what is Attribute error and how to solve it?

Introduction

 

In this blog, we would discuss what is Attribute error and how to solve it.  Python is a powerful programming language, and it’s easy to make mistakes. One of the most common errors you’ll find in your code is when you access an attribute whose name doesn’t exist. This happens because Python uses capitalization rules that are different from those used by English-speaking people (for example, all CAPITALS) and sometimes accidentally misspells names like “attribue” or “attr_”. To fix this problem, check the variable type or module name before trying to access it again.

Solutions

 

In Python, the dir() function returns a list containing all the attributes of an object. For example:

 

class example:
    def __init__(self): 
        self.a = 'abc'
        self.b = 200

p=example()

print(vars(p))

print(dir(p))

 

The output would be :

If you want to know what other methods are available on a particular class/object, simply use help() and print(x).

 

AttributeError: ‘module’ object has no attribute ‘method’

 

If you try to call a method on a module that does not have it, the AttributeError will be raised. The following code example shows how this can be used:

 

class Mod1(object):
  def __init__(self, x):
     self.x = x 
     
mod1 = Mod1('Hello')
print(mod1.y)

 

The output :

 

The above code will throw an AttributeError if you try to call a method on a class that does not have it. This can be useful in some cases, such as when you want your custom exceptions to inherit from the built-in ones.

 

AttributeError: ‘module’ object has no attribute ‘property’

 

You are trying to access a module, but it doesn’t have the property you’re looking for.

If you are accessing a module, it is probably not a module, but a class.

If you are accessing a class, it is probably not a class, but rather some kind of function or method that has been called by another object (or perhaps even multiple objects).

 

AttributeError: ‘int’ object has no attribute ‘method’

 

AttributeError: ‘int’ object has no attribute ‘method’.

This error occurs when you try to access an attribute of an object that doesn’t exist. The syntax for this is wrong, and it’s caused by trying to use a variable or module name that isn’t compatible with the object you’re trying to access. For example:

 

a=10

b=a.append(3)

 

The output would be
