Python also providesrandom.randint()from the random module, which is used to generate the random integer from the given range of integers. It takes numeric values as its parameters. These will define the range of integers. So that a random integer is generated within the specified range. Note...
In other programming languages, we can define a specific set of values. To define infinity, we can use float("inf") to define a positive infinite number and for a negative infinite number, we use float("-inf"). Now, we will look at how it works in Python. Suppose we have a value...
In this example, you define a lambda function and use it to sort the items of incomes by value with sorted(). The lambda function tells sorted() to sort incomes.items() by the second element of each item, item[1], which is the income value.You may also want to iterate through the...
A Python function should always start with the def keyword, which stands for define. Then we have the name of the function (typically should be in lower snake case), followed by a pair of parenthesis() which may hold parameters of the function and a semicolon(:) at the end. ...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.

The total number of keys has been printed on the screen using the “len()” function. Method 2: Using User-Defined Function We can also define the function in the program that counts the number of keys in a dictionary. In the example given below, the user-defined function for counting ...
In this tutorial, you will create a passphrase generator in PyCharm. You’ll also learn how to: Create a project inPyCharm Community Edition. Install and import Python packages. Use the Typer library to create command line interfaces in Python. ...
