Ian hates doing his laundry. But he loves to wear a clean t-shirt every day. He also loves to attend
different programming events where he receives a new (clean) t-shirt.
Ian starts with N clean t-shirts. The number of events coming up is M in the next D days. These
three parameters will be the first line of the program input.
The second line of the input will be the days with scheduled events: day 1, day 5, day 16 and so on.
The number of these days must match the M.
The output: the number of times that Ian will have to do the laundry in the next D days.

I tried starting it like this:

T = int(input("Number of clean original T-shirts:"))
while True:
if T<0:
T = int(input("Incorrect. Number of clean original T-shirts:"))
continue
else:
break
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))
while True:
if event > day:
event = int(input("Incorrect. Number of Events coming up:"))
day = int(input("Incorrect. How many days are the events spread over:"))
continue
else:
break

but I dont know what to do after

Code:

# Taking input for days with scheduled events
event_days = []
for i in range(event):
day_number = int(input(f"Enter day number for event {i+1}: "))
event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Counting the number of times Ian needs to do laundry
laundry_count = 0
current_tshirts = T

for i in range(1, day+1):
if i in event_days:
# Ian attends an event on this day
current_tshirts += 1 # Ian receives a new clean t-shirt
else:
# Ian doesn't have an event on this day
if current_tshirts == 0:
# Ian has no clean t-shirts, needs to do laundry
laundry_count += 1
current_tshirts = T # Reset the count after doing laundry
else:
current_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")

Opps!

Code:

# Taking input for days with scheduled events
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))

event_days = []
for i in range(event):
day_number = int(input(f"Enter day number for event {i+1}: "))
event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Counting the number of times Ian needs to do laundry
laundry_count = 0
current_tshirts = T

for i in range(1, day+1):
if i in event_days:
# Ian attends an event on this day
current_tshirts += 1 # Ian receives a new clean t-shirt
else:
# Ian doesn't have an event on this day
if current_tshirts == 0:
# Ian has no clean t-shirts, needs to do laundry
laundry_count += 1
current_tshirts = T # Reset the count after doing laundry
else:
current_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")

Try this!

I got this :

line 15, in <module>
current_tshirts = T
NameError: name 'T' is not defined

Also I think that you have to ask how many tshirts ian has
According to the teacher:

The input will be 1 1 10 10 and the output will be 9
Basically 1 clean shirt, 1 event, 10 days, event on day 10.

Try this code

Code:

# Taking input for the initial number of clean T-shirts
T = int(input("Number of clean original T-shirts:"))
while True:
if T <= 0:
T = int(input("Incorrect. Number of clean original T-shirts must be greater than 0:"))
continue
else:
break

# Taking input for other parameters
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))

# Taking input for days with scheduled events
event_days = []
for i in range(event):
day_number = int(input(f"Enter day number for event {i+1}: "))
event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Counting the number of times Ian needs to do laundry
laundry_count = 0
current_tshirts = T

for i in range(1, day+1):
if i in event_days:
# Ian attends an event on this day
current_tshirts += 1 # Ian receives a new clean t-shirt
else:
# Ian doesn't have an event on this day
if current_tshirts == 0:
# Ian has no clean t-shirts, needs to do laundry
laundry_count += 1
current_tshirts = T # Reset the count after doing laundry
else:
current_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")

No problem I think you are getting very close, it just doesnt give the correct number:

Number of clean original T-shirts:1
Number of Events coming up:1
How many days are the events spread over:10
Enter day number for event 1: 10
Ian will have to do laundry 4 times in the next 10 days.

He should be doing the laundry 9 times

hey I got the exact same issue with the same number(kinda funny)

Number of clean original T-shirts:1
Number of Events coming up:1
How many days are the events spread over:10
Enter day number for event 1: 10
Ian will have to do laundry 4 times in the next 10 days.

as i said b4 its supposed to be 9

I was thinking what if you make a total shirt number, and also on an event day shouldnt you add one to total number of shirts and add one dirty shirt?

One last shot:

Code:

# Taking input for the initial number of clean T-shirts
T = int(input("Number of clean original T-shirts:"))
while T <= 0:
T = int(input("Incorrect. Number of clean original T-shirts must be greater than 0:"))

# Taking input for other parameters
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))

# Taking input for days with scheduled events
event_days = []
for i in range(event):
day_number = int(input(f"Enter day number for event {i+1}: "))
event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Counting the number of times Ian needs to do laundry
laundry_count = 0
current_tshirts = T # Initialize with original number of clean T-shirts
total_tshirts = T # Total number of T-shirts Ian has including clean and dirty ones

for i in range(1, day+1):
if i in event_days:
# Ian attends an event on this day
total_tshirts += 1 # Ian receives a new clean t-shirt
current_tshirts += 1 # Ian receives a new clean t-shirt
else:
# Ian doesn't have an event on this day
if current_tshirts == 0:
# Ian has no clean t-shirts, needs to do laundry
laundry_count += 1
current_tshirts = total_tshirts # Reset to total count after doing laundry
current_tshirts -= 1 # Ian wears a clean t-shirt
else:
current_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")

OK THATS IMPROVEMENT

Number of clean original T-shirts:1
Number of Events coming up:1
How many days are the events spread over:10
Enter day number for event 1: 10
Ian will have to do laundry 8 times in the next 10 days.

the actual answer is 9 you're getting closer Grinning Face

Does this one work?

How do you test your Python code? Do you use an online parser?

Code:

# Taking input for the initial number of clean T-shirts
T = int(input("Number of clean original T-shirts:"))
while T <= 0:
   T = int(input("Incorrect. Number of clean original T-shirts must be greater than 0:"))

# Taking input for other parameters
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))

# Taking input for days with scheduled events
event_days = []
for i in range(event):
   day_number = int(input(f"Enter day number for event {i+1}: "))
   event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Counting the number of times Ian needs to do laundry
laundry_count = 0
current_tshirts = T # Initialize with original number of clean T-shirts

for i in range(1, day+1):
   if i in event_days:
   # Ian attends an event on this day
   current_tshirts += 1 # Ian receives a new clean t-shirt
   else:
   # Ian doesn't have an event on this day
   if current_tshirts == 0:
   # Ian has no clean t-shirts, needs to do laundry
   laundry_count += 1
   current_tshirts = 1 # Ian starts the day with a clean t-shirt
   else:
   current_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")

nope went back to 4

Number of clean original T-shirts:1
Number of Events coming up:1
How many days are the events spread over:10
Enter day number for event 1: 10
Ian will have to do laundry 4 times in the next 10 days.

I downloaded the IDLE python shell thing on my computer
you can probably find it on the official python website

Okay, with this code:

Code:

# Taking input for the initial number of clean T-shirts
T = int(input("Number of clean original T-shirts:"))
while T <= 0:
T = int(input("Incorrect. Number of clean original T-shirts must be greater than 0:"))

# Taking input for other parameters
event = int(input("Number of Events coming up:"))
day = int(input("How many days are the events spread over:"))

# Taking input for days with scheduled events
event_days = []
for i in range(event):
day_number = int(input(f"Enter day number for event {i+1}: "))
event_days.append(day_number)

# Sorting the event days in ascending order
event_days.sort()

# Initialize variables
laundry_count = 0
days_until_event = event_days[0] # Days until the next event
clean_tshirts = T # Number of clean T-shirts Ian has

# Iterate through each day
for i in range(1, day+1):
if i == days_until_event:
# Ian attends an event on this day
clean_tshirts += 1 # Ian receives a new clean t-shirt
# Calculate the days until the next event
if event_days:
event_days.pop(0) # Remove the first event day since it's already attended
if event_days:
days_until_event = event_days[0]
else:
days_until_event = float('inf') # No more events
else:
# Ian doesn't have an event on this day
if clean_tshirts == 0:
# Ian has no clean t-shirts, needs to do laundry
laundry_count += 1
clean_tshirts = T # Reset the count after doing laundry
else:
clean_tshirts -= 1 # Ian wears a clean t-shirt

# Output the result
print("Ian will have to do laundry", laundry_count, "times in the next", day, "days.")
