The Maketrans and translate functions are common methods for string character encoding. This article focuses on demonstrating its basic usage and the difference between operating in different versions. This article refers to the 2. The x version refers to more than 2.6 versions, and the 3.X version refers to more than 3.1 versions.
The 2.X version essentially divides the string into two types: A Unicode string and a 8-bit string, str, which contains b
Today, I read an example in SQL cookbook. I saw two functions replace and translate have doubts. I feel that these two functions have the same role, the examples in the book are not very clear.
