1. How can I read such books more effectively?
From Baidu:
Practice has shown that reading books directly is not very effective. You must learn by doing, learn by doing, read the knowledge of books, and try it through engineering practice immediately, in order to discover problems and advantages. Therefore, I think it is reasonable for us to arrange projects while attending classes.

, and Phantom reads (lowest isolation level, high concurrency performance)
L read_committed: unrepeatable read and phantom read (locking the row being read)
L repeatable_read will trigger phantom read (Lock all rows read)
L serializable ensures that all situations will not occur (Lock table)
the key to unrepeatable reading is to modify : in the same condition, the data you read is read again and the value is different. the focus of phantom

Reading Floating Point data from a text file is one of the most common tasks. python does not have an input function like scanf, but we can use regular expressions to extract floating point data from the read string.
Copy codeThe Code is as follows:Import reFp = open ('C:/1.txt ', 'R ')S = fp. readline ()Print (s)AList = re. findall ('([-+]? \ D + (\. \ d *)? | \. \ D +) ([eE] [-+]? \ D + )? ', S) # use regular expressions to search stringsPrint (aLi

The solution is to modify the configuration file of PostgreSQL.Postgresql. conf, set the output type of bytea_output to the escape type (escape) output, that is, bytea_output = 'escape '(if there is # above, delete and enable the configuration ), then reload the PostgreSQL configuration to make the modification take effect, so that the binary data can be decoded and output to the file.
