Question

我有一个Python计算器，很快就可以做代数我是Python的新手，所以我可能搞砸了。代码的除法，乘法和指数部分不能正常工作，而其他所有功能都可以！

我尝试检查缩进。不确定“浮动”仅适用于某些操作吗？正如我说的我很新。

loop = 1
while loop == 1:
     input('Welcome to PyMath version 0.4!      >> Press [Enter] to continue <<' )
     input('Please Choose an option by typing it below  >> Press [Enter] to continue <<')
     operation = input('test score, +, -, /, *, <, >, **, help     Operation: ')

     ######here is where everything is executed!###############
     if operation == 'help':
          print('Welcome to the MathPython Help Guide!')
          print('Ensure you type the EXACT symbol or text of the funtion you want to be performed')
          input('Follow directions carefully!     >>')
          print('If any other questions are present please contact us at ########@gmail.com')
     if operation == 'test score':
          print('Two values are needed to find the test score')
          print('Please type in the total amount of questions on the test')
          totalqs = int(input('Total: '))
          print('Now, type the number of questions you got correct')
          correctqs = int(input('Correct: '))
          pct = float(correctqs / totalqs * 100)
          print('you got a(n) ' + format(correctqs) + ' out of ' + format(totalqs))
          print('That is equivelent to ' + format(pct) + '%')
          if format(pct) <= 70:
               print('You Better study! Your grade was below a 70% Which is below average')
          else:
              print('Good job on the test, keep it up!')
     if operation == '+':

     if operation == '-':
          print('First value?')
          add1 = int(input('VALUE 1: '))
          print('Second value? ')
          add2 = int(input('VALUE 2: '))
          added = float(add1 - add2)

#Division

          add2 = int(input('VALUE 2: '))
          added = float(add1 * add2)
          input(format(added))
          input('Operation done! >>Press [Enter] to go continue<<')      
 #Exponents
     if operation == '**':
          print('First value?')
          add1 = int(input('VALUE 1: '))
          print('Second value? ')
          add2 = int(input('VALUE 2: '))
          added = float(add1 ** add2)
          input(format(added))
          input('Operation done! >>Press [Enter] to go continue<<')

没有错误消息，只是在执行某些操作时不断循环回到开头

我的部分代码无法在“ While”循环中运行
