![]() ![]() In this loop, item is a temporary variable that takes on the value of each item in sequence, one at a time, and the indented block of code underneath the for statement is executed once for each item in the sequence.įor example, here is a for loop that iterates over a list of numbers and prints each one: numbers = ![]() The basic syntax for a for loop is: for item in sequence: Python for loopsĪ for loop in Python is a way to iterate over a sequence of items, such as a list or a range of numbers. These constants can be used to manipulate strings in various ways, such as generating random passwords or filtering out unwanted characters. In Python, the string module provides a collection of constants (i.e., predefined values that cannot be changed) representing ASCII character sets such as lowercase and uppercase letters, digits, and punctuation. It's commonly used in various applications such as games, simulations, and data analysis. It provides functions to generate random integers, random floats, random choices from a sequence, and more. The Python random module is a built-in library that allows programmers to generate random numbers, sequences, and selections. Here's a link to the Python docs section. Examples of commonly used built-in libraries in Python include random, math, datetime, os, and sys. These libraries come with the standard Python installation and cover a wide range of areas, such as math, datetime, string manipulation, file I/O, networking, and more. ![]() Python built-in libraries are pre-written pieces of code that provide a set of functionalities to developers without the need for them to write the code themselves. Python built-in libraries, for loops, and functions Python built-in libraries The script then generates two passwords using the generate_password function, one with a length of 12 characters and the other with a length of 20 characters, and prints them to the console using the print function. ![]() During each iteration, a random character is selected from the characters string using the random.choice method and added to the password string.įinally, the password string is returned by the generate_password function. A for loop is then used to iterate password_length number of times. Next, an empty string named password is created to store the generated password. Inside the generate_password function, a string named characters is created by concatenating three strings, string.ascii_letters, string.digits, and string.punctuation, which contain the lowercase and uppercase letters of the alphabet, digits from 0 to 9, and various punctuation characters, respectively. Then, a function named generate_password is defined that takes an integer argument, password_length, which determines the length of the password to be generated. The script starts by importing two modules, random and string, that allow for generating random values and manipulating strings, respectively. In the video, I create a basic Python script that generates random passwords of different lengths. This is a simple Python project that's great for learning standard Python libraries, Python for loops, and function signatures.
