Syntax object.__iand__(self, other) The Python __iand__() magic method implements the in-place bitwise AND x &= y that calculates the result of the bitwise AND operation x & y, and assigns it to the first operands’ variable x. This type of in-place operation is also called augmented arithmetic assignment. The method simply returns the new value … Read more
What is a Depth-First Search (DFS) Algorithm? Building on our previous story about graphs and graph traversal algorithms, this time we will look into a depth-first search algorithm. A depth-search algorithm also traverses a graph by exploring it vertex-by-vertex, but it does it by following the vertical order of the vertices. Although the depth-first search … Read more
Method Name Method Description dict.clear() Removes all elements from the dictionary dict.copy() Creates a shallow copy of the dictionary dict.fromkeys() Create a new dictionary from a given iterable of keys dict.get() Returns value associated with a key, or default value if key does not exist dict.items() Outputs a list of (key, value) tuple pairs of … Read more
💡 Summary: To get a list of all the keys stored in a dictionary, use the dict.keys() method that returns a dict_keys object that is iterable but not ordered and not subscriptable. In this article, I will show some examples of the dict.keys() method to, hopefully, give you a better idea of how the method … Read more
Summary: When working with Python dictionaries, in some cases you may want to access a specific value of a certain item, this is where the dict.get() method comes in handy. Definition: Python’s dict.get() method expects a key argument. If the specified key is in the dictionary, the method will output the value associated with the … Read more
📖 Summary: There are many different ways to copy the dictionary data structure objects in Python. In this tutorial, I will show you the built-in dict.copy() method, which is a very useful method for copying dictionaries. Description Whenever the dict.copy() method is applied to a dictionary, a new dictionary is made, which contains a copy … Read more
Syntax object.__ipow__(self, other) The Python __ipow__() magic method implements the in-place exponentiation x **= y that calculates the result of the power function x ** y, and assignsit to the first operands’ variable x. This type of in-place operation is also called augmented arithmetic assignment. The method simply returns the new value to be assigned … Read more
Summary: The dictionary data structure has many useful methods, one of these methods is the dict.items() method. To be able to iterate and show the dictionary elements, the Python dictionary items() method does this functionality. The dict.items() method shows the elements taken up by a dictionary as a list of key-value tuples. Definition: The dict.items() … Read more
Overview In Python, there are different strategies to create, open, close, read, write, update and delete the files. It permits the users to deal with the files, i.e., read and write, alongside numerous other file handling operations. In this article, we are going to look at the various methods to write text in a line … Read more
Syntax pandas.pivot(data, index=None, columns=None, values=None) Return Value: The return value for the pivot() function is a reshaped DataFrame organized by index/column values. Background Direct quote from the Pandas Documentation website: This function does not support data aggregation. If there are multiple values, they will result in a Multi-Index in the columns. This article delves into … Read more
This article explains the concept of gas in Ethereum and the basics you need to know when developing smart contracts in Solidity. What is Gas in Ethereum? In Ethereum, we have to pay for each computational operation, measured in the unit called gas. In the Ethereum documentation, gas is defined as follows: “Gas refers to … Read more
Syntax object.__imod__(self, other) The Python __imod__() magic method implements the in-place modulo operation x %= y that calculates the modulo operation x % y, and assigns the result to the first operands variable x. This type of in-place operation is also called augmented arithmetic assignment. The method simply returns the new value to be assigned … Read more
