_column1.append(rounded_num1)
    rounded_column2.append(rounded_num2)

# 打印舍入后的结果
print(rounded_column1)
print(rounded_column2)
