Generating random data is very important in the field of data science. From building neural network predictions, stock market data, etc., date is usually used as one of the parameters. We may need to generate random numbers between two dates for statistical analysis. This article will show how to generate k random dates between two given dates using the random and datetime modules. Datetime is Python’s built-in library for handling time. On the other hand, the random module helps in generating random numbers. So we can combine random and datetime modules to generate a random date between two dates. Syntax random.randint (start, end, k) random here refers to the Python random library. The randint method uses three important

The virtual number can receive the verification code. As long as the mobile phone number filled in during registration complies with the regulations and the mobile phone number can be connected normally, you can receive the SMS verification code. However, you need to be careful when using virtual mobile phone numbers. Some websites do not support virtual mobile phone number registration, so you need to choose a regular virtual mobile phone number service provider.

PHP image processing case: How to implement the verification code function of images. With the rapid development of the Internet, verification codes have become one of the important means to protect website security. Verification code is a verification method that uses image recognition technology to determine whether the user is a real user. This article will introduce how to use PHP to implement the verification code function of images, and come with code examples. Introduction A verification code is a picture containing random characters. The user needs to enter the characters in the picture to pass the verification. The main process of implementing verification code includes generating random characters and drawing characters into pictures.

Failure to receive the verification code on your mobile phone is caused by network problems, mobile phone settings problems, mobile phone operator problems and personal settings problems. Detailed introduction: 1. Network problems. The network environment where the mobile phone is located is unstable or the signal is weak, which may cause the verification code to be unable to be delivered in time; 2.
