What's Gil?
The first thing to be clear is that Gil is not a Python feature, it is a concept introduced when implementing the Python parser (CPython). Just like C + + is a set of language (syntax) standards, but can be compiled into executable code
Found that there is a large number of IP to our API collection, so write this script to get which IP only access to a single interface, but not access to other interfaces, generally such behavior, is abnormal.The log format of the front-end load
If you need to know how to match Chinese characters in Python, we must first look at the following table
UTF8[x01-x7f]| [XC0-XDF] [x80-xbf]| [Xe0-xef] [X80-XBF] {2}| [Xf0-xff] [X80-XBF] {3}UTF16[X00-xd7] [xe0-xff]| [XD8-XDF] [X00-xff]
For example, there is a file below
2312
We are looking forward to
2,23,11,1The way to solve the problem:The occurrence of the text as a key, the number of occurrences as value, and then excluded by value after output
It is best to output from
A small program is being written Miniblogs updater, you need to calculate the number of words entered by the user. Because the length of the Chinese-English character encoding is different, if you use the Len () function in Python, it calculates the

One of the powerful features of Python is its parsing of the list, which provides a compact way to map a list to another list by applying a function to each element in the list.
Instance
A = [' Cat ', ' window ', ' defenestrate ']For X in
