python如何查看类的函数？

2023-05-27 生活百科 python

Python是一种面向对象的编程语言，它的核心概念是类。在Python中，类是创建对象的模板，它包含了一组属性和方法。当我们需要查看类的函数时，通常有以下几种方法。一、使用help函数
Python内置的help函数可以帮助我们查看类的函数。我们可以使用help函数来获取类的文档字符串，文档字符串包含了该类的所有方法和属性的详细介绍。代码如下：

```python
class MyClass:
def func1(self):
"""
This is func1
"""
pass
def func2(self):
"""
This is func2
"""
pass
help(MyClass)
```
运行上述代码后，我们可以看到如下输出：
```
class MyClass(builtins.object)
|Methods defined here:
|
|func1(self)
|This is func1
|

|
|__module__ = '__main__'
|Module name.

|Methods inherited from builtins.object:
|
|__delattr__(self, name, /)

|
|__init__(self, /, *args, **kwargs)
|Initialize self.See help(type(self)) for accurate signature.
|
|__init_subclass__($self, /, *args, **kwargs)
|This method is called when a class is subclassed.
|
|__le__(self, other, /)
|Return self<=value.
|
|__lt__(self, other, /)
|Return self |
|__ne__(self, other, /)
|Return self!=value.
|
|__new__(*args, **kwargs) from builtins.type
|Create and return a new object.See help(type) for accurate signature.

|Helper for pickle.
|
|__repr__(self, /)
|Return repr(self).
|
|__setattr__(self, name, value, /)
|Implement setattr(self, name, value).
|
|__sizeof__(...)
|__sizeof__() -> int
|size of object in memory, in bytes
|
|__str__(self, /)
|Return str(self).
|
|__subclasshook__(...)
|Abstract classes can override this to customize issubclass().

|Static methods inherited from builtins.object:
|
|__new__(*args, **kwargs) from builtins.type
|Create and return a new object.See help(type) for accurate signature.
