Introduction: Sogou Input method is the most useful and popular on the market input method, the most conscientious is also the Linux version, which let me and other Linux people cheered. In the new Ubuntu 16.04 on the installation of Sogou input method, encountered some problems, mainly or rely on the package is not properly installed, we look at how to solve this problem. 1. Introduction to the Environment Ubuntu 16.04, Sogou Input Method: Sogoupinyin_2.0.0.0078_amd64 2. Problem performance[HTM

3.1 basic string operations All standard sequence operations (index, sharding, multiplication, determining membership...) are also applicable to strings. However, please remember the wordsCharacter strings cannot be changed. 3.2 string formatting: Lite version The first time I came into contact with python programming, I used a little bit of string formatting content. Here I just give an example to get a rough idea: >>> format = " Hello,%s,%s enough for ya ?">>> values = ('world','hot')>>

This article only introduces some particularly useful string methods. 1. find The find method can be used to search for a substring in a long string.

Basic string manipulationAll standard sequence Operations (index, Shard, multiply, Judge membership, seek length, take maximum and minimum), also apply to strings. However, the string is immutable.String methodThere are too many ways to string, but here are just a few things that are particularly useful.FindThe Find method can look up a substring in a longer string, which returns the leftmost index at the position where the substring is located. If not found, returns-1>>> ' with a

Basic string operations All standard sequence operations (indexing, partitioning, multiplication, determining membership, length, minimum and maximum values) are also applicable to strings, as described earlier. However, note that the strings are immutable. String method: String fromStringThere are many methods for "inheritance" in the module. Here we only introduce some particularly useful methods. 1,Find FindYou can search for a substring in a long string. It returns the leftmo
