I am currently developing a Youtube audio sampling program with an object named time_snip that stores the start and end times of a sample in milliseconds. I have encountered a situation where entering the time correctly gives the expected output, but typing the time in the wrong format (handled by a try/except exception) and then entering it correctly results in an
AttributeError: 'NoneType' object has no attribute 'start'The time_snip class definition is as follows:
class time_snip:
def __init__(self,start_hour,start_min,start_sec,start_msec,end_hour,end_min,end_sec,end_msec):
self.start = (start_hour*60*60*1000)+(start_min * 60 * 1000) + (start_sec * 1000)+(start_msec)
self.end = (end_hour*60*60*1000)+(end_min * 60 * 1000) + (end_sec * 1000)+(end_msec)
self.start_ind = (str(start_min)+':'+str(start_sec))
self.end_ind =(str(end_min)+':'+str(end_sec))
Main code snippet:
from pytube import YouTube
from TimeSnip import time_snip
time_options = input("Would you like to find by time(1) or by word(2)?: ")
url ="https://www.youtube.com/watch?v=vGwNPeEXEDM&ab_channel=SilasLaspada"
ytd = YouTube(URL)
# Function to set time values
def time_set(youtube_object):
try:
hr_length = int(ytd.length/3600)
min_length = int((ytd.length%3600)/60)
sec_length = ytd.length%60
print("the video is " + str(hr_length)+':'+str(min_length)+':'+str(sec_length) +'long')
start_time_srt_format = input("Enter start time in 'hr:min:sec,msec' format: ")
end_time_srt_format = input("Enter end time in 'hr:min:sec,msec' format: ")
start_parts = start_time_srt_format.split(':')
end_parts = end_time_srt_format.split(':')
start_secmsec = start_parts[2].split(',')
end_secmsec = end_parts[2].split(',')
start_hr = int(start_parts[0])
start_min = int(start_parts[1])
start_sec = int(start_secmsec[0])
start_msec = int(start_secmsec[1])
end_hr = int(end_parts[0])
end_min = int(end_parts[1])
end_sec = int(end_secmsec[0])
end_msec = int(end_secmsec[1])
word = (str(start_sec)+'-'+str(end_sec))
timeSnip = time_snip(start_hr, start_min, start_sec, start_msec, end_hr, end_min,end_sec,end_msec)
return timeSnip
except IndexError:
print("Invalid input! Try again!")
time_set(youtube_object)
if time_options =='1':
timeSnip = time_set(ytd)
word = str(timeSnip.start/1000)+' sec'
elif time_options =='2':
word = input("Enter word: ")
This issue is perplexing me, as I cannot understand why it occurs.
