如何遍历两个并行的字典值列表？

Question

我需要帮助来遍历这个函数中名为'TimeO'和'TimeC'的数据字典列

Data_Dict = {'TimeO': ['9:00:00', '10:00:00'] 'TimeC': ['14:00:00', '16:00:00']}

x应该是来自TimeO的值，y应该是来自TimeC的值

我不知道如何迭代这些值

def timed_duration():
        opening = datetime.strptime(x, '%H:%M:%S')
        closing = datetime.strptime(y, '%H:%M:%S')
        sec =(closing-opening).total_seconds()
        hour = sec/3600
        return(hour)
timed_duration()

x和y应该遍历400条记录，但我不知道该怎么办

Answer 1

考虑到您的数据如下所示：

Data_Dict = {'TimeO': ['9:00:00', '10:00:00'], 'TimeC': ['14:00:00', '16:00:00']}

def timed_duration(data_dict):
    hours = []  # create an empty list to store all the results
    for x, y in zip(data_dict['TimeO'], data_dict['TimeC']):
        opening = datetime.strptime(x, '%H:%M:%S')
        closing = datetime.strptime(y, '%H:%M:%S')
        sec =(closing-opening).total_seconds()
        hour = sec/3600
        hours.append(hour)
    return hours  # no parenthesis in return

timed_duration(Data_Dict)

这将创建一个名为hours的列表，其中填充函数的结果。 zip()允许您同时遍历这两个对象
