First install the PIL package easy_install PIL, and then install wheezy. captcha easy_install wheezy. captcha.It is easy to generate a verification code after installation: The code is as follows:Copy code Captcha_image_t = captcha (drawings = [Backgroun

Construction random is a common function in the program, Python built-in support for this, concise and efficient. This blog mainly records some of the functions commonly used in random.random.random(): Returns a floating-point number from 0 to one that is left closed right.Return the next random floating point number in the range [0.0, 1.0].random.uniform(a, b):

This article describes in detail how to generate a random password using Python. interested partners can refer to the standard instance to share with you the implementation process of generating a random password using Python, for your reference, the specific content is as f

Python implements two weight-based random number methods This article mainly introduces two methods for implementing weight-based random numbers in Python. This article provides the implementation code directly. For more information, see Problem: For example, if we want to s

In this paper, we describe the method of generating random passwords by Python3, which has a wide range of practical value in Python programming. Here's how: The main implementation of this paper is to create a 8-bit random password (uppercase and lowercase letters + numbers), using Python3 to generate a

This article describes how to generate random values without duplicates in Python. The example analyzes the implementation skills of Python Algorithm Implementation and Python built-in method, which is very simple and practical, f

This article mainly introduces the python Implementation of random Maze generation algorithm core code sharing, this article contains a simple maze game complete code, need friends can refer to the complete code download: http://xiazai.bitsCN.com/201407/tools/python-migong.rar Recently I studied the generation algorit

The standard example for everyone to share the python generated random password implementation process for your reference, the specific content as follows Wrote a program, mainly used to detect the MySQL database empty password and weak password, Here, three types of weak passwords are defined: 1. Continuous numbers , such as 123456, are implemented in Get_weak

This article describes how to generate pseudo-random text based on the Markov chain in Python. it is a small implementation based on the Markov algorithm and fully reflects the use of Python in scientific computing, for more information, see the definition of Wolfram. A Markov chain is a set of

Full code Download: Http://xiazai.bitsCN.com/201407/tools/python-migong.rar Recently, the generation algorithm of the maze was studied, and then a simple online maze game was done. The game address and the corresponding open source project address can be found through the links above. The open source project does not contain the server-side code, because the server-side code is simply too simple. The following is a simple introduction to the

This article mainly introduces a simple method to generate random IP addresses using Python scripts, and you can set the IP address value range by yourself. For more information, see Requirement In an application, you need to generate random IP addresses according to certain rules. The rules are given in a CIDR format similar to 192.168.11.0/24.

implementation using the request file descriptor from the operating system for I/O operations:The $ script Gets the file descriptor for the standard input (terminal), which is subsequently used to get input and output to the screen. In fact, reading the standard input, I prefer to use the raw_input () This function, but has been implemented anyway. The reason for the use of Sys.stdout.write () in the input is that after changing the properties of the

The work needs to determine whether a URL in a text to access the normal, and randomly get the n rows of the normal access to the URL data, my idea is: Read the text of each row of data, with Urlopen access, will return the URL of the status Code 200 to a list, get the length of the list, Use random to generate a random value as the list subscript to get the row data. The specific
