I'm working on a project that will allow me to document my earnings/spending's more efficiently, and I cannot seem to find how to find the latest column within a given text file, keep in mind the code is a prototype, as I only started working on it about an hour ago.
f = open('Money.txt','a')
while True:
while True:
OP = input("Operator: ")
if OP == "+" or OP == "-":
break
else:
print("Invalid Operator, please try again.\n\n")
while True:
try:
MA = int(input("Money amount: "))
break
except ValueError:
print("Numeric value only.\n\n")
while True:
if OP == "+":
MV = input("Where you recived the money: ")
break
elif OP == "-":
MV = input("Where you spent the money: ")
break
while True:
C = input('\n\nIs "' + OP + "/" + str(MA) + "/" + MV + '" correct: ')
if C.lower() == "yes":
break
elif C.lower() == "no":
print("Restarting...\n\n")
break
else:
print("Invalid response, try again.\n\n")
if C.lower() == "yes":
break
elif C.lower() == "no":
continue
fs = OP + " $" + str(MA) + " / " + MV
f.write('\n' + fs)
f.close()
print("Values written.")
# "abcde!mdam!dskm".split("/", 2) - basic idea of the code ill use after i figure out how to get latest column from text file
I'm not too great at programming, so if you see a blatant way to improve my code, go ahead and share it, any help will be appriciated!
I figured it out, its probably not the most efficient method but it works:
fc = f.readlines()
l = -1
for line in fc:
l += 1
You can then use "l" to slice your list and do whatever you need to do to it.
Note: You need to change the "f = open('Money2.txt','a')" to "f = open('Money2.txt','r+')"

Hello How can i force to make the nname to only string input because even though i put number it still continue to the next function and i only like it to be a name of the people nname= str(input()) does not work thats why im asking if there is other alternative to make it work with only a string

You can use either lower() or upper(). Please check the following answer:
if order.lower()=="milktea":
print(flvrs)
laht.append(order)
break
OR
if order.upper()=="MILKTEA":
print(flvrs)
laht.append(order)
break
When using the logical "or" operator in an if...else statement in python you have to repeat the variable as well as the value (i know that sounds confusing so look at the example)
this means that this won't work:
if order == "Milktea" or "milktea":
the correct formation should be:
if (order == "Milktea") or (order == "milktea"):
alternatively if you want to simply check one variable against a range of values check out the match...case statements in python 3.10+: https://learnpython.com/blog/python-match-case-statement/
######################################################
Remove the if order in mmu line and indent the corresponding else (code listed below)
def kuha_order():
while True:
order = input()
print(order)
if order == "Milktea":
print(flvrs)
laht.append(order)

break

you can combine this with my answer above to get what you need :)
Inputting the same character multiple times doesn’t work.
Here is my code for the relevant issue
Please be noted that I’ve unnecessarily complicated my code by working on it for a long time to resolve the problem.
I’d really appreciate a correction from anybody.
Thanks in advance
def gamefunction():
global chosenword
global wordlen
global attempts
chosenwordlist = []
tally = 1
print("\nThe word to guess is....\n")
print(chosenword)

For further understanding -
It seems like the code doesn't run through the if-else loop nested within the 'if len(userchoice.strip()) == 1:' loop
One possible solution for your problem is as below.
Extensive comments inside the code.
#Defining globals. Note: Using globals is bad practice, use function arguments instead
chosenword = 'boot'
attempts = 4
def gamefunction():
global chosenword
global attempts
#Create needed extra variables directly from input
wordlen = len(chosenword)
chosenwordlist = list(chosenword)
tally = 1
print("\nThe word to guess is....\n")
print(chosenword)
#Added whitespace for better wordlength visualisation
display = "_ " * wordlen
print(display)
print(chosenwordlist)
#This holds the letters that have been guessed already
guessedletters = []
while tally <= int(attempts):
display = ''
userchoice = input()
if len(userchoice.strip()) == 1:
#check if the guess is part of the word to guess
if userchoice in chosenwordlist:
# Check if letter has been guessed before
if userchoice in guessedletters:
print('You tried that letter already')
continue
else:
# Add the guessed letter to the list of all guessed letters and create display
guessedletters.append(userchoice)
for i in range(wordlen):
if chosenwordlist[i] in guessedletters:
display+=chosenwordlist[i]
else:
display+='_ '
else:
print("Wrong guess")
tally = tally + 1
print("\n" + display)
if display == chosenword:
tally = int(attempts) + 1
print("Congratulations\nYou guessed the word correctly")
else:
print("Invalid input\nEnter only a single letter\n")
print(display)
Doing my homework rn and a bit stuck, why does the code execute "else" even thought the "if" has been satisfied? Ignore the sloppy code, I'm very new :/
order1 = input("What would you like to order?: \n \n" + "1: " + orderBurger + "\n" + "2: " + orderFries + "\n" + "3: " + orderDrink + "\n" + "\nAnswer = ")
while order == True:
if order1 == 1:
print("You have selected to order 1: " + orderBurger)
elif order1 == 2:
print("You have selected to order 1: " + orderFries)
elif order1 == 3:
print("You have selected to order 1: " + orderDrink)
else:
print("Invalid Input")
check = input("Is this your final item?:" + "1: " + q1 + "2: " + q2 + "Answer = ")
if check == 1:
print("Your items have been added to the basket")
break
elif check == 2:
check
elif check == 3:
check
else:
print("Invalid input")
This is the output
If you use type(order1), you'll see if your answer is a string or an int. If it's a string (and I think it is), you can convert it into int using int(order1), or replace your code by if order1 == '1'
Indentation is very important in Python. Based on how the indentations are implemented, the code blocks for conditions get executed.
A misplaced indent can lead to unexpected execution of a code block.
Here is a working demo of the ordering program
# File name: order-demo.py
moreItems = True
while (moreItems == True):
order = input("\n What would you like to order?\n"
+ " 1: Burger\n 2: Fries\n 3: Drink\n Answer = ")
if ((order == "1") or (order == "2") or (order == "3")):
print("You have selected to order " + order)
print("Your item has been added to the basket.\n")
else:
print("Invalid Input")
check = input("Is this your final item?: \n 1: Yes \n 2: No \n Answer = ")
if check == "1":
print("\n Thank you. Please proceed to checkout.")
moreItems = False
elif check == "2":
print("Please continue your shopping")
else:
print("Invalid input")
Output
$ python3 order-demo.py
What would you like to order?
1: Burger
2: Fries
3: Drink
Answer = 1
You have selected to order 1
Your item has been added to the basket.
Is this your final item?:
1: Yes
2: No
Answer = 2
Please continue your shopping
What would you like to order?
1: Burger
2: Fries

Answer = 2
You have selected to order 2
Your item has been added to the basket.

2: No
Answer = 1
Thank you. Please proceed to checkout.
$
replace first line with this :
order1 = int( input("What would you like to order?: \n \n" + "1: " + orderBurger + "\n" + "2: " + orderFries + "\n" + "3: " + orderDrink + "\n" + "\nAnswer = ") )
I am here to ask another question about the code I am working on. I keep getting invalid syntax error. I asked a similar question on another account and someone answered the question and gave me a code. I edited it but i cannot seem to work it out. My project is to make a troubleshooting program for a mobile company. At the moment this is my code:
CODE:
print("Please answer 'yes' or 'no' to all questions. If you write something else instead of yes or no then your solution might not come out correctly.")
solution = "Keep holding the power on button until the screen is on. If it doesn't turn on, contact your phone provider to get a replacement."
solution2 = "Charge your phone fully and switch it on."
solution3 = "Delete some apps, you need a minimum of at least 5 GB of free memory to run the phone correcly.\nYou are probably out of memory."
sol4 = "Take out everything from the phone and put it in a bag of rice for 24-36 hours to let the rice absorb the water."
sol5 = "Reset your phone."
sol6 = "You need a screen replacement. Get it fixed!"
sol7 = "You need to get your buttons replaced!"
sol8 = "Get a screen replacement or contact your phone provider to get a phone replacement."
sol9 = "You need to update your phone software and apps."
sol10 = "You dont need to do anything. Your phone doesnt have any problems."
sol11 = "Please update your phone software."
if input("Did you buy your phone recently? ") == 'yes':
if input("Did your drop your phone? ") == 'yes':
if input("Did it become wet when you dropped it? ") == 'yes':
print(sol4)
else:
print(sol5)
else:
if input("Has your phone ever been to slow?" ) == 'yes':
print(sol5)
else:
if input("Have you got more than 30 apps?? ") == 'yes':
print(solution3)
else:
if input("Is your phone older than two years?") == 'yes':
print(no_warranty)
else:
print(warranty)
else:
print(warranty)
So my question is, how can i complete this code and how can i link questions to more questions?
Thanks!
Invalid Syntax error is because your code is not indented properly.
In python you have to indent the code the right way to make it work since there is no ; in python to end the code line:
e.g for nested code blocks:
{
Block 1
....{
....Block 2
{
....Block 3
}
}
}
Here the 4 dots represent 4 space characters.
for your code you can try like this:
if input("Did you buy your phone recently? ") == 'yes':
if input("Did your drop your phone? ") == 'yes':
if input("Did it become wet when you dropped it? ") == 'yes':
print(sol4)
else:
print(sol5)
....
Always remember, while using python always proprly indent you code otherwise it will throw invalid syntax error.

Well this was a fun one!
in def convertToNum(ch): the alpha does not equal the alpha in def outPutString(text): (missing an *) causing (in my case) tabs instead of spaces and a ? to appear at the end of my decrypted string. I would recommend using a global variable to prevent things like this happening in the future.
Your encryption algorithm worked great and didn't need any adjustment. There were some incompatible variable types in the decryption phase but I managed to get everything to work and have included the working code (my comments marked with ##) I hope this helped.
Edit: As Eric points out in the comments, if (evenNum>(oddNum)) is probably not doing what you want it to do. According to the python docs:
Sequence objects may be compared to other objects with the same sequence type. The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.
I Assume you want to compare the lengths of the two arrays to make sure they are equal. If this is the case then you would want to use if (len(evenNum)>len(oddNum))
