title: Why is it saying that the = in bold is an invalid syntax?
body: <pre><code>print('Select operation')
  print('Choose from:')
  print('+')
  print('-')
  print('*')
  print('/')
  
  choice=input('Enter choice (+,-,*,/):')
  
  num1=int(input('Enter first number:'))
  num2=int(input('Enter second number:'))
  
  if choice== '+':
  print(num1,'+',num1,'=', (num1+num2))
  while restart **=** input('Do you want to restart the calculator y/n'):
      if restart == 'y':t
          print('restart')
          else restart == 'n':
              print('Thanks for using my program')
              break
  
   elif choice== '-':
  print(num1,'-',num2,'=', (num1-num2))
  
  elif choice== '*':
  print(num1,'*',num2,'=', (num1*num2))
  
  elif choice== '/':
  print(num1,'/',num2,'=',(num1/num2))
  
  else:
  print('Invalid input')
  </code></pre>

  <p>Thank you,
