First of all I would just like to mention - I am a beginner, I am still learning. This code is probably an abomination and I might be missing something obvious, please be nice.
My question is this. I have written a for loop to find the highest earning employee but I would like for the user to select a start and end date for their earnings to be calculated.
So for example my program should be able to calculate an employees earning from 01/05/2021 to 09/05/2021.
The only thing I'm struggling with is how to reference the date, I've been googling for an hour but the responses are just too complicated for me.

I was trying to run a script in PythonAnywhere (this is my first time using it), but it said my code had an EOF error. When I run it in flask_app.py, it works, but when I refresh the website and try it on the site itself, it gives me this error.

I'm a new learner for python and I'm trying to make a program that prints in invoice of all the items + their price + their quantity. each item is in separate line.
I have got tot he point where I print each item in a line, but I keep overwriting the old values by the last value entered. how can I prevent this?
this is the code:
print("This program prints your invoices."
"\nPlease enter the item identification, item cost and quantity sold when promted."
"\nEnter 'done' when no more items"
"\n=========================================")
saveqty= ()
savetprice=()
qtysum= 0 #quantity =qty for short
sumprice=0
list1 = []
totalprice=0
while True:
itemid = input('Item identification: ')
if itemid == "done":
break
if len(itemid)<3:
print("item identification should be at least 3 characters long, try again")
continue
else:
list11 = list[itemid]
list1 +=[itemid]
qtysold = input("Qty sold: ")
try:
qtysold =int(qtysold)
except ValueError:
print("must be an integer value, try again")
continue
qtysum+=qtysold
try:
itemprice = float(input("Item price: "))
savetprice= (itemprice)
except ValueError:
print("item price must be numerical value, try again")
continue
totalprices= (qtysold*itemprice)
totalprice+=totalprices
for elem in list1:
print(qtysold,'x ',elem, '# ', savetprice, 'SAR', '===', totalprices)
total = sumprice
itemtotal = qtysum
print("=========================================\nNo. of items purchased: ", itemtotal,"\nTotal price is: ", totalprice, "SAR")
Below is the code that fixes your problem
print("This program prints your invoices."
"\nPlease enter the item identification, item cost and quantity sold when promted."
"\nEnter 'done' when no more items"
"\n=========================================")
saveqty = ()
savetprice = ()
qtysum = 0 # quantity =qty for short
sumprice = 0
list1 = []
totalprice = 0
while True:
itemid = input('Item identification: ')
if itemid == "done":
break
if len(itemid) < 3:
print("item identification should be at least 3 characters long, try again")
continue
qtysold = input("Qty sold: ")
try:
qtysold = int(qtysold)
except ValueError:
print("must be an integer value, try again")
continue
qtysum += qtysold
try:
itemprice = float(input("Item price: "))
savetprice = (itemprice)
except ValueError:
print("item price must be numerical value, try again")
continue
totalprices = (qtysold * itemprice)
totalprice += totalprices
list1.append((itemid, qtysold, savetprice, totalprices))
for elem, qtysold, savetprice, totalprices in list1:
print(qtysold, 'x ', elem, '# ', savetprice, 'SAR', '===', totalprices)
total = sumprice
itemtotal = qtysum
print("=========================================\nNo. of items purchased: ", itemtotal, "\nTotal price is: ", totalprice, "SAR")
Output:
This program prints your invoices.
Please enter the item identification, item cost and quantity sold when promted.
Enter 'done' when no more items
=========================================
Item identification: 123
Qty sold: 5
Item price: 20
Item identification: 456
Qty sold: 3
Item price: 30
Item identification: done
5 x 123 # 20.0 SAR === 100.0
3 x 456 # 30.0 SAR === 90.0
=========================================
No. of items purchased: 8
Total price is: 190.0 SAR
Note: You need to save all the information (e.g., itemid, qtysold) in the while loop to list1 if you want to print them out later. Otherwise, qtysold and totalprices will always keep the last value when exiting the while loop. This explains the reason for the problem you are facing.

I do not know why this error is occurring .I am a bit new to python and have not encounter such error before.Please tell me how to improve my code such that this error does not occur again. Thanks to anyone who helps!
For eg:
S/n Items Quantity Unit Price Price
1. Rice 3 $5.00 $15.00
2. Rice 4 $5.00 $20.00
3. Water 4 $3.00 $12.00
and user wants to remove the second item, it the output after the function has been carried out should be
S/n Items Quantity Unit Price Price
1. Rice 3 $5.00 $15.00
2. Water 4 $3.00 $12.00
I can't paste the formatted code in the comment, I will write it in the answer, I hope to understand.
The list is very inconvenient to do this operation
In [1]: import pandas as pd
In [5]: d = pd.DataFrame([['Rice', 3, '$5.0', '$15.0'], ['Water', 4, '$3.0', '$12.0']], columns=['Items', 'Quantity', 'Unit Price', 'Price'])

Items Quantity Unit Price Price
0 Rice 3 $5.0 $15.0

1 Water 4 $3.0 $12.0
In [16]: d.append([{"Items": "Rice", "Quantity": 3, "Unit Price": "$5.0", "Price": "$20.0"}], ignore_index=True)

I am doing a University project to create a plan ordering ticket program, so far these are what I have done:
First, this is the function finding the seat type:
def choosingFare():
print("Please choose the type of fare. Fees are displayed below and are in addtion to the basic fare.")
print("Please note choosing Frugal fare means you will not be offered a seat choice, it will be assigned to the ticketholder at travel time.")

listofType[0] = "Business: +$275"
listofType[1] = "Economy: +$25"
listofType[2] = "Frugal: $0"
print("(0)Business +$275")
print("(1)Economy +$25")
print("(2)Frugal: $0")
type = int(input())
while type > 2:
print("Invalid choice, please try again")
type = int(input())
print("Your choosing type of fare is: " + listofType[type])
if type == 0:
price1 = 275
else:
if type == 1:
price1 = 25
else:
price1 = 0
return price1, listofType[type]
And this is a function finding the destination:
def destination():
print("Please choose a destination and trip length")
print("(money currency is in: Australian Dollars: AUD)")
print("Is this a Return trip(R) or One Way trip(O)?")
direction = input()
while direction != "R" and direction != "O":
print("Invalid, please choose again!")

print("Is this a Return trip(R) or One Way trip(O)?")
if direction == "O":
print("(0)Cairns oneway: $250")
print("(2)Sydney One Way: $420")
print("(4)Perth One Way: $510")
else:
print("(1)Cairns Return: $400")
print("(3)Sydney Return: $575")
print("(5)Perth Return: $700")
typeofTrip = [""] * (6)

typeofTrip[1] = "Cairns Return: $400"
typeofTrip[2] = "Sydney One Way: $420"
typeofTrip[3] = "Sydney Return: $575"
typeofTrip[4] = "Perth One Way: $510"
typeofTrip[5] = "Perth Return: $700"
trip = int(input())
while trip > 5:
print("Invalid, please choose again")
trip = int(input())
if trip == 0:
price = 250
else:
if trip == 1:
price = 400
else:

else:
if trip == 4:
price = 510
else:

print("Your choice of destination and trip length is: " + typeofTrip[trip])
return price, typeofTrip[trip]
And this is the function calculating the total price:
def sumprice():
price = destination()
price1 = choosingFare()
price2 = choosingseat()
sumprice = price1 + price2 + price
print("How old is the person travelling?(Travellers under 16 years old will receive a 50% discount for the child fare.)")
age = float(input())
if age < 16 and age > 0:
sumprice = sumprice / 2
else:
sumprice = sumprice
return sumprice
The error I have:
line 163, in <module> main()
line 145, in main sumprice = sumprice()
line 124, in sumprice
sumprice = price1 + price2 + price
TypeError: can only concatenate tuple (not "int") to tuple
Can someone help me? I am really stuck.
I can't return all the
These functions return 2 values each: destination(), choosingFare(), choosingseat().
Returning multiple values at once returns a tuple of those values:
For example:
return price, typeofTrip[trip] # returns (price, typeofTrip[trip])
So while calculating the sum of all prices, you need to access price, price1, price2 from the tuples:
sumprice = price1[0] + price2[0] + price3[0]
Alternatively: You can edit the code to return list/ dictionary or some other data structure as per your convenience.
First let me explain what happends when you write. return price, typeofTrip[trip].
The above line will return a tuple of two values.
Now for sumprice I think what you want is sum of all prices. So you just want to sum first element of returned values.
This should work for your case.
sumprice = price1[0] + price2[0] + price3[0]
