I am a beginner python user and I am stuck with a time-calculator program I am trying to create as part of an online certification. The program will calculate in an AM/PM format the time it is added from the initial time and the correct weekday. I have been having problems with this part as for reasons unknown to me the functions restart after having found the new weekday, assigning the integer "2" from the variable weekday and then breaking.
Here is the code snippet:
day_names = [
"monday",
"tuesday",
"wednesday",
"thursday",
"friday",
"saturday",
"sunday",
]
def weekday_calculator( weekday, day_count, new_hour, new_minute,): # this function calculates the right weekday for the new time
> print(f"starting weekday:{weekday}")
> weekday = weekday.lower()
> starting_day_index = day_names.index(weekday)
> print(f"This is the starting day of the week's index: {starting_day_index}")
> print(f"This is the day count {day_count}")
> weekday_calculate = starting_day_index day_count
> if weekday_calculate <= 6:
>> new_weekday = day_names[weekday_calculate] # to be fixed
>> print(f"This is the new weekday {new_weekday}")
>> result_printer(new_hour, new_minute, new_am_pm, day_count, new_weekday)
> elif weekday_calculate > 6:
>> print("let's adjust the weekday")
>> adjust_weekday(define_weekday)
weekday_calculator(weekday = "tuesday", daycount = 1) #this is only the data relevant to this snippet
This is the expected output:
Let's calculate the weekday
starting weekday:tuesday
This is the starting day of the week's index: 1
This is the day count 1
This is the new weekday Wednesday
(proceeds to the next function)
This is what has been happening
Let's calculate the weekday
starting weekday:tuesday
This is the starting day of the week's index: 1
This is the day count 1
This is the new weekday wednesday
tuesday
starting weekday:2
Traceback (most recent call last) line 52, in weekday_calculator
weekday = weekday.lower()
AttributeError: 'int' object has no attribute 'lower' # of course that is because you cannot change an integer to lower
Does anyone have an idea on how to fix this problem? I have no idea where the value "2" for weekday is coming from, and neither why the function is repeating itself instead of directly jump to the next one once at the end of the if statement. I have tried to change the structure of the function and the variable names so that the program does not make confusion between weekday and new weekday, but to no avail.
As you rightly requested, I have edited the post and added the rest of the code:
day_names = [
"monday",
"tuesday",
"wednesday",
"thursday",
"friday",
"saturday",
"sunday",

new_time = [new_hour, new_minute]
for number in new_time:
if number < 10:
return f"0{number}"
if day_count != 0:
if day_count == 1:
day = "(next day)"
else:
day = f"({day_count} days later)"
print(f"{new_time[0]}:{new_time[1]} {new_am_pm}, {weekday} {day}")

define_weekday,
): # this is to adjust the weekday index if it is more than 6
adjusted_weekday = day_names[define_weekday % len(day_names)]
print((adjusted_weekday))

weekday, day_count, new_hour, new_minute, new_am_pm

When I ran your code removing result_printer and adjust_weekday calls as i don't have it in the code you sent, my output is
starting weekday:tuesday
This is the starting day of the week's index: 1
This is the day count 1
This is the new weekday wednesday
I believe the problem comes from the other functions result_printer and adjust_weekday, returning an index instead of the str value.
Maybe send this two functions code to help us to find the problem
EDIT:
so here is your problem:
in time_calculator(), you call weekday_calculator(new_hour, new_minute, new_am_pm, weekday, day_count)
but weekday_calculator is defined with parameter weekday, day_count, new_hour, new_minute, new_am_pm, you cannot use the parameters so in an other order, you should specify your parameters names as
weekday_calculator(new_hour=new_hour, new_minute=new_minute, new_am_pm=new_am_pm, weekday=weekday, day_count=day_count)
or use the parameters in the same order than defined:weekday_calculator(weekday, day_count, new_hour, new_minute, new_am_pm)
CodePudding user response：
your problem is here: starting weekday:2 should be string, not int.
CodePudding user response：
The problem is in your time_calculator function. In the last few lines you first call day_calculator(new_hour, new_minute, new_am_pm, am_pm, weekday, day_count) which in turn calls weekday_calculator (this is fine). However, in the next two lines you also call weekday_calculator with completely wrong arguments.
Your function defines the arguments as weekday, day_count, new_hour, new_minute, new_am_pm.
But looking at the call to the function, you pass new_hour, new_minute, new_am_pm, weekday, day_count.
