我想从数据框中的时间戳列中查找白天还是晚上。时间戳列的值如下： 20：0，14:30，6:15，5：0，4：0等

I want to find out whether it is day or night from the "timestamp" column in my data frame. The time stamp columns have values as follows: 20:0 , 14:30, 6:15, 5:0, 4:0 etc.

I使用了for循环，但它是日夜随机产生的。

I used a for loop but it randomly generated day and night.

for x in data['timestamp']: if x> '12:00': print('Day') else: print('Night')

我想在我的时间戳列旁边添加一列，当时间戳在6:00 am到18:00之间时，列的值为 Day；当时间戳为0时，列的值为 Night在18:01到5:59上午之间。

I want a column beside my timestamp column which has values as "Day" whenever the timestamp is between 6:00am to 18:00 and "Night" when the timestamp is between 18:01 to 5:59 am.

推荐答案

timestamp = ['6:00', '18:00', '18:01', '5:59'] for time in timestamp: hourMin = time.split(":") hour = int(hourMin[0]) mint = int(hourMin[1]) if hour>= 6 and hour <= 18: if(hour == 18): if(mint > 0): print("Night\n") else: print("Day\n") else: print("Day\n") else: print("Night\n")
