  <P>
    摆脱了
     <code>
      while True:
    </code>
     循环，这导致代码重复
     <code>
      NameError
    </code>
     异常发生。
  </p>
  <P>
    另外，移动输入
     <code>
      done
    </code>
     进入
     <code>
      try
    </code>
     块。否则，该输入将覆盖
     <code>
      done = "y"
    </code>
     声明中
     <code>
      except
    </code>
     块。
  </p>
   <pre>
    <code>
      while x <= qubits:
    while done == "n":
        print("this is qubit #",x)
        fstgat = "target"
        print("first gate is target")
        if fstgat in singates:
            #checks if there is an error from mem1 being undefined (control/target out of order)
            try:
                qstat[x]=singates[fstgat](qstat[x])
                done = input("Done with your qubit? y or n: ")
            except NameError:
                print("switching qubits - we'll come back to this one")
                #error here -> keeps saying "which gate is this target qubit for"
                done = "y"   
        else:
            print("sorry, that functionality is not yet implemented, try custom gate")
            done ="y"
    x+=1
    done = "n"
