Scientific Computing with Python Projects - Time Calculator

Tell us what’s happening:

Hi!

I have just completed the Time Calculator project. All results are as expected, but none of the tests will pass.

Any ideas?

```py
import re

def add_time(start, duration, day = None):

start_hour = re.findall("[0-9]+:", start)[0][:-1]
start_minute = re.findall(":[0-9]+", start)[0][1:]
duration_hour = re.findall("[0-9]+:", duration)[0][:-1]
duration_minute = re.findall(":[0-9]+", duration)[0][1:]

hours_sum = int(start_hour) + int(duration_hour)
minutes_sum = int(start_minute) + int(duration_minute)
start_period = re.findall("AM|PM", start, re.IGNORECASE)[0].upper()

# convert hours
if minutes_sum < 60:
new_hour = hours_sum % 12
else:
new_hour = (hours_sum + 1) % 12

if new_hour == 0:
new_hour = "12"

# convert minutes
new_minute = (minutes_sum) % 60
if new_minute < 10:
new_minute = f"0{new_minute}"

# swap period when necessary
if (hours_sum % 12) == 11:
if minutes_sum >= 60:
periods_passed = (hours_sum // 12) + 1
else:
periods_passed = hours_sum // 12
else:
periods_passed = hours_sum // 12

if periods_passed % 2 != 0:
if start_period == "AM":
new_period = "PM"
else:
new_period = "AM"
else:
new_period = start_period

# calculate days passed
if start_period == "PM" and periods_passed % 2 != 0:
days_passed = (periods_passed // 2) + 1
else:
days_passed = periods_passed // 2

if days_passed == 0:
days_later = 0
elif days_passed == 1:
days_later = "next day"
else: days_later = f"{days_passed} days later"

# present answer (day = None)
if not day:
if days_later == 0:
print(f"{new_hour}:{new_minute} {new_period}")
else:
print(f"{new_hour}:{new_minute} {new_period} ({days_later})")

# calculate new day
days_of_week = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
if day:
start_day = re.findall("[a-z]+", day, re.IGNORECASE)[0].lower().capitalize()
for weekday in days_of_week:
if weekday == start_day:
start_day_index = days_of_week.index(weekday)
new_day = days_of_week[(start_day_index + days_passed) % 7]

if days_later == 0:
print(f"{new_hour}:{new_minute} {new_period}, {new_day}")
else:
print(f"{new_hour}:{new_minute} {new_period}, {new_day} ({days_later})")
