int() argument must be a string, a bytes-like object or a number, not' NoneType

这个错误通常是因为你把一个 None 对象传递给了 int() 函数,而 int() 函数只接受字符串、字节对象或数字作为参数。你需要检查一下代码,找出哪个变量或表达式的值为 None,然后进行相应的处理,例如给它一个默认值或者用条件语句判断它是否为 None。另外,你也可以使用 try-except 语句来捕捉这个错误,并进行相应的处理。例如:
```
x = None
try:
y = int(x)
except TypeError:
y = 0 # 给它一个默认值或者做其他处理
```

TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
This error message typically occurs when you try to convert a variable that is None (i.e. has no value) to an integer using the int() function.
For example:
```
x = None
y = int(x) # TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
```
To fix this error, you need to ensure that the variable you are trying to convert to an integer has a valid value. You can do this by initializing the variable with a default value or by ensuring that it is assigned a value before it is used in the int() function.
For example:
```
x = 0 # default value
y = int(x) # works fine
# or
x = some_function_that_returns_a_value()
if x is not None:
y = int(x) # only convert to int if x has a value
```
int() argument must be a string, a bytes-like object or a real number, not 'NoneType'
This error occurs when the int() function is called with a value that is None instead of a string, bytes-like object, or real number. The int() function can only convert values of these types into integers.
To fix this error, you need to ensure that the value passed to the int() function is not None. You can use an if statement to check if the value is None before calling int().
For example:
```
value = None
if value is not None:
integer_value = int(value)
else:
print("Value is None.")
```
In this example, the if statement checks if the value is not None before calling the int() function. If the value is None, it prints a message instead.
