Try-除了ValueError循环

Question

def enterNumber(): 
    number = input("Please enter a number to convert to binary. ") 
    while True: 
     try: 
      int(number) 
      convertDenary() 
     except ValueError: 
      enterNumber() 
def convertDenary(): 
     binaryNumber = ['','','','','','','',''] 
     print(enterNumber()) 
     if enterNumber() > 128: 
      enterNumber() - 128 
      binaryNumber[0] == 1 
enterNumber() 

Try- Except ValueError循环，因为我打算它，但它不会中断。我试过在int（number）下加入break，删除while True:并加入convertDenary()看看它是否会强制子程序停止并启动另一个，但它仍然不起作用。

我得到一个无限循环的“请输入数字以转换为二进制。” 任何想法？

def convertToBinary(number): 
    if number > 1: 
     convertToBinary(number//2) 
    elif number<1: 
     enterNumber() 

    print(number % 2,end = '') 

def enterNumber(): 
    number = (input("Please enter a number to convert to binary : ")) 
    try: 
     convertToBinary(int(number)) 
    except Exception as e: 
     print(e) 

enterNumber()
