Python program to turn a boolean array into index array in numpy# Import numpy import numpy as np # Creating a numpy array arr = np.arange(100,1,-1) # Display original array print("Original array:\n",arr,"\n") # Creating a mask res = np.where(arr&(arr-1) == 0) # Display ...
Python >>> help(sorted) Help on built-in function sorted in module builtins: sorted(iterable, /, *, key=None, reverse=False) Return a new list containing all items from the iterable in ascending order. A custom key function can be supplied to customize the sort order, and the reverse...
The dictionary unpacking operator (**) is an awesome feature in Python. It allows you to merge multiple dictionaries into a new one, as you did in the example above. Once you’ve merged the dictionaries, you can iterate through the new dictionary as usual....
The purpose of the tutorial is to show how you can develop simple CLI applications for automating your everyday tasks by using the free PyCharm Community Edition. Although you’ll get a working passphrase generator by the end of this tutorial, please consider it merely a learning project. Nev...
The Python while loop can be used to execute a block of code for as long as a certain condition is fulfilled. While loops are primarily used in Python when the number of iterations can’t be determined at the time of writing the code. Keep reading to find out how the Python while ...
If your filter should return a boolean or other non-string value, marking it is_safe will probably have unintended consequences (such as converting a boolean False to the string ‘False’). Alternatively, your filter code can manually take care of any necessary escaping. This is necessary when...
function stringToBoolean($str){ settype($str, "boolean"); var_dump($str); } stringToBoolean("yoyo"); stringToBoolean(""); stringToBoolean("0"); Output: bool(true) bool(false) bool(false) Use the Cast Operators to Typecast String to Boolean in PHP We can easily convert a data...

So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif...
