Question

我正在尝试将某些数据从csv转换为特定的json数据结构，并具有以下单独示例格式的字符串： “ 8:30 AM-12:30 PM” “ 12:00 PM-2:00 PM” 其中“-”之前的时间是开始时间，而“-”之后的时间是结束时间。我一直试图将它们分成24hr格式的startTime和endTime两个变量。例子：

startTime = 0830 endTime = 1230

startTime = 1200 endTime = 1400

Answer 1

def get_24_format(time):
    timeinstr = ""
    if len(time.split(":")[0]) is 1:
        if time[len(time)-2] == 'A':
            timeinstr += "0{}".format(time.split(":")[0])
        else:
            timeinstr += "{}".format(int(time.split(":")[0])+12)
    else:
        if time[len(time)-2] == 'A':    
            timeinstr += "{}".format(time.split(":")[0])
        else:
            timeinstr += "{}".format(int(time.split(":")[0])+12)
    timeinstr += time.split(":")[1][:2]
    return timeinstr


# input your time here
# time = "11:00PM - 2:00AM" 
time = time.split("-")
time[0] = time[0].rstrip()
time[1] = time[1].lstrip()

timeinstr = "starttime " + get_24_format(time[0]) + " endtime " + get_24_format(time[1])

print(timeinstr)

尝试：

from datetime import *

time1 = "12:00PM - 2:00PM"

# Splitting the string into two parts (using the hyphen in between them) and storing them in two separate variables
# t1 = start time; t2 = end time
t1, t2 = time1.split(" - ")

# string manipulation to make the data feedable to datetime.strptime() 
t1 = t1.replace("AM", " AM").replace("PM", " PM")
t2 = t2.replace("AM", " AM").replace("PM", " PM")

# passing the data stored in our strings and converting it into 24hr format
t1 = datetime.strptime(t1, '%I:%M %p')
t1 = datetime.strftime(t1, "%H:%M")

t2 = datetime.strptime(t2, '%I:%M %p')
t2 = datetime.strftime(t2, "%H:%M")

print(t1)
print(t2)

输出：

12:00
14:00

需要帮助，将AM-PM统计结束时间字符串转换为Datetime 24hr
