This is the code I am using and I am getting partial output
def main():
with open('time.txt') as f:
linenumber=0
for lines in f:
a=f.readlines()
for i in range(0,len(lines)):
print(a[i].split()[1],a[i].split()[3])
#print (a[i])
if __name__=='__main__':
main()
The txt file consists of the following elements: time.txt
and the output i am getting is output
here in the output the program is not printing till the end of the txt file , it is only printing till a certain line and stopping . dont know the reason.

Say you have a file called time.txt with the following contents that you know is VALID:

You could utilize a helper function to check if the possible parts of a line for a "starttime", end with am or pm:
def is_time(s: str) -> bool:
return s.endswith('am') or s.endswith('pm')
def main() -> None:
with open('time.txt', 'r') as log_file:
next(log_file) # Skip first line.
for line in log_file:
line_parts = line.split()
if line_parts[0].count('/') == 2: # Line starts with a date.
if is_time(line_parts[1]):
print(' '.join(line_parts[1:4]))
else:
if is_time(line_parts[0]):
print(' '.join(line_parts[0:3]))
if __name__ == '__main__':

To calculate the total hours you could parse each time interval into a timedelta:
from datetime import datetime, timedelta
def is_time(s: str) -> bool:
return s.endswith('am') or s.endswith('pm')
def parse_12_hour_time(time: str) -> datetime:
return datetime.strptime(time, '%I:%M%p')
def get_timedelta(start_time: str, end_time: str) -> timedelta:
return parse_12_hour_time(end_time) - parse_12_hour_time(start_time)
def timedelta_to_hours(td: timedelta) -> float:
return td.total_seconds() / 3600
def main() -> None:
total_hours = 0
with open('time.txt', 'r') as log_file:
next(log_file) # Skip first row.
for line in log_file:
line_parts = line.split()
if line_parts[0].count('/') == 2: # Line starts with a date.
if is_time(line_parts[1]):
td = get_timedelta(line_parts[1], line_parts[3])
total_hours = timedelta_to_hours(td)
else:
if is_time(line_parts[0]):
td = get_timedelta(line_parts[0], line_parts[2])
total_hours = timedelta_to_hours(td)
print(f'{total_hours = :.2f}')
if __name__ == '__main__':
main()
Output:
total_hours = 74.38
