syntax is elegant, consistent, and easy to get started, and the linux O M mentioned by the subject does not require high execution efficiency. I personally think that the python syntax is not as elegant as ruby, and it is more difficult to get started than ruby. There are many open-source python libraries, but there is no such thing. Ruby and python can both us

Problems that beginners often encounter when learning python. 1. python2 or python3? New users often think about this for a long time. The syntaxes of 2 and 3 are roughly the same, but the changes are not significant. For example, print xxx in python2, and print (xxx) is used in python3 ), however, in the current situation, python3 will be the mainstream in the future, and the update speed of python3 on the
