Let's say we want to calculate, 23, we want to enter this in a way that can be understood easily by the user. We want to calculate a power by using the ^ operator to represent a number raised to a certain power. Thus, to calculate 23, a user enters in, 2^3 This is shown in...
The main problem with theeval()function is as it executes arbitrary codes, this can bring unintended results. Among the three options we provide eval function is the least secure one. However, its power is bigger than the other two methods. Therefore, the best thing to do is to use theev...
In Python, strings are a common data type used to represent dates and times, but as data scientists and engineers, we’re often required to convert these strings to datetime objects to perform various operations, such as sorting or comparison. Converting strings to datetime objects can be tricky...
There are three main approaches to coding in Python. You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code ...
When you’re indenting your code, the official Python style guide called PEP 8 recommends using 4 space characters to represent one indentation level. Most text editors that are set up to work with Python files will automatically insert 4 spaces if you press the Tab key on your keyboard. You...
Python, apopular programming language, has acquired quite a reputation in the data analysis & visualization domain due to its versatility, simplicity, and extensive collection of visualization libraries. These libraries provide diverse visualization techniques to aesthetically represent complex data, ...
A string is one of the most utilized datatypes in any programming language, so much so that it can be mostly seen in almost every Python code. In Python, the ASCII value of a character is its numerical representation. It is a 7-bit number that is used to represent characters in computer...
Let’s get started with using WordNet in Python. It is included as a part of the NLTK (http://www.nltk.org/) corpus. To use it, we need to import it first. >>>fromnltk.corpusimportwordnetaswn This allows us to invoke WordNet by simply typing “wn” instead of “wordnet”. No...
The first argument is the converted bytes data length, the second argument byteorder defines the byte order to be little or big-endian, and the optional argument signed determines whether two’s complement is used to represent the integer.Performance...
To compute drawdown, you’ll need to calculate the daily returns of the stock or portfolio. Next, calculate the cumulative returns, which represent the overall performance of the investment. Now, let’s compute the drawdown by finding the peak and trough values. ...
