Let's talk about several common data types in Python and python data types. As the name suggests, a computer is a machine that can be used for mathematical computation. Therefore, a computer program can naturally process various numerical values. However, computers can process a variety of data, such as text, graphics, audio, video, and web pages. Different data

represent an absolute value of less than about 2.22E-308 ( 0.000...0222, a decimal number with 307 0 after the decimal point. The FLOAT type and DOUBLE type occupy storage space of 4 bytes and 8 bytes, respectively. If you need to use a decimal field, the accuracy is not high, of course, with FLOAT. However, to say a word, we "civilian" data, which requires a high degree of precision? These two types have not been used so far-I have not yet encounter
