Not sure why Im returning that may errors - Time Calculator freecodecamp

#1

My code is as follows but is returning errors on things that come our correct, not sure what is going on

def add_time(start, duration):
  am_pm = start.split()[-1]
  if am_pm == "AM":
    start_h = int((start.split()[0]).split(":")[0])*60
  else:
    start_h = (int((start.split()[0]).split(":")[0])+12)*60
  start_m = int((start.split()[0]).split(":")[-1])
  dur_h = int(duration.split(":")[0])*60
  dur_m = int(duration.split(":")[-1])
  start_both = start_h + start_m
  dur_both = dur_h + dur_m
  end_h24 = 0
  end_h12 = 0
  end_m = 0
  end_time = 0
  days_later = 0
  end_str = ""

  if (start_both + dur_both) > 1444:
    end_time = (start_both + dur_both)
    end_h24 = int((start_both + dur_both)/60)%24
    end_m = ((start_both + dur_both)%60)
    days_later = int((start_both + dur_both)/(24*60))
    if end_h24 > 11:
      am_pm = "PM"
    else:
      am_pm = "AM"
  elif (start_both + dur_both) > 720:
    end_time = (start_both + dur_both)
    end_h24= int((start_both + dur_both)/60)
    end_m = ((start_both + dur_both)%60)
    if end_h24 > 11:
      am_pm = "PM"
    else:
      am_pm = "AM"
  else:
    end_time = (start_both + dur_both)
    end_h24 = int((start_both + dur_both)/60)
    end_m = ((start_both + dur_both)%60)
    if end_h24 > 11:
      am_pm = "PM"
    else:
      am_pm = "AM"

  if days_later > 1:
    end_str = "(" + str(days_later)+" days later)"
  elif days_later > 0:
    end_str = "(next day)"
  else:
    end_str = ""
  
  if end_h24 > 12:
    end_h12 = end_h24 - 12
  else:
    end_h12 = end_h24
  
  if len(str(end_m)) > 1:
    print(str(end_h12)+ ":"+ str(end_m)+ " "+ am_pm +" "+ end_str)
  else: 
    print(str(end_h12)+ ":0"+ str(end_m)+ " "+ am_pm +" "+end_str)```

I don’t see any return statement in your code

but if you please post the link to your project it’s easier to debug

#3

hi there, the url to the project is https://www.freecodecamp.org/learn/scientific-computing-with-python/scientific-computing-with-python-projects/time-calculator

#4

to your project, that’s just the explanation page on fcc

the repl on which you are coding

#5
#6

your code returns Null, you need return statements in your code to give an output to the function

#8

i switched the print statements and added a return but still getting a lot of errors

#9

there are two types of error from your code, one is this:

TypeError: add_time() takes 2 positional arguments but 3 were given

your code can’t handle functions like add_time("11:30 AM", "2:32", "Monday")

the other type of error is AssertionError: None != '...'

your function still returns None, as that is the output from the print statement
