Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? This tutorial will discuss the object has no attribute python error in Python. Lets say you code a class named Human with the following definitions: Next, you created an object from this class and called the eat() method: You receive an error because the eat() method is not defined in the class: if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'sebhastian_com-large-leaderboard-2','ezslot_2',133,'0','0'])};__ez_fad_position('div-gpt-ad-sebhastian_com-large-leaderboard-2-0');To fix this you need to define the eat() method inside the class as follows: Now Python can run the eat() method and you wont receive the error. the E-step.

The following example uses one space for indentations: This one uses two spaces for indentations: And this uses four spaces for indentations: When you incorrectly indent a function, as in not giving any indent to the walk() method, then that method is defined outside of the class: You need to appropriately indent the method to make it a member of the class.
