There’s no specific method for formatting numbers here. Just think of lines being printed like a dot matrix printer (is this reference still useable?).
You’ll need to break up the problem’s parts and re-assemble them as lines.
I think i came to the same conclusion but i am unsure how to carry it out. I am thinking about putting my first numbers on one line of a list and my second numbers on a second list and printing one then the other but i got stuck at the part with the operators as in how i would account for different operators.
thank you, however i am still unsure how to add the spaces, backspaces, and line
in the correct places while in a for loop or would i need to add them using one of the methods that were described
def arithmetic_arranger(problems, show_answers=False):
firstN = [] # List to hold the first numbers
secondN = [] # List to hold the second numbers
operators = [] # List to hold the operators ('+' or '-')
lines = [] # List to hold the formatted lines for output
results = [] # List to hold the results of operations
# Check if there are more than 5 problems
if len(problems) > 5:
return "Error: Too many problems."
# Loop through each problem
for item in problems:
subitems = item.split() # Split the problem into components
# Check if the numbers contain only digits
if not subitems[0].isdigit() or not subitems[2].isdigit():
return "Error: Numbers must only contain digits."
# Check if numbers are more than four digits
if len(subitems[0]) > 4 or len(subitems[2]) > 4:
return "Error: Numbers cannot be more than four digits."
# Check if the operator is valid
if subitems[1] not in ['+', '-']:
return "Error: Operator must be '+' or '-'."
# Store the first and second numbers, as well as the operator
firstN.append(subitems[0])
secondN.append(subitems[2])
operators.append(subitems[1])
# Compute results for addition or subtraction
result = int(subitems[0]) + int(subitems[2]) if subitems[1] == '+' else int(subitems[0]) - int(subitems[2])
results.append(result) # Store the result
return arranged_problems # Return the final formatted output
what i am not sure about is how to make a loop that will add the necessary spaces between the numbers, combining two lists together for the case of the operators and second numbers lists to that they are in one list and additionally how to dynamically create lines that will grow and shrink depending on the length of the largest number.
because i am not sure i can make a solution that is efficient, id be long winded and unnecessary.
but if i did i suppose id make a loop that will compare the first number on the list with the next, if the first number is larger id store that number in a variable then id move on the the next, the the second number is larger id store that one in a variable then more on to the next comparison untill the list ends.
