New users are often intimidated upon entering the crypto space. Hurdles like user-friendliness, private keys, encryption, and wallets is enough to make a beginner’s head spin. With so many complexities to start off, it’s no wonder why mass adoption is slow to come. Design/UX Argent hopes to solve this issue by having an app that … Read more
El modo más pitónico de convertir una lista de cadenas a una lista de enteros es utilizar la comprensión de listas [int(x) for x in strings]. Recorre todos los elementos de la lista y convierte cada elemento de la lista x en un valor entero utilizando la función incorporada int(x). Este artículo muestra las formas … Read more
Syntax object.__hash__(x) The Python __hash__() method implements the built-in hash() function. So, when you cal hash(x), Python attempts to call x.__hash__(). If the return value is not an integer or the x.__hash__() method is not defined, Python will raise a TypeError. We call this a “Dunder Method” for “Double Underscore Method” (also called “magic method”). … Read more
Syntax object.__complex__(x) The Python __complex__() method implements the built-in complex() function. So, when you cal complex(x), Python attempts to call x.__complex__(). If the return value is not a complex number or the x.__complex__() method is not defined for an object on which you call complex(x), Python will raise a TypeError. We call this a “Dunder … Read more

Syntax object.__bytes__(self) The Python __bytes__() method implements the built-in bytes() function. So, when you cal bytes(x), Python attempts to call x.__bytes__(). If the return value is not a Bytes object or the x.__bytes__() method is not defined for an object on which you call bytes(x), Python will raise a TypeError. We call this a “Dunder … Read more
[toc] Overview Problem Statement: Given a Pandas Dataframe, how to get the row count of the data frame? Example: In the following example, we have a dataframe that has 5 rows in it. Thus, the question here is how do we get the number of rows in the dataframe? (Output expected is 5 in this … Read more
Syntax object.__bool__(self) The Python __bool__() method implements the built-in bool() function. So, when you cal bool(x), Python attempts to call x.__bool__(). If the return value is not a Boolean, Python raises a TypeError. We call this a “Dunder Method” for “Double Underscore Method” (also called “magic method”). To get a list of all dunder methods … Read more
