Budget App chart output seems correct but return error

I think my output is already the same with what the unit test is asking but it still returns error. please correct me if I’m wrong, thanks for reading

here is my code:

class Category:

  def __init__(self, category):
    self.ledger = []
    self.funds = 0
    self.spending = 0
    self.category = category

  def check_funds(self, amount):
    if ((self.funds - amount) < 0):
      return False
    else:
      return True

  def deposit(self, amount, desc=None):
    self.amount = amount
    self.desc = desc

    if (self.desc == None):
      self.desc = ""

    self.funds += self.amount

    self.ledger.append({"amount": self.amount, "description": self.desc})

  def withdraw(self, amount, desc=None):
    self.amount = amount
    self.desc = desc

    if (self.desc == None):
      self.desc = ""

    self.amount -= amount * 2

    if (self.check_funds(amount) == False):
      return False

    else:
      self.funds += self.amount
      self.spending += self.amount
      self.ledger.append({"amount": self.amount, "description": self.desc})
      return True

  def get_balance(self):
    return self.funds

  def transfer(self, amount, other):
    self.amount = amount
    self.desc = "Transfer to " + other.category
    other.desc = "Transfer from " + self.category
    other.amount = self.amount
    self.amount -= amount * 2

    if (self.check_funds(amount) == False):
      return False

    else:
      self.funds += self.amount
      self.spending += self.amount
      other.funds += other.amount
      self.ledger.append({"amount": self.amount, "description": self.desc})
      other.ledger.append({"amount": other.amount, "description": other.desc})
      return True

  def __str__(self):
    title = '{:*^30}'.format(self.category)
    contents = []
    for x in self.ledger:
      content = []
      for values in x.values():
        content.append(values)
      amount = content[0]
      desc = content[1]
      text = '{:<23.23}{:>7.2f}'.format(desc, amount) #23.23 means width is 23 digits and 23 digits max and cannot surpass it
      contents.append(text)
    content_str = "\n".join(contents)

    output = title + '\n' + content_str + '\n' + "Total: " + str(self.funds)
    return (output)


def create_spend_chart(categories):
  title = "Percentage spent by category"
  category_names = []
  category_spendings = []
  category_percentage = []
  chart_percentage = ['100|', ' 90|', ' 80|', ' 70|', ' 60|', ' 50|', " 40|", " 30|", " 20|", " 10|", "  0|"]
  total_spendings = 0

  #formatting for numbers
  for x in categories:
    name = x.category
    spent = round(x.spending,-1)
    total_spendings += spent
    category_names.append(name)
    category_spendings.append(spent)
    
  for x in category_spendings:
    category_percentage.append(round(x/total_spendings * 100))
    
  for x in category_percentage:
    index = 0
    for y in chart_percentage:
      number = ""
      
      for nums in y:
        if nums.isdigit():
          number += nums
          
      if float(number) <= x:
        chart_percentage[index] += " o "
      else:
        chart_percentage[index] += "   "
      index += 1
      
  percentage_output = "\n".join(chart_percentage)

  #formatting for strips
  strip = "    "
  for x in category_names:
    strip += "---"
  strip += "-"

  #formatting for names 
  length = 0
  for x in category_names:
    if length < len(x):
      length = len(x)
         
  i= 0
  names_list = []
  while i <= length:
    lines = "    "
    for x in category_names:
      if i < len(x):
        lines += " " + x[i] + " "
      else:
        lines += "   "
    i += 1
    names_list.append(lines)
  names_output = "\n".join(names_list)

  output = title + "\n" + percentage_output + "\n" + strip + "\n" + names_output
  return(output)

and here is the error code:

Looking at the test outputs, it seems there’s one space not enough at the end of each line.
